+# StarrScripts
+
+Bash and Python utility scripts for Starr apps (Radarr, Sonarr, Lidarr, Readarr).
+
+## Structure
+- `servarr/` — Shared Starr app utilities
+- Root scripts — Individual automation tools (backup, dedup, update, etc.)
+
+## Conventions
+- Bash scripts use `.sh` extension
+- Python scripts use `.py` extension
+- All scripts should be POSIX-compatible where possible
+- Use `.env.sample` as template for required environment variables
+
+## Pre-commit
+Pre-commit hooks configured via `.pre-commit-config.yaml`. Run `pre-commit run --all-files` before committing.
