+
+ - 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.

 # 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.
 
 ## Ledger Entry Types
 
-Each ledger's state tree contain [ledger objects](https://xrpl.org/ledger-object-types.html), which represent all settings, balances, and relationships in the shared ledger.

 - 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)
