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.
