+the PR is accepted, *all* code should be updated as soon as possible to reflect the new
 conventions.
 
-## Pull Requests
+Rust coding conventions
+---
 
-Small, frequent PRs are much preferred to large, infrequent ones. A large PR is
-difficult to review, can block others from making progress, and can quickly get
-its author into "rebase hell". A large PR oftentimes arises when one change
-requires another, which requires another, and then another. When you notice
-those dependencies, put the fix into a commit of its own, then checkout a new
-branch, and cherry-pick it.
+* All Rust code is formatted using the latest version of `rustfmt`. Once installed, it will be
+  updated automatically when you update the compiler with `rustup`.
 
-```bash
-$ git commit -am "Fix foo, needed by bar"
-$ git checkout master
-$ git checkout -b fix-foo
-$ git cherry-pick fix-bar
-$ git push --set-upstream origin fix-foo
-```
+* All Rust code is linted with Clippy. If you'd prefer to ignore its advice, do so explicitly:
 
-Open a PR to start the review process and then jump back to your original
-branch to keep making progress. Consider rebasing to make your fix the first
-commit:
-
-```bash
-$ git checkout fix-bar
-$ git rebase -i master <Move fix-foo to top>
-```
-
-Once the commit is merged, rebase the original branch to purge the
-cherry-picked commit:
-
-```bash
-$ git pull --rebase upstream master
-```
-
-### How big is too big?
-
-If there are no functional changes, PRs can be very large and that's no
-problem. If, however, your changes are making meaningful changes or additions,
-then about 1,000 lines of changes is about the most you should ask a Solana
-maintainer to review.
-
-### Should I send small PRs as I develop large, new components?
-
-Add only code to the codebase that is ready to be deployed. If you are building
-a large library, consider developing it in a separate git repository. When it
-is ready to be integrated, the Solana maintainers will work with you to decide
-on a path forward. Smaller libraries may be copied in whereas very large ones
-may be pulled in with a package manager.
-
-## Getting Pull Requests Merged
-
-There is no single person assigned to watching GitHub PR queue and ushering you
-through the process. Typically, you will ask the person that wrote a component
-to review changes to it. You can find the author using `git blame` or asking on
-Discord.  When working to get your PR merged, it's most important to understand
-that changing the code is your priority and not necessarily a priority of the
-person you need an approval from. Also, while you may interact the most with
-the component author, you should aim to be inclusive of others. Providing a
-detailed problem description is the most effective means of engaging both the
-component author and other potentially interested parties.
-
-Consider opening all PRs as Draft Pull Requests first. Using a draft PR allows
-you to kickstart the CI automation, which typically takes between 10 and 30
-minutes to execute. Use that time to write a detailed problem description. Once
-the description is written and CI succeeds, click the "Ready to Review" button
-and add reviewers. Adding reviewers before CI succeeds is a fast path to losing
-reviewer engagement. Not only will they be notified and see the PR is not yet
-ready for them, they will also be bombarded them with additional notifications
-each time you push a commit to get past CI or until they "mute" the PR. Once
-muted, you'll need to reach out over some other medium, such as Discord, to
-request they have another look. When you use draft PRs, no notifications are
-sent when you push commits and edit the PR description. Use draft PRs
-liberally.  Don't bug the humans until you have gotten past the bots.
-
-### What should be in my PR description?
-
-Reviewing code is hard work and generally involves an attempt to guess the
-author's intent at various levels. Please assume reviewer time is scarce and do
-what you can to make your PR as consumable as possible. Inspired by techniques
-for writing good whitepapers, the guidance here aims to maximize reviewer
-engagement.
-
-Assume the reviewer will spend no more than a few seconds reading the PR title.
-If it doesn't describe a noteworthy change, don't expect the reviewer to click
-to see more.
-
-Next, like the abstract of a whitepaper, the reviewer will spend ~30 seconds
-reading the PR problem description. If what is described there doesn't look
-more important than competing issues, don't expect the reviewer to read on.
-
-Next, the reviewer will read the proposed changes. At this point, the reviewer
-needs to be convinced the proposed changes are a *good* solution to the problem
-described above.  If the proposed changes, not the code changes, generates
-discussion, consider closing the PR and returning with a design proposal
-instead.
-
-Finally, once the reviewer understands the problem and agrees with the approach
-to solving it, the reviewer will view the code changes. At this point, the
-reviewer is simply looking to see if the implementation actually implements
-what was proposed and if that implementation is maintainable. When a concise,
-readable test for each new code path is present, the reviewer can safely ignore
-the details of its implementation. When those tests are missing, expect to
-either lose engagement or get a pile of review comments as the reviewer
-attempts to consider every ambiguity in your implementation.
-
-### The PR Title
-
-The PR title should contain a brief summary of the change, from the perspective
-of the user. Examples of good titles:
-
-* Add rent to accounts
-* Fix out-of-memory error in validator
-* Clean up `process_message()` in runtime
-
-The conventions here are all the same as a good git commit title:
-
-* First word capitalized and in the imperative mood, not past tense ("add", not
-  "added")
-* No trailing period
-* What was done, whom it was done to, and in what context
-
-### The PR Problem Statement
-
-The git repo implements a product with various features. The problem statement
-should describe how the product is missing a feature, how a feature is
-incomplete, or how the implementation of a feature is somehow undesirable. If
-an issue being fixed already describes the problem, go ahead and copy-paste it.
-As mentioned above, reviewer time is scarce. Given a queue of PRs to review,
-the reviewer may ignore PRs that expect them to click through links to see if
-the PR warrants attention.
-
-### The Proposed Changes
-
-Typically the content under the "Proposed changes" section will be a bulleted
-list of steps taken to solve the problem. Oftentimes, the list is identical to
-the subject lines of the git commits contained in the PR. It's especially
-generous (and not expected) to rebase or reword commits such that each change
-matches the logical flow in your PR description.
-
-### When will my PR be reviewed?
-
-PRs are typically reviewed and merged in under 7 days. If your PR has been open
-for longer, it's a strong indicator that the reviewers aren't confident the
-change meets the quality standards of the codebase. You might consider closing
-it and coming back with smaller PRs and longer descriptions detailing what
-problem it solves and how it solves it. Old PRs will be marked stale and then
-closed automatically 7 days later.
-
-### How to manage review feedback?
-
-After a reviewer provides feedback, you can quickly say "acknowledged, will
-fix" using a thumb's up emoji. If you're confident your fix is exactly as
-prescribed, add a reply "Fixed in COMMIT\_HASH" and mark the comment as
-resolved. If you're not sure, reply "Is this what you had in mind?
-COMMIT\_HASH" and if so, the reviewer will reply and mark the conversation as
-resolved. Marking conversations as resolved is an excellent way to engage more
-reviewers. Leaving conversations open may imply the PR is not yet ready for
-additional review.
-
-### When will my PR be re-reviewed?
-
-Recall that once your PR is opened, a notification is sent every time you push
-a commit.  After a reviewer adds feedback, they won't be checking on the status
-of that feedback after every new commit. Instead, directly mention the reviewer
-when you feel your PR is ready for another pass.
-
-## Draft Pull Requests
-
-If you want early feedback on your PR, use GitHub's "Draft Pull Request"
-mechanism. Draft PRs are a convenient way to collaborate with the Solana
-maintainers without triggering notifications as you make changes. When you feel
-your PR is ready for a broader audience, you can transition your draft PR to a
-standard PR with the click of a button.
-
-Do not add reviewers to draft PRs.  GitHub doesn't automatically clear
-approvals when you click "Ready for Review", so a review that meant "I approve
-of the direction" suddenly has the appearance of "I approve of these changes."
-Instead, add a comment that mentions the usernames that you would like a review
-from. Ask explicitly what you would like feedback on.
-
-## Rust coding conventions
-
-* All Rust code is formatted using the latest version of `rustfmt`. Once
-  installed, it will be updated automatically when you update the compiler with
-`rustup`.
-
-* All Rust code is linted with Clippy. If you'd prefer to ignore its advice, do
-  so explicitly:
-
-  ```rust #[allow(clippy::too_many_arguments)] ```
+  ```rust
+  #[cfg_attr(feature = "cargo-clippy", allow(too_many_arguments))]
+  ```
 
   Note: Clippy defaults can be overridden in the top-level file `.clippy.toml`.
 
-* For variable names, when in doubt, spell it out. The mapping from type names
-  to variable names is to lowercase the type name, putting an underscore before
-each capital letter. Variable names should *not* be abbreviated unless being
-used as closure arguments and the brevity improves readability. When a function
-has multiple instances of the same type, qualify each with a prefix and
-underscore (i.e. alice\_keypair) or a numeric suffix (i.e. tx0).

+  prefix and underscore (i.e. alice_keypair) or a numeric suffix (i.e. tx0).
 
-* For function and method names, use `<verb>_<subject>`. For unit tests, that
-  verb should always be `test` and for benchmarks the verb should always be
-`bench`. Avoid namespacing function names with some arbitrary word. Avoid
-abbreviating words in function names.

-* As they say, "When in Rome, do as the Romans do." A good patch should
-  acknowledge the coding conventions of the code that surrounds it, even in the
-case where that code has not yet been updated to meet the conventions described
-here.

-## Terminology
+Terminology
+---
 
-Inventing new terms is allowed, but should only be done when the term is widely
-used and understood. Avoid introducing new 3-letter terms, which can be
-confused with 3-letter acronyms.

-[Terms currently in use](docs/src/terminology.md)
+Some terms we currently use regularly in the codebase:
 
+* fullnode: n. A fully participating network node.
+* hash: n. A SHA-256 Hash.
+* keypair: n. A Ed25519 key-pair, containing a public and private key.

-## Design Proposals
-
-Solana's architecture is described by docs generated from markdown files in
-the `docs/src/` directory, maintained by an *editor* (currently @garious). To
-add a design proposal, you'll need to include it in the
-[Accepted Design Proposals](https://docs.solana.com/proposals/accepted-design-proposals)
-section of the Solana docs.  Here's the full process:
-
-1. Propose a design by creating a PR that adds a markdown document to the
-   `docs/src/proposals` directory and references it from the [table of
-   contents](docs/src/SUMMARY.md). Add any relevant *maintainers* to the PR
-   review.
-2. The PR being merged indicates your proposed change was accepted and that the
-   maintainers support your plan of attack.
-3. Submit PRs that implement the proposal. When the implementation reveals the
-   need for tweaks to the proposal, be sure to update the proposal and have that
-   change reviewed by the same people as in step 1.
-4. Once the implementation is complete, submit a PR that moves the link from
-   the Accepted Proposals to the Implemented Proposals section.

-# Building
+Blockchain, Rebuilt for Scale
+===
 
-## **1. Install rustc, cargo and rustfmt.**
+Solana&trade; is a new blockchain architecture built from the ground up for scale. The architecture supports
+up to 710 thousand transactions per second on a gigabit network.
+
+Disclaimer
+===
+
+All claims, content, designs, algorithms, estimates, roadmaps, specifications, and performance measurements described in this project are done with the author's best effort.  It is up to the reader to check and validate their accuracy and truthfulness.  Furthermore nothing in this project constitutes a solicitation for investment.
+
+Introduction
+===
+
+It's possible for a centralized database to process 710,000 transactions per second on a standard gigabit network if the transactions are, on average, no more than 176 bytes. A centralized database can also replicate itself and maintain high availability without significantly compromising that transaction rate using the distributed system technique known as Optimistic Concurrency Control [\[H.T.Kung, J.T.Robinson (1981)\]](http://citeseerx.ist.psu.edu/viewdoc/summary?doi=10.1.1.65.4735). At Solana, we're demonstrating that these same theoretical limits apply just as well to blockchain on an adversarial network. The key ingredient? Finding a way to share time when nodes can't trust one-another. Once nodes can trust time, suddenly ~40 years of distributed systems research becomes applicable to blockchain!
+
+> Perhaps the most striking difference between algorithms obtained by our method and ones based upon timeout is that using timeout produces a traditional distributed algorithm in which the processes operate asynchronously, while our method produces a globally synchronous one in which every process does the same thing at (approximately) the same time. Our method seems to contradict the whole purpose of distributed processing, which is to permit different processes to operate independently and perform different functions. However, if a distributed system is really a single system, then the processes must be synchronized in some way. Conceptually, the easiest way to synchronize processes is to get them all to do the same thing at the same time. Therefore, our method is used to implement a kernel that performs the necessary synchronization--for example, making sure that two different processes do not try to modify a file at the same time. Processes might spend only a small fraction of their time executing the synchronizing kernel; the rest of the time, they can operate independently--e.g., accessing different files. This is an approach we have advocated even when fault-tolerance is not required. The method's basic simplicity makes it easier to understand the precise properties of a system, which is crucial if one is to know just how fault-tolerant the system is. [\[L.Lamport (1984)\]](http://citeseerx.ist.psu.edu/viewdoc/summary?doi=10.1.1.71.1078)
+
+Furthermore, and much to our surprise, it can be implemented using a mechanism that has existed in Bitcoin since day one. The Bitcoin feature is called nLocktime and it can be used to postdate transactions using block height instead of a timestamp. As a Bitcoin client, you'd use block height instead of a timestamp if you don't trust the network. Block height turns out to be an instance of what's being called a Verifiable Delay Function in cryptography circles. It's a cryptographically secure way to say time has passed. In Solana, we use a far more granular verifiable delay function, a SHA 256 hash chain, to checkpoint the ledger and coordinate consensus. With it, we implement Optimistic Concurrency Control and are now well en route towards that theoretical limit of 710,000 transactions per second.
+
+
+Testnet Demos
+===
+
+The Solana repo contains all the scripts you might need to spin up your own
+local testnet. Depending on what you're looking to achieve, you may want to
+run a different variation, as the full-fledged, performance-enhanced
+multinode testnet is considerably more complex to set up than a Rust-only,
+singlenode testnode.  If you are looking to develop high-level features, such
+as experimenting with smart contracts, save yourself some setup headaches and
+stick to the Rust-only singlenode demo.  If you're doing performance optimization
+of the transaction pipeline, consider the enhanced singlenode demo. If you're
+doing consensus work, you'll need at least a Rust-only multinode demo. If you want
+to reproduce our TPS metrics, run the enhanced multinode demo.
+
+For all four variations, you'd need the latest Rust toolchain and the Solana
+source code:
+
+First, install Rust's package manager Cargo.
 
 ```bash
 $ curl https://sh.rustup.rs -sSf | sh
 $ source $HOME/.cargo/env
-$ rustup component add rustfmt
 ```
 
-Please sure you are always using the latest stable rust version by running:
+Now checkout the code from github:
+
+```bash
+$ git clone https://github.com/solana-labs/solana.git
+$ cd solana
+```
+
+The demo code is sometimes broken between releases as we add new low-level
+features, so if this is your first time running the demo, you'll improve
+your odds of success if you check out the
+[latest release](https://github.com/solana-labs/solana/releases)
+before proceeding:
+
+```bash
+$ git checkout v0.8.0
+```
+
+Configuration Setup
+---
+
+The network is initialized with a genesis ledger and leader/validator configuration files.
+These files can be generated by running the following script.
+
+```bash
+$ ./multinode-demo/setup.sh
+```
+
+Drone
+---
+
+In order for the leader, client and validators to work, we'll need to
+spin up a drone to give out some test tokens.  The drone delivers Milton
+Friedman-style "air drops" (free tokens to requesting clients) to be used in
+test transactions.
+
+Start the drone on the leader node with:
+
+```bash
+$ ./multinode-demo/drone.sh
+```
+
+Singlenode Testnet
+---
+
+Before you start a fullnode, make sure you know the IP address of the machine you
+want to be the leader for the demo, and make sure that udp ports 8000-10000 are
+open on all the machines you want to test with.
+
+Now start the server in a separate shell:
+
+```bash
+$ ./multinode-demo/leader.sh
+```
+
+Wait a few seconds for the server to initialize. It will print "leader ready..." when it's ready to
+receive transactions. The leader will request some tokens from the drone if it doesn't have any.
+The drone does not need to be running for subsequent leader starts.
+
+Multinode Testnet
+---
+
+To run a multinode testnet, after starting a leader node, spin up some validator nodes in
+separate shells:
+
+```bash
+$ ./multinode-demo/validator.sh
+```
+
+To run a performance-enhanced leader or validator (on Linux),
+[CUDA 9.2](https://developer.nvidia.com/cuda-downloads) must be installed on
+your system:
+
+```bash
+$ ./fetch-perf-libs.sh
+$ SOLANA_CUDA=1 ./multinode-demo/leader.sh
+$ SOLANA_CUDA=1 ./multinode-demo/validator.sh
+```
+
+
+Testnet Client Demo
+---
+
+Now that your singlenode or multinode testnet is up and running let's send it
+some transactions!
+
+In a separate shell start the client:
+
+```bash
+$ ./multinode-demo/client.sh # runs against localhost by default
+```
+
+What just happened? The client demo spins up several threads to send 500,000 transactions
+to the testnet as quickly as it can. The client then pings the testnet periodically to see
+how many transactions it processed in that time. Take note that the demo intentionally
+floods the network with UDP packets, such that the network will almost certainly drop a
+bunch of them. This ensures the testnet has an opportunity to reach 710k TPS. The client
+demo completes after it has convinced itself the testnet won't process any additional
+transactions. You should see several TPS measurements printed to the screen. In the
+multinode variation, you'll see TPS measurements for each validator node as well.
+
+Public Testnet
+--------------
+In this example the client connects to our public testnet. To run validators on the testnet you would need to open udp ports `8000-10000`.
+
+```bash
+$ ./multinode-demo/client.sh --network $(dig +short testnet.solana.com):8001 --identity config-private/client-id.json --duration 60
+```
+
+You can observe the effects of your client's transactions on our [dashboard](https://metrics.solana.com:3000/d/testnet/testnet-hud?orgId=2&from=now-30m&to=now&refresh=5s&var-testnet=testnet)
+
+
+Linux Snap
+---
+A Linux [Snap](https://snapcraft.io/) is available, which can be used to
+easily get Solana running on supported Linux systems without building anything
+from source.  The `edge` Snap channel is updated daily with the latest
+development from the `master` branch.  To install:
+
+```bash
+$ sudo snap install solana --edge --devmode
+```
+
+(`--devmode` flag is required only for `solana.fullnode-cuda`)
+
+Once installed the usual Solana programs will be available as `solona.*` instead
+of `solana-*`.  For example, `solana.fullnode` instead of `solana-fullnode`.
+
+Update to the latest version at any time with:
+
+```bash
+$ snap info solana
+$ sudo snap refresh solana --devmode
+```
+
+### Daemon support
+The snap supports running a leader, validator or leader+drone node as a system
+daemon.
+
+Run `sudo snap get solana` to view the current daemon configuration.  To view
+daemon logs:
+1. Run `sudo snap logs -n=all solana` to view the daemon initialization log
+2. Runtime logging can be found under `/var/snap/solana/current/leader/`,
+`/var/snap/solana/current/validator/`, or `/var/snap/solana/current/drone/` depending
+on which `mode=` was selected.  Within each log directory the file `current`
+contains the latest log, and the files `*.s` (if present) contain older rotated
+logs.
+
+Disable the daemon at any time by running:
+
+```bash
+$ sudo snap set solana mode=
+```
+
+Runtime configuration files for the daemon can be found in
+`/var/snap/solana/current/config`.
+
+#### Leader daemon
+
+```bash
+$ sudo snap set solana mode=leader
+```
+
+If CUDA is available:
+
+```bash
+$ sudo snap set solana mode=leader enable-cuda=1
+```
+
+`rsync` must be configured and running on the leader.
+
+1. Ensure rsync is installed with `sudo apt-get -y install rsync`
+2. Edit `/etc/rsyncd.conf` to include the following
+```
+[config]
+path = /var/snap/solana/current/config
+hosts allow = *
+read only = true
+```
+3. Run `sudo systemctl enable rsync; sudo systemctl start rsync`
+4. Test by running `rsync -Pzravv rsync://<ip-address-of-leader>/config
+solana-config` from another machine.  **If the leader is running on a cloud
+provider it may be necessary to configure the Firewall rules to permit ingress
+to port tcp:873, tcp:9900 and the port range udp:8000-udp:10000**
+
+
+To run both the Leader and Drone:
+
+```bash
+$ sudo snap set solana mode=leader+drone
+
+```
+
+#### Validator daemon
+
+```bash
+$ sudo snap set solana mode=validator
+
+```
+If CUDA is available:
+
+```bash
+$ sudo snap set solana mode=validator enable-cuda=1
+```
+
+By default the validator will connect to **testnet.solana.com**, override
+the leader IP address by running:
+
+```bash
+$ sudo snap set solana mode=validator leader-address=127.0.0.1 #<-- change IP address
+```
+
+It's assumed that the leader will be running `rsync` configured as described in
+the previous **Leader daemon** section.

+Solana uses a channel-oriented, date-based branching process described [here](https://github.com/solana-labs/solana/blob/master/rfcs/rfc-005-branches-tags-and-channels.md).
 
-```
+## Release Steps
 
-### master branch
-All new development occurs on the `master` branch.
+### Changing channels
 
-Bug fixes that affect a `vX.Y` branch are first made on `master`.  This is to
-allow a fix some soak time on `master` before it is applied to one or more
-stabilization branches.
+When cutting a new channel branch these pre-steps are required:
 
-Merging to `master` first also helps ensure that fixes applied to one release
-are present for future releases.  (Sometimes the joy of landing a critical
-release blocker in a branch causes you to forget to propagate back to
-`master`!)"
+1. Pick your branch point for release on master.
+2. Create the branch.  The name should be "v" + the first 2 "version" fields from Cargo.toml.  For example, a Cargo.toml with version = "0.9.0" implies the next branch name is "v0.9".
+3. Update Cargo.toml to the next semantic version (e.g. 0.9.0 -> 0.10.0) by running `./scripts/increment-cargo-version.sh`.
+4. Push your new branch to solana.git
+5. Land your Cargo.toml change as a master PR.
 
-Once the bug fix lands on `master` it is cherry-picked into the `vX.Y` branch
-and potentially the `vX.Y-1` branch.  The exception to this rule is when a bug
-fix for `vX.Y` doesn't apply to `master` or `vX.Y-1`.
+At this point, ci/channel-info.sh should show your freshly cut release branch as "BETA_CHANNEL" and the previous release branch as "STABLE_CHANNEL".
 
-Immediately after a new stabilization branch is forged, the `Cargo.toml` minor
-version (*Y*) in the `master` branch is incremented by the release engineer.
-Incrementing the major version of the `master` branch is outside the scope of
-this document.
+### Updating channels (i.e. "making a release")
 
-### v*X.Y* stabilization branches
-These are stabilization branches for a given milestone.  They are created off
-the `master` branch as late as possible prior to the milestone release.
+We use [github's Releases UI](https://github.com/solana-labs/solana/releases) for tagging a release.
 
-### v*X.Y.Z* release tag
-The release tags are created as desired by the owner of the given stabilization
-branch, and cause that *X.Y.Z* release to be shipped to https://crates.io
-
-Immediately after a new v*X.Y.Z* branch tag has been created, the `Cargo.toml`
-patch version number (*Z*) of the stabilization branch is incremented by the
-release engineer.
-
-## Channels
-Channels are used by end-users (humans and bots) to consume the branches
-described in the previous section, so they may automatically update to the most
-recent version matching their desired stability.
-
-There are three release channels that map to branches as follows:
-* edge - tracks the `master` branch, least stable.
-* beta - tracks the largest (and latest) `vX.Y` stabilization branch, more stable.
-* stable - tracks the second largest `vX.Y` stabilization branch, most stable.
-
-## Steps to Create a Branch
-
-### Create the new branch
-1. Check out the latest commit on `master` branch:
-    ```
-    git fetch --all
-    git checkout upstream/master
-    ```
-1. Determine the new branch name.  The name should be "v" + the first 2 version fields
-   from Cargo.toml.  For example, a Cargo.toml with version = "0.9.0" implies
-   the next branch name is "v0.9".
-1. Create the new branch and push this branch to the `solana` repository:
-    ```
-    git checkout -b <branchname>
-    git push -u origin <branchname>
-    ```
-
-Alternatively use the Github UI.
-
-### Update master branch to the next release minor version
-
-1. After the new branch has been created and pushed, update the Cargo.toml files on **master** to the next semantic version (e.g. 0.9.0 -> 0.10.0) with:
-     ```
-     $ scripts/increment-cargo-version.sh minor
-     $ ./scripts/cargo-for-all-lock-files.sh update
-     ```
-1. Push all the changed Cargo.toml and Cargo.lock files to the `master` branch with something like:
-    ```
-    git co -b version_update
-    git ls-files -m | xargs git add
-    git commit -m 'Bump version to X.Y+1.0'
-    git push -u origin version_update
-    ```
-1. Confirm that your freshly cut release branch is shown as `BETA_CHANNEL` and the previous release branch as `STABLE_CHANNEL`:
-    ```
-    ci/channel_info.sh
-    ```
-
-## Steps to Create a Release
-
-### Create the Release Tag on GitHub
-
-1. Go to [GitHub Releases](https://github.com/solana-labs/solana/releases) for tagging a release.
-1. Click "Draft new release".  The release tag must exactly match the `version`
-   field in `/Cargo.toml` prefixed by `v`.
-   1.  If the Cargo.toml version field is **0.12.3**, then the release tag must be **v0.12.3**
-1. Make sure the Target Branch field matches the branch you want to make a release on.
-   1.  If you want to release v0.12.0, the target branch must be v0.12
-1. Fill the release notes.
-   1.  If this is the first release on the branch (e.g. v0.13.**0**), paste in [this
-   template](https://raw.githubusercontent.com/solana-labs/solana/master/.github/RELEASE_TEMPLATE.md).  Engineering Lead can provide summary contents for release notes if needed.
-   1. If this is a patch release, review all the commits since the previous release on this branch and add details as needed.
-1. Click "Save Draft", then confirm the release notes look good and the tag name and branch are correct.
-1. Ensure all desired commits (usually backports) are landed on the branch by now.
-1. Ensure the release is marked **"This is a pre-release"**.  This flag will need to be be removed manually after confirming the the Linux binary artifacts appear at a later step.
-1. Go back into edit the release and click "Publish release" while being marked as a pre-release.
-1. Confirm there is new git tag with intended version number at the intended revision after running `git fetch` locally.
-
-
-### Update release branch with the next patch version
-
-1. After the new release has been tagged, update the Cargo.toml files on **release branch** to the next semantic version (e.g. 0.9.0 -> 0.9.1) with:
-     ```
-     $ scripts/increment-cargo-version.sh patch
-     $ ./scripts/cargo-for-all-lock-files.sh tree
-     ```
-1. Push all the changed Cargo.toml and Cargo.lock files to the **release branch** with something like:
-    ```
-    git co -b version_update origin/vX.Y
-    git add -u
-    git commit -m 'Bump version to X.Y.Z+1'
-    git push -u <user-remote> version_update
-    ```
-1. Open a PR against origin/vX.Y and then merge the PR after passing CI.
-
-### Prepare for the next release
-1.  Go to [GitHub Releases](https://github.com/solana-labs/solana/releases) and create a new draft release for `X.Y.Z+1` with empty release notes.  This allows people to incrementally add new release notes until it's time for the next release
-    1. Also, point the branch field to the same branch and mark the relese as **"This is a pre-release"**.
-1.  Go to the [Github Milestones](https://github.com/solana-labs/solana/milestones).  Create a new milestone for the `X.Y.Z+1`, move over
-unresolved issues still in the `X.Y.Z` milestone, then close the `X.Y.Z` milestone.
-
-### Verify release automation success
-Go to [Solana Releases](https://github.com/solana-labs/solana/releases) and click on the latest release that you just published.
-Verify that all of the build artifacts are present, then the uncheck **"This is a pre-release"** for the release.
-
-Build artifacts can take up to 60 minutes after creating the tag before
-appearing.  To check for progress:
-* The `solana-secondary` Buildkite pipeline handles creating the Linux release artifacts and updated crates.  Look for a job under the tag name of the release: https://buildkite.com/solana-labs/solana-secondary.
-* The macOS and Windows release artifacts are produced by Travis CI: https://travis-ci.com/github/solana-labs/solana/branches
-
-[Crates.io](https://crates.io/crates/solana) should have an updated Solana version.  This can take 2-3 hours, and sometimes fails in the `solana-secondary` job.
-If this happens and the error is non-fatal, click "Retry" on the "publish crate" job
-
-### Update software on devnet.solana.com/testnet.solana.com/mainnet-beta.solana.com
-See the documentation at https://github.com/solana-labs/cluster-ops/
+1. Go [there ;)](https://github.com/solana-labs/solana/releases).
+2. Click "Draft new release".
+3. If the first major release on the branch (e.g. v0.8.0), paste in [this template](https://raw.githubusercontent.com/solana-labs/solana/master/.github/RELEASE_TEMPLATE.md) and fill it in.
+4. Test the release by generating a tag using semver's rules.  First try at a release should be <branchname>.X-rc.0.
+5. Verify release automation:
+   1. [Crates.io](https://crates.io/crates/solana) should have an updated Solana version.
+   2. ...
+6. After testnet deployment, verify that testnets are running correct software.  http://metrics.solana.com should show testnet running on a hash from your newly created branch.

-* Participants must complete KYC and sign the participation agreement here when the registrations are open https://solana.com/validator-registration. Security exploits will still be assessed and open for submission at all times. This needs only be done prior to distribution of tokens.
-
-Notes:
-* All locked tokens can be staked during the lockup period

-## Incident Response Process
-
-In case an incident is discovered or reported, the following process will be
-followed to contain, respond and remediate:
-
-### 1. Establish a new draft security advisory
-In response to an email to security@solana.com, a member of the `solana-labs/admins` group will
-1. Create a new draft security advisory for the incident at https://github.com/solana-labs/solana/security/advisories
-1. Add the reporter's github user and the `solana-labs/security-incident-response` group to the draft security advisory
-1. Create a private fork of the repository (grey button towards the bottom of the page)
-1. Respond to the reporter by email, sharing a link to the draft security advisory
-
-### 2. Triage
-Within the draft security advisory, discuss and determine the severity of the
-issue. If necessary, members of the `solana-labs/security-incident-response`
-group may add other github users to the advisory to assist.
-
-If it is determined that this not a critical network issue then the advisory
-should be closed and if more follow-up is required a normal Solana public github
-issue should be created.
-
-### 3. Prepare Fixes
-For the affected branches, typically all three (edge, beta and stable), prepare
-a fix for the issue and push them to the corresponding branch in the private
-repository associated with the draft security advisory.
-
-There is no CI available in the private repository so you must build from source
-and manually verify fixes.
-
-Code review from the reporter is ideal, as well as from multiple members of the
-core development team.
-
-### 4. Notify Security Group Validators
-Once an ETA is available for the fix, a member of the
-`solana-labs/security-incident-response` group should notify the validators so
-they can prepare for an update using the "Solana Red Alert" notification system.
-
-The teams are all over the world and it's critical to provide actionable
-information at the right time. Don't be the person that wakes everybody up at
-2am when a fix won't be available for hours.
-
-### 5. Ship the patch
-Once the fix is accepted, a member of the
-`solana-labs/security-incident-response` group should prepare a single patch
-file for each affected branch. The commit title for the patch should only
-contain the advisory id, and not disclose any further details about the
-incident.
-
-Copy the patches to https://release.solana.com/ under a subdirectory named after
-the advisory id (example:
-https://release.solana.com/GHSA-hx59-f5g4-jghh/v1.4.patch). Contact a member of
-the `solana-labs/admins` group if you require access to release.solana.com
-
-Using the "Solana Red Alert" channel:
-1. Notify validators that there's an issue and a patch will be provided in X minutes
-2. If X minutes expires and there's no patch, notify of the delay and provide a
-   new ETA
-3. Provide links to patches of https://release.solana.com/ for each affected branch
-
-Validators can be expected to build the patch from source against the latest
-release for the affected branch.
-
-Since the software version will not change after the patch is applied, request
-that each validator notify in the existing channel once they've updated. Manually
-monitor the roll out until a sufficient amount of stake has updated - typically
-at least 33.3% or 66.6% depending on the issue.
-
-### 6. Public Disclosure and Release
-Once the fix has been deployed to the security group validators, the patches from the security
-advisory may be merged into the main source repository. A new official release
-for each affected branch should be shipped and all validators requested to
-upgrade as quickly as possible.
-
-### 7. Security Advisory Bounty Accounting and Cleanup
-
-If this issue is eligible for a bounty, prefix the title of the security
-advisory with one of the following, depending on the severity:
-* `[Bounty Category: Critical: Loss of Funds]`
-* `[Bounty Category: Critical: Loss of Availability]`
-* `[Bounty Category: Critical: DoS]`
-* `[Bounty Category: Critical: Other]`
-* `[Bounty Category: Non-critical]`
-* `[Bounty Category: RPC]`
-
-Confirm with the reporter that they agree with the severity assessment, and
-discuss as required to reach a conclusion.
-
-We currently do not use the Github workflow to publish security advisories.
-Once the issue and fix have been disclosed, and a bounty category is assessed if
-appropriate, the GitHub security advisory is no longer needed and can be closed.
-
-Bounties are currently awarded once a quarter (TODO: link to this process, or
-inline the workflow)

-## Overview
-
-An exchange is a marketplace where one asset can be traded for another.  This
-demo demonstrates one way to host an exchange on the Solana blockchain by
-emulating a currency exchange.
-
-The assets are virtual tokens held by investors who may post order requests to
-the exchange.  A Matcher monitors the exchange and posts swap requests for
-matching orders.  All the transactions can execute concurrently.
-
-## Premise
-
-- Exchange
-  -  An exchange is a marketplace where one asset can be traded for another.
-     The exchange in this demo is the on-chain program that implements the
-     tokens and the policies for trading those tokens.
-- Token
-  - A virtual asset that can be owned, traded, and holds virtual intrinsic value
-    compared to other assets.  There are four types of tokens in this demo, A,
-    B, C, D.  Each one may be traded for another.
-- Token account
-  - An account owned by the exchange that holds a quantity of one type of token.
-- Account request
-  - A request to create a token account
-- Token request
-  - A request to deposit tokens of a particular type into a token account.
-- Asset pair
-  - A struct with fields Base and Quote, representing the two assets which make up a 
-    trading pair,  which themselves are Tokens. The Base or 'primary' asset is the
-    numerator and the Quote is the denominator for pricing purposes.
-- Order side
-  - Describes which side of the market an investor wants to place a trade on. Options
-    are "Bid" or "Ask", where a bid represents an offer to purchase the Base asset of
-    the AssetPair for a sum of the Quote Asset and an Ask is an offer to sell Base asset
-    for the Quote asset.
-- Price ratio
-  -  An expression of the relative prices of two tokens. Calculated with the Base
-     Asset as the numerator and the Quote Asset as the denominator. Ratios are 
-     represented as fixed point numbers.  The fixed point scaler is defined in
-     [exchange_state.rs](https://github.com/solana-labs/solana/blob/c2fdd1362a029dcf89c8907c562d2079d977df11/programs/exchange_api/src/exchange_state.rs#L7)
-- Order request
-  - A Solana transaction sent by a trader to the exchange to submit an order. 
-    Order requests are made up of the token pair, the order side (bid or ask),
-    quantity of the primary token, the price ratio, and the two token accounts
-    to be credited/deducted.  An example trade request looks like "T AB 5 2" 
-    which reads "Exchange 5 A tokens to B tokens at a price ratio of 1:2"  A fulfilled trade would result in 5 A tokens
-    deducted and 10 B tokens credited to the trade initiator's token accounts.
-    Successful order requests result in an order.
-- Order
-  - The result of a successful order request.  orders are stored in
-    accounts owned by the submitter of the order request.  They can only be
-    canceled by their owner but can be used by anyone in a trade swap.  They
-    contain the same information as the order request.
-- Price spread
-  - The difference between the two matching orders. The spread is the
-    profit of the Matcher initiating the swap request.
-- Match requirements
-  - Policies that result in a successful trade swap.
-- Match request
-  - A request to fill two complementary orders (bid/ask), resulting if successful,
-    in a trade being created.
-- Trade
-  - A successful trade is created from two matching orders that meet
-    swap requirements which are submitted in a Match Request by a Matcher and
-    executed by the exchange. A trade may not wholly satisfy one or both of the
-    orders in which case the orders are adjusted appropriately. Upon execution,
-    tokens are distributed to the traders' accounts and any overlap or 
-    "negative spread" between orders is deposited into the Matcher's profit
-    account.  All successful trades are recorded in the data of a new solana 
-    account for posterity.
-- Investor
-  - Individual investors who hold a number of tokens and wish to trade them on
-    the exchange.  Investors operate as Solana thin clients who own a set of
-    accounts containing tokens and/or order requests.  Investors post
-    transactions to the exchange in order to request tokens and post or cancel
-    order requests.
-- Matcher
-  - An agent who facilitates trading between investors.  Matchers operate as
-    Solana thin clients who monitor all the orders looking for a trade
-    match.  Once found, the Matcher issues a swap request to the exchange.
-    Matchers are the engine of the exchange and are rewarded for their efforts by
-    accumulating the price spreads of the swaps they initiate.  Matchers also
-    provide current bid/ask price and OHLCV (Open, High, Low, Close, Volume)
-    information on demand via a public network port.
-- Transaction fees
-  - Solana transaction fees are paid for by the transaction submitters who are
-    the Investors and Matchers.
-
-## Exchange startup
-
-The exchange is up and running when it reaches a state where it can take
-investors' trades and Matchers' match requests.  To achieve this state the
-following must occur in order:
-
-- Start the Solana blockchain
-- Start the  thin-client
-- The Matcher subscribes to change notifications for all the accounts owned by
-  the exchange program id.  The subscription is managed via Solana's JSON RPC
-  interface.
-- The Matcher starts responding to queries for bid/ask price and OHLCV
-
-The Matcher responding successfully to price and OHLCV requests is the signal to
-the investors that trades submitted after that point will be analyzed.  <!--This
-is not ideal, and instead investors should be able to submit trades at any time,
-and the Matcher could come and go without missing a trade.  One way to achieve
-this is for the Matcher to read the current state of all accounts looking for all
-open orders.-->
-
-Investors will initially query the exchange to discover their current balance
-for each type of token.  If the investor does not already have an account for
-each type of token, they will submit account requests.  Matcher as well will
-request accounts to hold the tokens they earn by initiating trade swaps.

-
-For this demo investors or Matcher can request more tokens from the exchange at
-any time by submitting token requests. In non-demos, an exchange of this type
-would provide another way to exchange a 3rd party asset into tokens.
-
-To request tokens, investors submit transfer requests:
-
-```rust
-pub enum ExchangeInstruction {
-    /// Transfer tokens between two accounts
-    /// key 0 - Account to transfer tokens to
-    /// key 1 - Account to transfer tokens from.  This can be the exchange program itself,
-    ///         the exchange has a limitless number of tokens it can transfer.
-    TransferRequest(Token, u64),
-}
-```
-
-## Order Requests
-
-When an investor decides to exchange a token of one type for another, they
-submit a transaction to the Solana Blockchain containing an order request, which,
-if successful, is turned into an order.  orders do not expire but are
-cancellable. <!-- orders should have a timestamp to enable trade
-expiration -->  When an order is created, tokens are deducted from a token
-account and the order acts as an escrow.  The tokens are held until the
-order is fulfilled or canceled. If the direction is `To`, then the number
-of `tokens` are deducted from the primary account, if `From` then `tokens`
-multiplied by `price` are deducted from the secondary account.  orders are
-no longer valid when the number of `tokens` goes to zero, at which point they
-can no longer be used. <!-- Could support refilling orders, so order
-accounts are refilled rather than accumulating -->
-
-```rust
-/// Direction of the exchange between two tokens in a pair
-pub enum Direction {
-    /// Trade first token type (primary) in the pair 'To' the second
-    To,
-    /// Trade first token type in the pair 'From' the second (secondary)
-    From,
-}
-
-pub struct OrderRequestInfo {
-    /// Direction of trade
-    pub direction: Direction,
-
-    /// Token pair to trade
-    pub pair: TokenPair,
-
-    /// Number of tokens to exchange; refers to the primary or the secondary depending on the direction
-    pub tokens: u64,
-
-    /// The price ratio the primary price over the secondary price.  The primary price is fixed
-    /// and equal to the variable `SCALER`.
-    pub price: u64,
-
-    /// Token account to deposit tokens on successful swap
-    pub dst_account: Pubkey,
-}
-
-pub enum ExchangeInstruction {
-    /// order request
-    /// key 0 - Signer
-    /// key 1 - Account in which to record the swap
-    /// key 2 - Token account associated with this trade
-    TradeRequest(TradeRequestInfo),
-}
-
-/// Trade accounts are populated with this structure
-pub struct TradeOrderInfo {
-    /// Owner of the order
-    pub owner: Pubkey,
-    /// Direction of the exchange
-    pub direction: Direction,
-    /// Token pair indicating two tokens to exchange, first is primary
-    pub pair: TokenPair,
-    /// Number of tokens to exchange; primary or secondary depending on direction
-    pub tokens: u64,
-    /// Scaled price of the secondary token given the primary is equal to the scale value
-    /// If scale is 1 and price is 2 then ratio is 1:2 or 1 primary token for 2 secondary tokens
-    pub price: u64,
-    /// account which the tokens were source from.  The trade account holds the tokens in escrow
-    /// until either one or more part of a swap or the trade is canceled.
-    pub src_account: Pubkey,
-    /// account which the tokens the tokens will be deposited into on a successful trade
-    pub dst_account: Pubkey,
-}
-```
-
-## Order cancellations
-
-An investor may cancel a trade at anytime, but only trades they own.  If the
-cancellation is successful, any tokens held in escrow are returned to the
-account from which they came.
-
-```rust
-pub enum ExchangeInstruction {
-    /// order cancellation
-    /// key 0 - Signer
-    /// key 1 -order to cancel
-    TradeCancellation,
-}
-```
-
-## Trade swaps
-
-The Matcher is monitoring the accounts assigned to the exchange program and
-building a trade-order table.  The order table is used to identify
-matching orders which could be fulfilled.  When a match is found the
-Matcher should issue a swap request.  Swap requests may not satisfy the entirety
-of either order, but the exchange will greedily fulfill it.  Any leftover tokens
-in either account will keep the order valid for further swap requests in
-the future.
-
-Matching orders are defined by the following swap requirements:
-
-- Opposite polarity (one `To` and one `From`)
-- Operate on the same token pair
-- The price ratio of the `From` order is greater than or equal to the `To` order
-- There are sufficient tokens to perform the trade
-
-Orders can be written in the following format:
-
-`investor direction pair quantity price-ratio`
-
-For example:
-
-- `1 T AB 2 1`
-  - Investor 1 wishes to exchange 2 A tokens to B tokens at a ratio of 1 A to 1
-    B
-- `2 F AC 6 1.2`
-  - Investor 2 wishes to exchange A tokens from 6 B tokens at a ratio of 1 A
-    from 1.2 B
-
-An order table could look something like the following. Notice how the columns
-are sorted low to high and high to low, respectively.  Prices are dramatic and
-whole for clarity.
-
-|Row| To          | From       |
-|---|-------------|------------|
-| 1 | 1 T AB 2 4  | 2 F AB 2 8 |
-| 2 | 1 T AB 1 4  | 2 F AB 2 8 |
-| 3 | 1 T AB 6 6  | 2 F AB 2 7 |
-| 4 | 1 T AB 2 8  | 2 F AB 3 6 |
-| 5 | 1 T AB 2 10 | 2 F AB 1 5 |
-
-As part of a successful swap request, the exchange will credit tokens to the
-Matcher's account equal to the difference in the price ratios or the two orders.
-These tokens are considered the Matcher's profit for initiating the trade.
-
-The Matcher would initiate the following swap on the order table above:
-
-  - Row 1, To:   Investor 1 trades 2 A tokens to 8 B tokens
-  - Row 1, From: Investor 2 trades 2 A tokens from 8 B tokens
-  - Matcher takes 8 B tokens as profit
-
-Both row 1 trades are fully realized, table becomes:
-
-|Row| To          | From       |
-|---|-------------|------------|
-| 1 | 1 T AB 1 4  | 2 F AB 2 8 |
-| 2 | 1 T AB 6 6  | 2 F AB 2 7 |
-| 3 | 1 T AB 2 8  | 2 F AB 3 6 |
-| 4 | 1 T AB 2 10 | 2 F AB 1 5 |
-
-The Matcher would initiate the following swap:
-
-  - Row 1, To:   Investor 1 trades 1 A token to 4 B tokens
-  - Row 1, From: Investor 2 trades 1 A token from 4 B tokens
-  - Matcher takes 4 B tokens as profit
-
-Row 1 From is not fully realized, table becomes:
-
-|Row| To          | From       |
-|---|-------------|------------|
-| 1 | 1 T AB 6 6  | 2 F AB 1 8 |
-| 2 | 1 T AB 2 8  | 2 F AB 2 7 |
-| 3 | 1 T AB 2 10 | 2 F AB 3 6 |
-| 4 |             | 2 F AB 1 5 |
-
-The Matcher would initiate the following swap:
-
-  - Row 1, To:   Investor 1 trades 1 A token to 6 B tokens
-  - Row 1, From: Investor 2 trades 1 A token from 6 B tokens
-  - Matcher takes 2 B tokens as profit
-
-Row 1 To is now fully realized, table becomes:
-
-|Row| To          | From       |
-|---|-------------|------------|
-| 1 | 1 T AB 5 6  | 2 F AB 2 7 |
-| 2 | 1 T AB 2 8  | 2 F AB 3 5 |
-| 3 | 1 T AB 2 10 | 2 F AB 1 5 |
-
-The Matcher would initiate the following last swap:
-
-  - Row 1, To:   Investor 1 trades 2 A token to 12 B tokens
-  - Row 1, From: Investor 2 trades 2 A token from 12 B tokens
-  - Matcher takes 2 B tokens as profit
-
-Table becomes:
-
-|Row| To          | From       |
-|---|-------------|------------|
-| 1 | 1 T AB 3 6  | 2 F AB 3 5 |
-| 2 | 1 T AB 2 8  | 2 F AB 1 5 |
-| 3 | 1 T AB 2 10 |            |
-
-At this point the lowest To's price is larger than the largest From's price so
-no more swaps would be initiated until new orders came in.
-
-```rust
-pub enum ExchangeInstruction {
-    /// Trade swap request
-    /// key 0 - Signer
-    /// key 1 - Account in which to record the swap
-    /// key 2 - 'To' order

-    /// key 4 - Token account associated with the To Trade
-    /// key 5 - Token account associated with From trade
-    /// key 6 - Token account in which to deposit the Matcher profit from the swap.
-    SwapRequest,
-}
-
-/// Swap accounts are populated with this structure
-pub struct TradeSwapInfo {
-    /// Pair swapped
-    pub pair: TokenPair,
-    /// `To` order
-    pub to_trade_order: Pubkey,
-    /// `From` order
-    pub from_trade_order: Pubkey,
-    /// Number of primary tokens exchanged

-    /// Number of secondary tokens exchanged
-    pub secondary_tokens: u64,
-    /// Price the secondary tokens were exchanged for
-    pub secondary_price: u64,
-}
-```
-
-## Exchange program operations
-
-Putting all the commands together from above, the following operations will be
-supported by the on-chain exchange program:
-
-```rust
-pub enum ExchangeInstruction {
-    /// New token account
-    /// key 0 - Signer
-    /// key 1 - New token account
-    AccountRequest,
-
-    /// Transfer tokens between two accounts
-    /// key 0 - Account to transfer tokens to
-    /// key 1 - Account to transfer tokens from.  This can be the exchange program itself,
-    ///         the exchange has a limitless number of tokens it can transfer.
-    TransferRequest(Token, u64),
-
-    /// order request
-    /// key 0 - Signer
-    /// key 1 - Account in which to record the swap
-    /// key 2 - Token account associated with this trade
-    TradeRequest(TradeRequestInfo),
-
-    /// order cancellation
-    /// key 0 - Signer
-    /// key 1 -order to cancel
-    TradeCancellation,
-
-    /// Trade swap request
-    /// key 0 - Signer
-    /// key 1 - Account in which to record the swap
-    /// key 2 - 'To' order
-    /// key 3 - `From` order
-    /// key 4 - Token account associated with the To Trade
-    /// key 5 - Token account associated with From trade
-    /// key 6 - Token account in which to deposit the Matcher profit from the swap.
-    SwapRequest,
-}
-```
-
-## Quotes and OHLCV
-
-The Matcher will provide current bid/ask price quotes based on trade actively and
-also provide OHLCV based on some time window.  The details of how the bid/ask
-price quotes are calculated are yet to be decided.
-
-## Investor strategies
-
-To make a compelling demo, the investors needs to provide interesting trade
-behavior.  Something as simple as a randomly twiddled baseline would be a
-minimum starting point.
-
-## Running the exchange
-
-The exchange bench posts trades and swaps matches as fast as it can.  
-
-You might want to bump the duration up
-to 60 seconds and the batch size to 1000 for better numbers.  You can modify those
-in client_demo/src/demo.rs::test_exchange_local_cluster.
-
-The following command runs the bench:
-
-```bash
-$ RUST_LOG=solana_bench_exchange=info cargo test --release -- --nocapture test_exchange_local_cluster
-```
-
-To also see the cluster messages:
-
-```bash
-$ RUST_LOG=solana_bench_exchange=info,solana=info cargo test --release -- --nocapture test_exchange_local_cluster
-```

-## Manual Node Setup for Colocated Hardware
-
-This section describes how to set up a new machine that does not have a
-pre-configured image with all the requirements installed.  Used for custom-built
-hardware at a colocation or office facility.  Also works for vanilla Ubuntu cloud
-instances.
-
-### Pre-Requisites
-
- - Install Ubuntu 18.04 LTS Server
- - Log in as a local or remote user with `sudo` privileges
-
-### Install Core Requirements
-
-##### Non-GPU enabled machines
-```bash
-sudo ./setup-new-buildkite-agent/setup-new-machine.sh
-```
-
-##### GPU-enabled machines
- - 1 or more NVIDIA GPUs should be installed in the machine (tested with 2080Ti)
-```bash
-sudo CUDA=1 ./setup-new-buildkite-agent/setup-new-machine.sh
-```
-
-### Configure Node for Buildkite-agent based CI
-
-- Install `buildkite-agent` and set up it user environment with:
-```bash
-sudo ./setup-new-buildkite-agent/setup-buildkite.sh
-```
-- Copy the pubkey contents from `~buildkite-agent/.ssh/id_ecdsa.pub` and
-add the pubkey as an authorized SSH key on github.
-  - In net/scripts/solana-user-authorized_keys.sh
-  - Bug mvines to add it to the "solana-grimes" github user
-- Edit `/etc/buildkite-agent/buildkite-agent.cfg` and/or `/etc/systemd/system/buildkite-agent@*` to the desired configuration of the agent(s)
-- Copy `ejson` keys from another CI node at `/opt/ejson/keys/`
-to the same location on the new node.
-- Start the new agent(s) with `sudo systemctl enable --now buildkite-agent`
-
-# Reference
-
-This section contains details regarding previous CI setups that have been used,
-and that we may return to one day.
-
-## Buildkite Azure Setup
-
-Create a new Azure-based "queue=default" agent by running the following command:
-```
-$ az vm create \
-   --resource-group ci \
-   --name XYZ \
-   --image boilerplate \
-   --admin-username $(whoami) \
-   --ssh-key-value ~/.ssh/id_rsa.pub
-```
-
-The "boilerplate" image contains all the required packages pre-installed so the
-new machine should immediately show up in the Buildkite agent list once it has
-been provisioned and be ready for service.
-
-Creating a "queue=cuda" agent follows the same process but additionally:
-1. Resize the image from the Azure port to include a GPU
-2. Edit the tags field in /etc/buildkite-agent/buildkite-agent.cfg to `tags="queue=cuda,queue=default"`
-   and decrease the value of the priority field by one
-
-### Updating the CI Disk Image
-
-1. Create a new VM Instance as described above
-1. Modify it as required
-1. When ready, ssh into the instance and start a root shell with `sudo -i`.  Then
-   prepare it for deallocation by running:
-   `waagent -deprovision+user; cd /etc; ln -s ../run/systemd/resolve/stub-resolv.conf resolv.conf`
-1. Run `az vm deallocate --resource-group ci --name XYZ`
-1. Run `az vm generalize --resource-group ci --name XYZ`
-1. Run `az image create --resource-group ci --source XYZ --name boilerplate`
-1. Goto the `ci` resource group in the Azure portal and remove all resources
-   with the XYZ name in them

-## Buildkite AWS CloudFormation Setup
-
-**AWS CloudFormation is currently inactive, although it may be restored in the
-future**
-
-AWS CloudFormation can be used to scale machines up and down based on the
-current CI load.  If no machine is currently running it can take up to 60
-seconds to spin up a new instance, please remain calm during this time.
-
-### AMI
-We use a custom AWS AMI built via https://github.com/solana-labs/elastic-ci-stack-for-aws/tree/solana/cuda.
-
-Use the following process to update this AMI as dependencies change:
-```bash
-$ export AWS_ACCESS_KEY_ID=my_access_key
-$ export AWS_SECRET_ACCESS_KEY=my_secret_access_key
-$ git clone https://github.com/solana-labs/elastic-ci-stack-for-aws.git -b solana/cuda
-$ cd elastic-ci-stack-for-aws/
-$ make build
-$ make build-ami
-```
-
-Watch for the *"amazon-ebs: AMI:"* log message to extract the name of the new
-AMI.  For example:
-```
-amazon-ebs: AMI: ami-07118545e8b4ce6dc
-```
-The new AMI should also now be visible in your EC2 Dashboard.  Go to the desired
-AWS CloudFormation stack, update the **ImageId** field to the new AMI id, and
-*apply* the stack changes.

 ## Moving to a newer nightly
 
-NOTE: Follow instructions in docker-rust/README.md before this when updating the stable
-rust version as well.
-
 We pin the version of nightly (see the `ARG nightly=xyz` line in `Dockerfile`)
 to avoid the build breaking at unexpected times, as occasionally nightly will
 introduce breaking changes.
 
 To update the pinned version:
-1. Edit `Dockerfile` to match the desired stable rust version to base on if needed.
 1. Run `ci/docker-rust-nightly/build.sh` to rebuild the nightly image locally,
    or potentially `ci/docker-rust-nightly/build.sh YYYY-MM-DD` if there's a
    specific YYYY-MM-DD that is desired (default is today's build).
-   Check https://rust-lang.github.io/rustup-components-history/ for build
-   status
-1. Update `ci/rust-version.sh` to reflect the new nightly `YYYY-MM-DD`
-1. Run `SOLANA_ALLOCATE_TTY=1 SOLANA_DOCKER_RUN_NOSETUID=1 ci/docker-run.sh --nopull solanalabs/rust-nightly:YYYY-MM-DD ci/test-checks.sh`
-   and `SOLANA_ALLOCATE_TTY=1 SOLANA_DOCKER_RUN_NOSETUID=1 ci/docker-run.sh --nopull solanalabs/rust-nightly:YYYY-MM-DD ci/test-coverage.sh [args]...`
+1. Run `SOLANA_DOCKER_RUN_NOSETUID=1 ci/docker-run.sh --nopull solanalabs/rust-nightly:YYYY-MM-DD ci/test-nightly.sh`
    to confirm the new nightly image builds.  Fix any issues as needed
 1. Run `docker login` to enable pushing images to Docker Hub, if you're authorized.
 1. Run `CI=true ci/docker-rust-nightly/build.sh YYYY-MM-DD` to push the new nightly image to dockerhub.com.
-1. Send a PR with the `ci/rust-version.sh` change and any codebase adjustments needed.
+1. Modify the `solanalabs/rust-nightly:YYYY-MM-DD` reference in `ci/buildkite.yml` from the previous to
+   new *YYYY-MM-DD* value, send a PR with this change and any codebase adjustments needed.
