I have collected a list of useful resources for setting up and learning LaTeX here.

Some guides I have written:

- Natural Deduction Proofs in LaTeX: covers Fitch proofs, proof trees, truth trees, and Lemmon proofs.
- Quick TikZ for Modal Logicians: a gentle how-to for creating fancy diagrams in LaTeX. Also, for another great tutorial, check out Justin Khoo’s Causal Modeling Diagrams in TikZ.
- Modal Logic Symbols: a collection of some common (and some uncommon!) modal logic symbols. I’ve collected the commands for these symbols into a package file: modalops.sty. I also defined counterfactual biconditionals, which (as far as I know) are not in any other package.

Packages:

**Fitch Proofs:**fitch (Kluwer, debugged), fitch (Selinger/Zach), or lplfitch.**Proof Trees:**bussproofs**Truth Trees:**qtree sort of works, but TikZ is more flexible.**Diagrams:**TikZ or XY-Pic**Modal Logic Symbols:**modalops.sty
