Disclaimer: I wrote the packages language-latex2e, autocomplete-latex, latex-wordcount, and hyperclick-latex. I still try to provide a list of all useful packages though, so let me know if I have missed one.

This is a general guide for how to get started with LaTeX in Atom.

NOTE: This guide assumes you already have LaTeX installed on your computer. If you do not, I recommend TeX Live.
