 # XtendR
 
-A python 3 extension system to ease the use of plugins.
+A very basic Python 3.12 plugin system based on the K.I.S.S principle.
+
+I was in need of a new plugin system, which should meet these requirements:  
+:heavy_plus_sign: Simple to use  
+:heavy_plus_sign: Work well with Python 3.12  
+:heavy_plus_sign: Maintainable - Don't expect to see new releases every month. __If it ain't broken, don't fix it!!!__
+
+I previously used yapsy, but it doesn't meet the requirements anymore.  
+:x: No longer simple, and simple to use (Simplicity in use has been sacrificed for more complexity. It has become bloated)  
+:x: Not workink with Python 3.12  
+:x: No longer maintained (Hasn't been maintained for a few years)
+
+I didn't find anything that suited my needs, so I decided to make my own plugin system.  
+It simply contains 2 classes, one for the plugin system and one abstraction base class for the plugins themselves.
+
+At the moment only 4 functions are available:
+- Attach
+- Run
+- Stop
+- Detach
+
+Attach and Detach are used for registrering/unregistrering a module on the system.
+The Run and Stop functions are mandatory in the plugin modules.
+
+The system expects a folder called 'plugins', placed at the root, along side your main python file.
+Each plugin should be placed in subfolders, named as the plugin, inside the 'plugins' folder.
+
+The example.py along with the plugins/example_plugin/example_plugin.py and plugins/example_plugin/example_plugin.json shows the workings of this plugin system.
