CONCEPTS
Concepts
Theory, principles, and mental models. The "what and why" before the "how."
2 guides
Concept guides build the understanding that makes everything else click. Before you cut a joint, you need to understand why wood moves. Before you choose a finish, you need to understand how finishes work.
These guides explain the principles. No step-by-step instructions — that's what technique guides are for. Concepts give you the mental models that let you troubleshoot problems you've never seen and make decisions the tutorial didn't cover.
