How the frick does it work?

So i've just tried to get forge 1.12.2 for Minecraft. I went to this site and downloaded the version I wanted. But then when I open the files I'm met by this. Pretty much every video or online guide say there's just supposed to be a download screen, not a million documents and coding files. Did I miss something or what? I have literally no idea what to do with this, i've clicked on pretty much everything and still don't have a clue.

So I tried to download forge 1.12.2, but was only met by a whole folder of code and maps. I asked about it here, but was shot down because 1.12.2 isn't supported. So I tried again with the latest version. Still the same. Did I miss something or does my computer just hate me?
