 If you changed nothing more than the config, this should work without any problems.
 Type `git status` to see your changes, if there are any, you can reset them with `git reset --hard`. After that, git pull should be possible.
 
+## Bot only mode (no GUI)
+
+To run only the bot (without GUI), that saves the recieved images and videos into the folder specified in the config you need to run
+
+```bash
+npm run botonly
+```
+in the TeleFrame folder.

 ## Building a TeleFrame
 
 A detailed instruction on how to build your own TeleFrame will follow soon.
