-This should almost always be done using the [`xrpl-codec-gen`](https://github.com/RichardAH/xrpl-codec-gen) script - if the output needs manual intervention afterwards, consider updating the script instead.
+To update just the `definitions.json` file:
+```bash
+poetry run poe definitions https://github.com/XRPLF/rippled/tree/develop
+```

+Any Github branch link or local path to rippled will work here.
 
-1. Clone / pull the latest changes from [rippled](https://github.com/XRPLF/rippled) - Specifically the `develop` branch is usually the right one.
-2. Clone / pull the latest changes from [`xrpl-codec-gen`](https://github.com/RichardAH/xrpl-codec-gen)
-3. From the `xrpl-codec-gen` tool, follow the steps in the `README.md` to generate a new `definitions.json` file.
-4. Replace the `definitions.json` file in the `ripple-binary-codec` with the newly generated file.
-5. Verify that the changes make sense by inspection before submitting, as there may be updates required for the `xrpl-codec-gen` tool depending on the latest amendments we're updating to match.
+To update the models as well:
+```bash
+poetry run poe generate https://github.com/XRPLF/rippled/tree/develop
