I second this: Command-line and text files are more user friendly than it seems. 1/ You can search for stuff on the internet and get quick results (not a video) 2/ You can _paste_ a command and send it to someone to run it instead of a word document with instructions and screenshots. 3/ Once you learn to find and search for stuff in files, it is easy to discover where stuff is configured. 4/ Manual pages are great once you know how to read (I mean skim) them.
