For some time now I've been wondering whether I could create a custom template for the Latex Beamer class for my own presentations and how hard it would be. The problem is I can't seem to find any introductory material on how to get started. Does someone have some introductory material on the topic?
Everything you need is somewhere in here: Beamer User Guide
I'd recommend starting with a ready made template and tweaking it, rather than starting from scratch first time out...
