-## 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>```
-    6. The logs are in ```~solana\solana``` folder

 * 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
+## Release Steps
 
-### 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
+### Changing channels
+
+When cutting a new channel branch these pre-steps are required:
+
+1. Pick your branch point for release on master.
+1. 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".
-1. Create the new branch and push this branch to the `solana` repository:
-    ```
-    git checkout -b <branchname>
-    git push -u origin <branchname>
-    ```
+1. Push the new branch to the solana repository
+1. 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`, then rebuild with a
+   `cargo build --all` to cause a refresh of `Cargo.lock`.
+1. Push your Cargo.toml change and the autogenerated Cargo.lock changes to the
+   master branch
 
-### Update master branch with the next version
+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".
 
-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
-    ```
+### Updating channels (i.e. "making a release")
 
-## Steps to Create a Release
+We use [github's Releases UI](https://github.com/solana-labs/solana/releases) for tagging a release.
 
-### Create the Release Tag on GitHub
-
-1. Go to [GitHub's Releases UI](https://github.com/solana-labs/solana/releases) for tagging a release.
+1. Go [there ;)](https://github.com/solana-labs/solana/releases).
 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.
-
-### 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
+   field in `/Cargo.toml` prefixed by `v` (ie, `<branchname>.X`).
+1. 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.
+1. Test the release by generating a tag using semver's rules.  First try at a
+   release should be `<branchname>.X-rc.0`.
+1. Verify release automation:
    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-replicator.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/0efd7856-7143-4713-8817-47e6bdb05387
-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
-```
-
-### Alert the community
-
-Notify Discord users on #validator-support that a new release for
-testnet.solana.com is available
+   1. ...
+1. 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.
+1. 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`, then rebuild with a `cargo
+   build --all` to cause a refresh of `Cargo.lock`.
+1. Push your Cargo.toml change and the autogenerated Cargo.lock changes to the
+   release branch

-## 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
-```
