As a note, the example command lines didn't have "$" or "#" at the start of them, to make it 100% clear they're commands people type in. I've added those in where I think it's correct, plus added in "sudo" before super user commands (ie yum), where it seems to be correct. Probably a good idea for you to check things are still all correct, just to be safe. :) Regards and best wishes, Justin Clift
