Learning to use GCA4 (building templates)

[oma]

Edit: Searched and found my answers I think. Pay no attention. Move along folks, there's nothing to see here.

I am now ready to start using GCA4 and learning it well. I want to build templates for my players. I tried one, but didn't understand very well about what I was doing and found that I do not know how to load it up to see what it looks like on an actual character.

How do I load it into the program so it is selectable from the list of TEMPLATES in GCA4?

Also, is there a place to go to learn basic info about how GCA works and how to build templates, what the CATEGORIES is for and how to use those tags?

Thank
