I'm following the Udemy Haskell course, which at some point showed that Haskell is loading using the Stack option. I configured my $ PATH and installed the stack when I had a problem.

But then again, I don’t know what to do with it. Sorry if my question is basic, but I haven’t done anything like this before, and what I found on the Internet was hard to interpret how it applies to my situation.
Any help would be greatly appreciated. 😀
