The one trick is to make sure your file naming & organization is good. They have good documentation on it. Everything's pretty much automatic then, almost zero further work. The naming conventions aren't too bad, and the resulting file tree would be a reasonable way to organize your files regardless.
I actually like the conventions. Movie name and a year in parentheses and then it can be whatever. E.g.
Movie (2016).whatever.zzz/whatever.mkv
