Where is a good tutorial for making maps for Xonotic?

Where could I find decent, up to date tutorials for making maps in Xonotic, preferably videos? I'd like to give it a shot, but I have no clue where to start. I did manage to get the mapping software compiled, but a video tutorial would be lovely.

It's for Alien Arena but also work for Xonotic.

Just push the button in Net-radiant and see what happens. That's how I learnt it
