+Pull Requests
+---
+
+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 cherrypick it. Open a PR to start the review
+process and then jump back to your original branch to keep making progress. Once the commit
+is merged, you can use git-rebase to purge it from your original branch.
+
+```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.
+
+### 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.
+
+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.

+## Metrics Server Maintenance
+Sometimes the dashboard becomes unresponsive. This happens due to glitch in the metrics server.
+The current solution is to reset the metrics server. Use the following steps.
+
+1. The server is hosted in a GCP VM instance. Check if the VM instance is down by trying to SSH
+ into it from the GCP console. The name of the VM is ```metrics-solana-com```.
+2. If the VM is inaccessible, reset it from the GCP console.
+3. Once VM is up (or, was already up), the metrics services can be restarted from build automation.
+    1. Navigate to https://buildkite.com/solana-labs/metrics-dot-solana-dot-com in your web browser
+    2. Click on ```New Build```
+    3. This will show a pop up dialog. Click on ```options``` drop down.
+    4. Type in ```FORCE_START=true``` in ```Environment Variables``` text box.
+    5. Click ```Create Build```
+    6. This will restart the metrics services, and the dashboards should be accessible afterwards.
+
+## Debugging Testnet
+Testnet may exhibit different symptoms of failures. Primary statistics to check are
+1. Rise in Confirmation Time
+2. Nodes are not voting
+3. Panics, and OOM notifications
+
+Check the following if there are any signs of failure.
+1. Did testnet deployment fail?
+    1. View buildkite logs for the last deployment: https://buildkite.com/solana-labs/testnet-management
+    2. Use the relevant branch
+    3. If the deployment failed, look at the build logs. The build artifacts for each remote node is uploaded.
+       It's a good first step to triage from these logs.
+2. You may have to log into remote node if the deployment succeeded, but something failed during runtime.
+    1. Get the private key for the testnet deployment from ```metrics-solana-com``` GCP instance.
+    2. SSH into ```metrics-solana-com``` using GCP console and do the following.
+    ```bash
+    sudo bash
+    cd ~buildkite-agent/.ssh
+    ls
+    ```
+    3. Copy the relevant private key to your local machine
+    4. Find the public IP address of the AWS instance for the remote node using AWS console
+    5. ```ssh -i <private key file> ubuntu@<ip address of remote node>```

 * beta - tracks the largest (and latest) `vX.Y` stabilization branch, more stable.
 * stable - tracks the second largest `vX.Y` stabilization branch, most stable.
 
-## Release Steps
+## Steps to Create a Branch
 
-### Changing channels
+### 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>
+    ```
 
-When cutting a new channel branch these pre-steps are required:
+### Update master branch with the next version
 
-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".
-4. Push the new branch to the solana repository
-3. Update Cargo.toml on master to the next semantic version (e.g. 0.9.0 -> 0.10.0) by running `./scripts/increment-cargo-version.sh`.
-5. Land your Cargo.toml change as a master PR.
+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
+     ```
+1. Rebuild to get an updated version of `Cargo.lock`:
+    ```
+    cargo build
+    ```
+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 'Update Cargo.toml versions from X.Y to X.Y+1'
+    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
+    ```
 
-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".
+## Steps to Create a Release
 
-### Updating channels (i.e. "making a release")
+### Create the Release Tag on GitHub
 
-We use [github's Releases UI](https://github.com/solana-labs/solana/releases) for tagging a release.
+1. Go to [GitHub's Releases UI](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 verion 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. 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. Click "Save Draft", then confirm the release notes look good and the tag name and branch are correct.  Go back into edit the release and click "Publish release" when ready.
 
-1. Go [there ;)](https://github.com/solana-labs/solana/releases).
-2. Click "Draft new release".  The release tag must exactly match the `version` field in `/Cargo.toml` prefixed by `v` (ie, `<branchname>.X`).
-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.
-7. Once the release has been made, update Cargo.toml on release to the next semantic version (e.g. 0.9.0 -> 0.9.1) by running `./scripts/increment-cargo-version.sh patch`.
+### 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
+     ```
+1. Rebuild to get an updated version of `Cargo.lock`:
+    ```
+    cargo build
+    ```
+1. Push all the changed Cargo.toml and Cargo.lock files to the **release branch** with something like:
+    ```
+    git co -b version_update
+    git ls-files -m | xargs git add
+    git commit -m 'Update Cargo.toml versions from X.Y.Z to X.Y.Z+1'
+    git push -u origin version_update
+    ```
+
+### Verify release automation success
+1. 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.  This can take up to 90 minutes after creating the tag.
+1. The `solana-secondary` Buildkite pipeline handles creating the binary tarballs and updated crates.  Look for a job under the tag name of the release: https://buildkite.com/solana-labs/solana-secondary
+1. [Crates.io](https://crates.io/crates/solana) should have an updated Solana version.
+
+### Update documentation
+TODO: Documentation update procedure is WIP as we move to gitbook
+
+Document the new recommended version by updating `book/src/running-archiver.md` and `book/src/validator-testnet.md` on the release (beta) branch to point at the `solana-install` for the upcoming release version.
+
+#### Publish updated Book
+We maintain three copies of the "book" as official documentation:
+
+1) "Book" is the documentation for the latest official release.  This should get manually updated whenever a new release is made.  It is published here:
+https://solana-labs.github.io/book/
+
+2) "Book-edge" tracks the tip of the master branch and updates automatically.
+https://solana-labs.github.io/book-edge/
+
+3) "Book-beta" tracks the tip of the beta branch and updates automatically.
+https://solana-labs.github.io/book-beta/
+
+To manually trigger an update of the "Book", create a new job of the manual-update-book pipeline.
+Set the tag of the latest release as the PUBLISH_BOOK_TAG environment variable.
+```bash
+PUBLISH_BOOK_TAG=v0.16.6
+```
+https://buildkite.com/solana-labs/manual-update-book
+
+### Update software on testnet.solana.com
+
+The testnet running on testnet.solana.com is set to use a fixed release tag
+which is set in the Buildkite testnet-management pipeline.
+This tag needs to be updated and the testnet restarted after a new release
+tag is created.
+
+#### Update testnet schedules
+
+Go to https://buildkite.com/solana-labs and click through: Pipelines ->
+testnet-management -> Pipeline Settings -> Schedules
+Or just click here:
+https://buildkite.com/solana-labs/testnet-management/settings/schedules
+
+There are two scheduled jobs for testnet: a daily restart and an hourly sanity-or-restart. \

+https://buildkite.com/solana-labs/testnet-management/settings/schedules/2a926646-d972-42b5-aeb9-bb6759592a53
+
+On each schedule:
+1.  Set TESTNET_TAG environment variable to the desired release tag.
+    1. Example, TESTNET_TAG=v0.13.2
+1.  Set the Build Branch to the branch that TESTNET_TAG is from.
+    1. Example: v0.13
+
+#### Restart the testnet
+
+Trigger a TESTNET_OP=create-and-start to refresh the cluster with the new version
+
+1.  Go to https://buildkite.com/solana-labs/testnet-management
+2.  Click "New Build" and use the following settings, then click "Create Build"
+    1.  Commit: HEAD
+    1.  Branch: [channel branch as set in the schedules]
+    1.  Environment Variables:
+```
+TESTNET=testnet
+TESTNET_TAG=[same value as used in TESTNET_TAG in the schedules]
+TESTNET_OP=create-and-start

+## 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.
+
+```rust
+/// Supported token types
+pub enum Token {
+    A,
+    B,
+    C,
+    D,
+}
+
+/// Supported token pairs
+pub enum TokenPair {
+    AB,
+    AC,
+    AD,
+    BC,
+    BD,
+    CD,
+}
+
+pub enum ExchangeInstruction {
+    /// New token account
+    /// key 0 - Signer
+    /// key 1 - New token account
+    AccountRequest,
+}
+
+/// Token accounts are populated with this structure
+pub struct TokenAccountInfo {
+    /// Investor who owns this account
+    pub owner: Pubkey,
+    /// Current number of tokens this account holds
+    pub tokens: Tokens,
+}
+```
+
+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 4 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 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,
+}
+
+/// 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
+    pub primary_tokens: u64,
+    /// Price the primary tokens were exchanged for
+    pub primary_price: u64,
+    /// 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
+```
