Abstract
This guide would be a low level intro to the tools offered by the FEL, targeted for an audience that frequent a high school, a professional school, or Technical schools (e.g. Istituti professionali in Italy). As there are already many good manuals online that explain the various tools, the goal is to explain in a compendium what do the various tools, how to use them using the GUI or the terminal command, when it can offer more configuration/setting options, with simple examples.
