Most people these days are running Win10. If you are running an older OS, the process is much the same. If you're on Linux or Mac, this guide doesn't incorporate that yet.   This isn't the One Guide to Rule them All, although it may become that eventually: this is merely an amalgamation of a lot of stuff around the forum in one easily-findable place. Hopefully it'll be updated to all the stuff around the forum as I do so (anybody with mod powers is welcome to edit this and add things).
