debugging remote django application

I'm new to django. I inherit this project sitting on redhat running apache and django. I need to be able to debug it. From what i read, pycharm can directly debug the code remotely. My question is, how to do that?

do i
1. create local django project
2. copy all the files to my local laptop
3.  setup remote debuggin?

could someone help. i spent hours googling, and i'm still not sure how to do this.
