-#### Usage
-Run the following command to decrypt the secrets into the environment:
-```bash
-eval $(ejson2env secrets.ejson)
-```
-
-#### Managing secrets.ejson
-To decrypt `secrets.ejson` for modification, run:
-```bash
-$ ejson decrypt secrets.ejson -o secrets_unencrypted.ejson
-```

-        Steps to add a new feature are outlined below. Note that these steps only cover
-        the process of getting a feature into the core Solana code.
-
-        - For features that are unambiguously good (ie bug fixes), these steps are sufficient.
-
-        - For features that should go up for community vote (ie fee structure changes), more
-        information on the additional steps to follow can be found at:
-        <https://spl.solana.com/feature-proposal#feature-proposal-life-cycle>
-
-        1. Generate a new keypair with `solana-keygen new --outfile feature.json --no-passphrase`
-            - Keypairs should be held by core contributors only. If you're a non-core contirbutor going
-            through these steps, the PR process will facilitate a keypair holder being picked. That
-            person will generate the keypair, provide pubkey for PR, and ultimately enable the feature.
-
-        2. Add a public module for the feature, specifying keypair pubkey as the id with
-        `solana_sdk::declare_id!()` within the module. Additionally, add an entry to `FEATURE_NAMES` map.
-
-        3. Add desired logic to check for and switch on feature availability.

+The goal of these guidelines is to improve developer productivity by allowing developers to
+jump any file in the codebase and not need to adapt to inconsistencies in how the code is
+written. The codebase should appear as if it had been authored by a single developer. If you
+don't agree with a convention, submit a PR patching this document and let's discuss! Once
+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 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.
-
-### The PR / Issue Labels
-Labels make it easier to manage and track PRs / issues.  Below some common labels
-that we use in Solana.  For the complete list of labels, please refer to the
-[label page](https://github.com/solana-labs/solana/issues/labels):
-
-* "feature-gate": when you add a new feature gate or modify the behavior of
-an existing feature gate, please add the "feature-gate" label to your PR.
-New feature gates should also always have a corresponding tracking issue
-(go to "New Issue" -> "Feature Gate Tracker [Get Started](https://github.com/solana-labs/solana/issues/new?assignees=&labels=feature-gate&template=1-feature-gate.yml&title=Feature+Gate%3A+)")
-and should be updated each time the feature is activated on a cluster.
-
-* "automerge": When a PR is labelled with "automerge", the PR will be
-automically merged once CI passes.  In general, this label should only
-be used for small hot-fix (fewer than 100 lines) or automatic generated
-PRs.  If you're uncertain, it's usually the case that the PR is not
-qualified as "automerge".
-
-* "good first issue": If you happen to find an issue that is non-urgent and
-self-contained with moderate scope, you might want to consider attaching
-"good first issue" to it as it might be a good practice for newcomers.
-
-* "rust": this pull request updates Rust code.
-
-* "javascript": this pull request updates Javascript code.
-
-### 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.

+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.
+* pubkey: n. The public key of a Ed25519 key-pair.
+* sigverify: v. To verify a Ed25519 digital signature.
 
-## 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 in 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
 ```
 
-When building the master branch, please make sure you are using the latest stable rust version by running:
-
-```bash
-$ rustup update
-```
-
-When building a specific release branch, you should check the rust version in `ci/rust-version.sh` and if necessary, install that version by running:
-```bash
-$ rustup install VERSION
-```
-Note that if this is not the latest rust version on your machine, cargo commands may require an [override](https://rust-lang.github.io/rustup/overrides.html) in order to use the correct version.
-
-On Linux systems you may need to install libssl-dev, pkg-config, zlib1g-dev, etc.  On Ubuntu:
-
-```bash
-$ sudo apt-get update
-$ sudo apt-get install libssl-dev libudev-dev pkg-config zlib1g-dev llvm clang cmake make
-```
-
-## **2. Download the source code.**
+Now checkout the code from github:
 
 ```bash
 $ git clone https://github.com/solana-labs/solana.git
 $ cd solana
 ```
 
-## **3. Build.**
+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
-$ cargo build
+$ git checkout v0.8.0
 ```
 
-# Testing
+Configuration Setup
+---
 
-**Run the test suite:**
+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.
+
+Developing
+===
+
+Building
+---
+
+Install rustc, cargo and rustfmt:
+
+```bash
+$ curl https://sh.rustup.rs -sSf | sh
+$ source $HOME/.cargo/env
+$ rustup component add rustfmt-preview
+```
+
+If your rustc version is lower than 1.26.1, please update it:
+
+```bash
+$ rustup update
+```
+
+On Linux systems you may need to install libssl-dev, pkg-config, zlib1g-dev, etc.  On Ubuntu:
+
+```bash
+$ sudo apt-get install libssl-dev pkg-config zlib1g-dev
+```
+
+Download the source code:
+
+```bash
+$ git clone https://github.com/solana-labs/solana.git
+$ cd solana

+```
 
-# Benchmarking
+Debugging
+---
 
-First, install the nightly build of rustc. `cargo bench` requires the use of the
-unstable features only available in the nightly build.
+There are some useful debug messages in the code, you can enable them on a per-module and per-level
+basis.  Before running a leader or validator set the normal RUST\_LOG environment variable.
+
+For example, to enable info everywhere and debug only in the solana::banking_stage module:
+
+```bash
+$ export RUST_LOG=info,solana::banking_stage=debug
+```
+
+Generally we are using debug for infrequent debug messages, trace for potentially frequent
+messages and info for performance-related logging.
+
+You can also attach to a running process with GDB.  The leader's process is named
+_solana-fullnode_:
+
+```bash
+$ sudo gdb
+attach <PID>
+set logging on
+thread apply all bt
+```
+
+This will dump all the threads stack traces into gdb.txt

+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).
+4. Push your new branch to solana.git
+5. Land your Carto.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 testnet.solana.com
-See the documentation at https://github.com/solana-labs/cluster-ops/. devnet.solana.com and mainnet-beta.solana.com run stable releases that have been tested on testnet. Do not update devnet or mainnet-beta with a beta release.
+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.

-<a name="process"></a>
-## 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)
