+# Watchtower
+
+Automatically updates running Docker containers to the latest image versions.
+
+## Setup
+
+1. Copy `.env.example` to `.env`:
+   ```
+   cp .env.example .env
+   ```
+
+2. Edit `.env` with your SMTP credentials for email notifications.
+
+3. Start:
+   ```
+   docker compose up -d
+   ```
+
+## What to Configure
+
+- **`.env`** — All SMTP settings. Watchtower will send email notifications after updates (or if updates fail).
+- **Schedule** — `WATCHTOWER_SCHEDULE=0 0 4 * * 0` runs every Sunday at 4 AM. Uses 6-field cron. Change as desired.
+- **Docker socket** — Mounts `/var/run/docker.sock`. Required for Watchtower to manage containers.
+- **Cleanup** — `WATCHTOWER_CLEANUP=true` removes old images after updates. Set to `false` if you want to keep them.
+- **Scope labels** — To exclude a container from auto-updates, add `com.centurylinklabs.watchtower.scope=ignore` to its container labels.
