I've downloaded a project from github, and am trying to figure out how to setup Pycharm to know where the files are, and what functions are located in them. I've worked with IDE's before that when right-clicking a function, show what file it originates from and what line. Currently, there are a bunch of errors highlighted because the PythonPath is not setup correctly in the IDE. How can I set up something like this in the Pycharm Community Edition? Any suggestions are appreciated.
