IntelliJ does not show project folders

So after asking another question, someone helped me figure out that under File > Project Structure > Modules, there’s supposed to be stuff there. If it’s empty (says “Nothing to show”), do the following:

1. In File > Project Structure > Modules, click the “+” button,
2. Press Enter (because weirdly it won’t let me click on “New Module”)
   
3. In the window that pops up, click on the “…” next button which takes you to the Content root. Find your root folder and select it
   
4. Click the “ok” button
5. Ignore any warning that says the name is already in use
