 # The Python Banyan Framework
-![](https://github.com/MrYsLab/python_banyan/blob/master/images/BanyanTree.png)
 
 
 The Python Banyan Framework is a lightweight, reactive framework used to
 create flexible, non-blocking, event driven, asynchronous applications.
-It was designed primarily to aid in the implementation of real-time physical computing applications
- for devices such as
- the Raspberry Pi, ESP8266,  and Arduino,
-but may easily be applied to projects outside of the physical programming domain.
+
+Python Banyan comes with [full documentation](https://mryslab.github.io/python_banyan/#)
+ that includes a [User's Guide](https://mryslab.github.io/python_banyan/#users_guide/) 
+ with hands-on examples, as well documentation for the
+ [OneGPIO Project](https://mryslab.github.io/python_banyan/#gpio_intro/) 
+ that allows you to quickly and easily build reusable GPIO projects for the
+ Arduino, ESP-8266, and Raspberry Pi.
 
 It is being used by [Palace Games](https://www.raspberrypi.org/blog/raspberry-pi-escape-room/)
 to concurrently monitor hundreds of real-time sensors and actuators.
