Anyone who's switched (or tried to switch) from Windows® to Linux knows that it's a steep learning curve. I often found myself forgetting how to do certain things, usually from banging my head into the wall so many times, that I decided to start writing them down.
Those notes eventually became the tutorials you see below, I still use them, and published them in the hope they're useful to others too.
