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:
latexfor calling the TexLive compilerlanguage-latexfor syntax highlightingpdf-viewfor viewing the compiled pdf.
Linux
sudo apt install texlive-full
Compile tex documents with
pdflatex [mydocument.tex]
