@@ -59,52 +59,105 @@ There are three release channels that map to branches as follows:
 * 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
 
-### Advance the Channels
-
-#### Create the new branch
-1. Pick your branch point for release on master.
-1. Create the branch.  The name should be "v" + the first 2 "version" fields
+### 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.  Note the Cargo.toml in the repo root directory does not contain a version.  Look at any other Cargo.toml file.
-1. Create a new branch and push this branch to the solana repository.
-    1. `git checkout -b <branchname>`
-    1. `git push -u origin <branchname>`
+1. Create the new branch and push this branch to the `solana` repository:
+    ```
+    git checkout -b <branchname>
+    git push -u origin <branchname>
+    ```
 
-#### Update master with the next version
+### Update master branch with the next version
 
-1. After the new branch has been created and pushed, 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
-   `cargo build` to cause a refresh of `Cargo.lock`.
-1. Push your Cargo.toml change and the autogenerated Cargo.lock changes to the
-   master branch
+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
 
-### Make the 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 [there ;)](https://github.com/solana-labs/solana/releases).
+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` (ie, `<branchname>.X`).
+   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)
-   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.
-1. Once the release has been made, update Cargo.toml on the release branch to the next
-   semantic version (e.g. 0.9.0 -> 0.9.1) by running
-   `./scripts/increment-cargo-version.sh patch`, then rebuild with `cargo
-   build` to cause a refresh of `Cargo.lock`.
-1. Push your Cargo.toml change and the autogenerated Cargo.lock changes to the
-   release branch.
+   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
+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
+```

+- Order side
+  - Describes which side of the market an investor wants to place a trade on. Options

-- Trade request
-  - A Solana transaction executed by the exchange requesting the trade of one
-    type of token for another.  Trade requests are made up of the token pair,
-    the direction of the trade, 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
