Latex

Installation

No Install

Use Overleaf to create latex documents in a web browser.

Partial Install

Download MikTex. It includes the TeXworks editor and will download packages as you use them. This will not take up as much disk space as a full install.

Full Install

Windows

Download TexLive. This is several gigabytes since it includes all the popular LaTex packages and takes a while to install. You'll also need an editor. I recommend installing Atom with the following packages:

• latex for calling the TexLive compiler
• language-latex for syntax highlighting
• pdf-view for viewing the compiled pdf.

Linux

sudo apt install texlive-full

Compile tex documents with

pdflatex [mydocument.tex]
