Looking for some easy to follow FormZ tutorials

A project involving building a house in FormZ is coming up, and I’m grossly unprepared. I think I get the basic controls, but are there any clear tutorials (video, text, or otherwise) on really going into making structures? Greatly appreciated.

Founded in 2004, Leakfree.org became one of the first online communities dedicated to Valve’s Source engine development. It is more famously known for the formation of Black Mesa: Source under the 'Leakfree Modification Team' handle in September 2004.
