To be clear here, I've been looking for books on conceptual engineering or conceptual ethics but since it's a relatively new idea I haven't found really anything on it other than

conceptual engineering and conceptual ethics edited by

Alexis Burgess, Herman Cappelen,

and David Plunkett

Does anyone here know any books or papers that really talk about it?

Should I go about learning as much as I can about natural deduction or just use truth trees? I'm not sure if I should go about knowing how both work or if they're optional as I'm learning philosophy by myself. I can give out more information if needed on what I plan to do in my studies if needed.
