Template code for Pycharm plugin Follow

Hi all, 

I want to build a simple plugin for pycharm. 

Where can I find a simple template code for the plugin. 

The goal is to add an action to Run menu that execute, the runfile('/select_file.py') in python console. 
The action is like Execute line in console, but instead of execute the line, execute runfile function

Where can I find the action documentation for this?
