-### Release
+## PR process

-1. Ensure that all tests passed on the last CI that ran on `main`.
+- [ ] Your changes should be on a branch.
+- [ ] Your changes should have unit tests.
+- [ ] Lint the code with `npm lint`
+- [ ] Build your code with `npm build`
+- [ ] Run the unit tests with `npm test`
+- [ ] Get a full code review.
+- [ ] Merge your branch into `main` and push to github.
+- [ ] Ensure that all tests passed on the last CI that ran on `main`.

-NOW WE ARE READY TO PUBLISH! No new code changes happen manually now.
+## Release

-2. Checkout `main` (or your beta branch) and `git pull`.
-3. Create a new branch (`git checkout -b <BRANCH_NAME>`) to capture updates that take place during this process.
-4. Update `HISTORY.md` to reflect release changes.
-5. Run `npm run docgen` if the docs were modified in this release to update them (skip this step for a beta).
-6. Run `npm run build` to triple check the build still works
-7. Run `npx lerna version --no-git-tag-version` - This creates a draft PR and bumps the versions of the packages.
-  * For each changed package, pick what the new version should be. Lerna will bump the versions, commit version bumps to `main`, and create a new git tag for each published package.
-  * If publishing a beta, make sure that the versions are all of the form `a.b.c-beta.d`, where `a`, `b`, and `c` are identical to the last normal release except for one, which has been incremented by 1.
-8. Run `npm i` to update the package-lock with the updated versions
-9. Create a new PR from this branch into `main` and merge it (you can directly merge into the beta branch for a beta).
-10. Checkout `main` and `git pull` (you can skip this step for a beta since you already have the latest version of the beta branch).
-11. Run `npx lerna publish from-package --yes` - This will actually publish the packages.
-  * NOTE: if you're releasing a beta, run `npx lerna publish from-package --dist-tag beta --yes` instead.
-  * If it asks for it, enter your [npmjs.com](https://npmjs.com) OTP (one-time password) to complete publication.
-12. Create a new branch (`git checkout -b <BRANCH_NAME>`)to capture the updated packages from the release. Merge those changes into `main`. (You can skip this step on a beta release).
+1. Checkout `main` (or your beta branch) and `git pull`.
+1. Create a new branch (`git checkout -b <BRANCH_NAME>`) to capture updates that take place during this process.
+1. Update `HISTORY.md` to reflect release changes.

-NOW YOU HAVE PUBLISHED! But you're not done; we have to notify people!
+   - [ ] Update the version number and release date, and ensure it lists the changes since the previous release.

-13. Pull the most recent changes to main locally.
-14. Run `git tag <tagname> -m <tagname>`, where `<tagname>` is the new package and version (e.g. `xrpl@2.1.1`), for each version released.
-15. Run `git push --follow-tags`, to push the tags to Github.
-16. On Github, click the "releases" link on the right-hand side of the page.
-17. Click "Draft a new release"
-18. Click "Choose a tag", and choose a tag that you just created.
-19. Edit the name of the release to match the tag (IE \<package\>@\<version\>) and edit the description as you see fit.
-20. Repeat steps 17-19 for each release.
-21. Send an email to [xrpl-announce](https://groups.google.com/g/xrpl-announce).

+1. Checkout `main` and `git pull` (you can skip this step for a beta since you already have the latest version of the beta branch).
+1. Actually publish the packages with one of the following:
+
+   - Stable release: Run `npx lerna publish from-package --yes`
+   - Beta release: Run `npx lerna publish from-package --dist-tag beta --yes`  
+     Notice this allows developers to install the package with `npm add xrpl@beta`
+
+1. If requested, enter your [npmjs.com](https://npmjs.com) OTP (one-time password) to complete publication.
+1. If not a beta release: Create a new branch (`git checkout -b <BRANCH_NAME>`) to capture the updated packages from the release. Merge those changes into `main`.
+
+   NOW YOU HAVE PUBLISHED! But you're not done; we have to notify people!
+
+1. Pull the most recent changes to `main` locally.

+1. Run `git push --follow-tags`, to push the tags to Github.
+1. On GitHub, click the "Releases" link on the right-hand side of the page.
+
+1. Repeat for each release:
+
+   1. Click "Draft a new release"
+   1. Click "Choose a tag", and choose a tag that you just created.
+   1. Edit the name of the release to match the tag (IE \<package\>@\<version\>) and edit the description as you see fit.
+
+1. Lastly, send an email to [xrpl-announce](https://groups.google.com/g/xrpl-announce).
+
+# ripple-lib 1.x releases
+
+- [ ] Publish the release to npm.
+
+  - [ ] If you are publishing a 1.x release to the `xrpl` package, use:
+
+        npm publish --tag ripple-lib
+
+    This prevents the release from taking the `latest` tag.
+
+For ripple-lib:
+
+ - Have one of the ripple-lib package maintainers push to `ripple-lib` (npm package name). You can contact [@intelliot](https://github.com/intelliot) to request the npm publish.
+- For ripple-lib releases, cross-publish the package to `xrpl` with `--tag ripple-lib`
+  - [Here's why](https://blog.greenkeeper.io/one-simple-trick-for-javascript-package-maintainers-to-avoid-breaking-their-user-s-software-and-to-6edf06dc5617).

 # Definitions

+This file is used to serialize/deserialize transactions and ledger objects for the XRPL. It's broken into 5 sections laid out below.
+
+At the bottom of this README you can find instructions and examples for how to define your own types in a definitions file in order to work on a custom sidechain or develop new amendments.
+
 ## Types

 These are the [types](https://xrpl.org/serialization.html#type-list) associated with a given Serialization Field. Each type has an arbitrary [type_code](https://xrpl.org/serialization.html#type-codes), with lower codes sorting first.
@@ -53,8 +57,88 @@ See:
 - https://github.com/ripple/rippled/blob/develop/src/ripple/protocol/TER.h
 - https://xrpl.org/transaction-results.html

-TODO: Write a script to read rippled's source file and generate the necessary mapping.
+To generate a new definitions file from rippled source code, use this tool: https://github.com/RichardAH/xrpl-codec-gen

 ## Transaction Types

 See https://github.com/ripple/rippled/blob/develop/src/ripple/protocol/TxFormats.h
+
+# Defining Your Own Definitions
+
+If you're building your own sidechain or writing an amendment for the XRPL, you may need to create new XRPL definitions.
+
+To do that there are a couple things you need to do:
+
+1. Generate your own `definitions.json` file from rippled source code using [this tool](https://github.com/RichardAH/xrpl-codec-gen) (The default `definitions.json` for mainnet can be found [here](https://github.com/XRPLF/xrpl.js/blob/main/packages/ripple-binary-codec/src/enums/definitions.json))
+2. Create new SerializedType classes for any new Types (So that encode/decode behavior is defined). The SerializedType classes correspond to "ST..." classes in Rippled. Note: This is very rarely required.
+
+- For examples of how to implement that you can look at objects in the [`types` folder](../types/), such as `Amount`, `UInt8`, or `STArray`.
+
+3. Import your `definitions.json` file to construct your own `XrplDefinitions` object.
+4. Pass the `XrplDefinitions` object whenever you `encode` or `decode` a transaction.
+5. If you added any new transaction types, you should create an `interface` for the transaction that extends `BaseTransaction` from the `xrpl` repo to use it with the functions on `Client` (See the below example of adding a new transaction type)
+
+## Example of adding a new Transaction type
+
+```
+// newDefinitionsJson is where you can import your custom defined definitions.json file
+const newDefinitionsJson = require('./new-transaction-type-definitions.json')
+const { XrplDefinitions, Client } = require('xrpl')
+
+const newDefs = new XrplDefinitions(newDefinitionsJson)
+
+// Change to point at the server you care about
+const serverAddress = 'wss://s.devnet.rippletest.net:51233'
+const client = new Client(serverAddress)
+const wallet1 = await client.fundWallet()
+
+// Extending BaseTransaction allows typescript to recognize this as a transaction type
+interface NewTx extends BaseTransaction {
+    Amount: Amount
+}
+
+const tx: NewTx = {
+    // The TransactionType here needs to match what you added in your newDefinitionsJson file
+    TransactionType: 'NewTx',
+    Account: wallet1.address,
+    Amount: '100',
+}
+
+// By passing in your newDefs, your new transaction should be serializable.
+// Rippled will still throw an error though if it's not a supported transaction type.
+const result = await client.submitAndWait(tx, {
+    wallet: wallet1,
+    definitions: newDefs,
+})
+```
+
+## Example of adding a new serializable Type
+
+```
+const { XrplDefinitions } = require('../dist/coretypes')
+
+// newDefinitionsJson is where you can import your custom defined definitions.json file
+const newDefinitionsJson = require('./fixtures/new-definitions.json')
+
+
+// For any new Types you create, you'll need to make a class with the same name which extends a SerializedType object
+// In order to define how to serialize/deserialize that field. Here we simply make our NewType act like a UInt32.
+
+const { UInt32 } = require('../dist/types/uint-32')
+class NewType extends UInt32 {
+  // Should be the same as UInt32
+}
+
+const extendedCoreTypes = { NewType }
+
+const newDefs = new XrplDefinitions(newDefinitionsJson, extendedCoreTypes)
+
+// From this point on, we should be able to serialize / deserialize Transactions with fields that have 'NewType' as their Type.
+
+const encoded = encode(my_tx, newDefs)
+const decoded = decode(encoded, newDefs)
+```
+
+## Other examples
+
+You can find other examples of how to modify `definitions.json` in `definition.test.js` which contains tests for this feature, and uses various example modified `definition` files. You can find the tests and the corresponding example `definition` files in [this folder of test cases](https://github.com/XRPLF/xrpl.js/tree/main/packages/ripple-binary-codec/test)
