TYPOlight clean setup

Browsing TYPOlight community forums I have bumped into Ruud’s clean setup tutorial and decided to place it here. The tutorial is pasted as it is in its original state. All credits go to Ruud!
TL comes with the music academy sample installed which for most users is a nice way to get to see how certain things are done. however, most won’t want to start from there. Setting up a clean install everytime is a lot of work as well.
