How to use this

[SomeRandomHEFan]

I'm afraid I simply don't understand the readme's instructions. So much of them is mixed with notes for older versions or specific use cases that I don't get what's actually relevant.

As far as I can tell, the scripts aren't actually part of the release. So I can only assume that I'm supposed to download those separately. But where do I put them? I can't find that information anywhere. And what's this about prerequisites? Do I have to install Python-related stuff or is that only applicable if I don't want to use the browser provided?

Sorry if I sound like an idiot, but I just don't understand the instructions, no matter how often I read through them.
