+### Updating the contract bindings
+
+To update contract bindings for a new version of the Autonity protocol, add the
+new [AGC](https://github.com/autonity/autonity) version (Git tag or commit ID)
+to `AUTONITY_VERSION`, then generate the contract bindings with `make`:
+
+```console
+echo v0.14.0 > AUTONITY_VERSION
+make
+```
+
+Contract functions are ordered alphabetically in order to produce deterministic
+output. After executing the script against a new version of the code, the diffs
+can be reviewed to determine which methods have been modified, removed or added.
+The generated Python bindings include the contract ABIs as Python dictionaries.
+
+If there is a new contract to include, add a new target to `Makefile` and a new
+factory function to `autonity/factory.py` and `autonity/__init__.py`.

 ### Building and testing
 
+First build the Autonity Go Client:
+
+```sh
+make build/autonity/build/bin/autonity
+```
+
 To launch the tests across all supported Python versions, run:
 
 ```sh
-hatch run test:all
+hatch run test:local
 ```
 
 To limit the tests to a specific Python version, add a
 [`hatch run`](https://hatch.pypa.io/latest/cli/reference/#hatch-run) `+`
 argument:
 
 ```sh
-hatch run +py=3.12 test:all
+hatch run +py=3.12 test:local
