I was initially planning to make this a little workshop, where I would step by step go through the sections of the theme template. But I'm a little short on time at the moment, so for now I will focus on answering questions. Hopefully this can serve as a reference for some proper documentation in the future, but for now the templates are still a bit volatile, so I do not suggest to move information from this thread to a static place.

If you'd like to have a section of the template explained or clarified, please post a screenshot, ideally with arrows and labels describing exactly what you want to know. Especially in the beginning, it is perfectly okay if your questions are very vague though (e.g. "what is all that stuff in that area").

I cannot explain details of the Icons template yet, but as I do some work on Theme Maker, I hope to make that one easier to understand too.
