+# Wallpaper Watcher Daemon
+
+Run a script whenever your wallpaper changes.
+
+## What it does
+
+This daemon monitors wallpaper changes and executes a script you specify. The new wallpaper path gets passed as the first argument to your script.
+
+## Setup
+
+1. Enable the plugin in Settings → Plugins
+2. Configure the script path in the plugin settings
+3. Make sure your script is executable (`chmod +x /path/to/script.sh`)
+
+## Example script
+
+```bash
+#!/bin/bash
+echo "New wallpaper: $1"
+# Do something with the wallpaper path
+```
+
+Save this to a file, make it executable, and point the plugin to it.
+
+## Use cases
+
+- Generate color schemes from the new wallpaper
+- Update theme files based on wallpaper colors
+- Send notifications when wallpaper changes
+- Sync wallpaper info to other devices
+- Log wallpaper history
+
+## Notes
+
+- Script errors show up as toast notifications
+- Script output goes to console logs
