Welcome to the first set of lessons.  This first video introduces the tutorial series and GHS in general.  We provide an overview of the course, and an introduction to GHS.  GHS is a very flexible program, allowing customized templates.  But the program has several quirk and procedures that are not intuitive.  For example, the introduction video covers the following non-intuitive items.

• Knowledge resources are distributed across multiple locations.
• The commands change, depending if you use an American or European coordinate system.
• Several other items that are revealed in future videos.
