+
+This repository uses [prek](https://github.com/j178/prek) to run its local quality checks and Git hooks from `.pre-commit-config.yaml`.
+
+```bash
+# Install Python dev tools, including prek
+uv sync --only-group dev
+
+# Install Git hooks in your clone
+uv run prek install
+
+# Run the standard hooks across the repository
+uv run prek run --all-files
+
+# Run the manual hooks when needed
+uv run prek run --all-files --hook-stage manual
