+This project uses [the `pre-commit` tool](https://pre-commit.com/) for linting the JSON files and ensuring consistent formatting. It can be installed with `pip`:
+```bash
+pip install pre-commit
+pre-commit --version
+```
+
+The `pre-commit` tool hooks into Git's commit machinery to run a set of linters and static analyzers over each change. To install `pre-commit` into Git's hooks, run:
+```bash
+pre-commit install
+```
+
+To uninstall `pre-commit`, run either `pre-commit uninstall` or `rm .git/hooks/pre-commit`.
