 """
 Simple file watcher using stat() instead of watchdog (no external deps).
-Watches core/ and app/ for changes and restarts ur_gia.
+
+This lightweight watcher can be used when you don't want the `watchdog`
+dependency. Configure the directories to watch using the `WATCH_PATHS`
+environment variable (comma-separated). Configure which container to restart
+using `TARGET_CONTAINER` (defaults to `ur_gia`).
+
+Example:
+
+    WATCH_PATHS=/code/core TARGET_CONTAINER=ur_gia
+
+Touching a file under the watched path will trigger a restart of the target
+container; e.g. `touch /code/core/__restart__` will cause the watcher to act.
