 ## Defining JSON user inputs
 
-The simplest way for a user to set up the AFC controller is through a dedicated JSON configuration file, an example can be found [here](https://github.com/LBNL-ETA/AFC/blob/master/afc/resources/config/example_config.json). Here the user is able to adjust model parameters and preferences without any interaction with the Python code. Below is a list of these inputs and their meanings:
