There will deffo be a lesson on how to setup a decomp project from scratch! This is far from finished, there's opportunity to add so much more. I'd argue that I'd rather teach the user the basics of matching first before diving into setting a project, as setting up the splits.txt or symbols.txt might be quite a leap for a beginner. Feel free to keep checking in once a week and the lesson will appear :)

I've honestly think "beginner" is the wrong target anyway. If you're interested in contributing to a decomp, assembly basics are table stakes. Focus on the things that someone who already knows assembly won't just know.
