 # rules_typst
 
 Bazel rules for [Typst](https://typst.app/).
+
+## Development
+
+### Pre-commit hooks
+
+This repo uses [pre-commit](https://pre-commit.com/) to run [buildifier](https://github.com/bazelbuild/buildtools/tree/master/buildifier) for formatting and linting Bazel files.
+
+```sh
+pip install pre-commit
+pre-commit install
+```
+
+To manually run against all files:
+
+```sh
+pre-commit run --all-files
+```
