+`just install` installs the backend and frontend dependencies and registers the repository's `pre-commit` hooks, so `git commit` runs the configured lint and test hooks locally.
+
 1. Run `just dev` to start Django, Celery, Postgres, Redis, Qdrant, and Nginx. On the first run Docker builds the app image automatically. After that, `just dev` reuses the existing image so normal restarts are fast. If `.env` is missing, the `just` command copies `.env.example` automatically.
 2. Run `just build` after changing `requirements.txt` or `docker/web/Dockerfile`.
 3. For a fully fresh local stack after schema changes, run `just reset-volumes` before starting the containers again. This drops the Docker-backed Postgres, Redis, and Qdrant state so regenerated migrations apply cleanly.
