LaTeX (pronounced "lah-TEK") is an open source document typesetting program. Users write in a markup language to describe how a document looks, then LaTeX applies the formatting based on those commands.
Commonly used when writing journal papers, theses, or dissertations, LaTeX can easily typeset mathematical equations, cross-reference figures, or change formatting from one column to two with a single argument.
Getting Started
You can download and install LaTeX to run on your personal machine, but the easiest way to get up and running quickly is to use a real-time online editor such as Overleaf.
