+## How to develop a new plugin
+
+All plugins are in the folder `/home/pi/craftbeerp3/modules/plugins`.
+Each folder is an own plugin.
+
+If you like to create a new plugin just create a new folder under `/home/pi/craftbeerp3/modules/plugins`
+Inside this folder create an new file called `__init__.py`. This is the entry point for your code.
+Inside of this file place your code.
+
