 **Update automatically:**
 
-  1. Use [AppImageUpdate](https://github.com/AppImageCommunity/AppImageUpdate) which reads the update information in the AppImage. This is a low level tool.
-  2. Use a higher level tool that uses AppImageUpdate, like [AM](https://github.com/ivan-hc/AM) or [appimaged](https://github.com/probonopd/go-appimage/blob/master/src/appimaged/README.md) daemon, these tools also automatically handle desktop integration.
