 Unlike the use of ROS 2 `.msg` files, since Ardupilot supports native DDS, the message files follow [OMG IDL DDS v4.2](https://www.omg.org/spec/IDL/4.2/PDF).
 This package is intended to work with any `.idl` file complying with those extensions.

+### Development Requirements
+
+Astyle is used to format the C++ code in AP_DDS. This is required for CI to pass the build.
+See [Tools/CodeStyle/ardupilot-astyle.sh](../../Tools/CodeStyle/ardupilot-astyle.sh).
+
+```console
+./Tools/CodeStyle/ardupilot-astyle.sh libraries/AP_DDS/*.h libraries/AP_DDS/*.cpp
+```
+
+Pre-commit is used for other things like formatting python and XML code. 
+This will run the tools automatically when you commit. If there are changes, just add them back your staging index and commit again.
+
+1. Install [pre-commit](https://pre-commit.com/#installation) python package.
+1. Install ArduPilot's hooks in the root of the repo, then commit like normal
+  ```console
+  cd ardupilot
+  pre-commit install
+  git commit
+  ```
