Pycharm Django Debug file

Hi,

New to pycharm and python. I've been able to setup debugging in phpstorm before but don't know how I should be doing it in Pycharm.

I have  a working Django web application saved on my machine.

I created a pycharm project from it. 

I made an edit to a file. 

How do I setup my environment to run the program normally and break on file? 

Thanks
