Arch based distributions

Debian based distributions
$ apt-get install texlive

Optional
Tectonic
Tectonic is a new self-contained LaTeX engine, meaning it comes with everything you need to compile your documents. Texitor supports Tectonic assuming you have it downloaded and added to your path environment variable. You can download and install Tectonic here. Note that this will simply place an executable in the directory you ran the command from. We recommend adding it to your path environment variable.
Latexmk
Latexmk is included with the recommend TeX distributions we listed however it is required that you have a perl environment to use it. Perl comes with just about every Linux distribution and MacOS. On Windows, we recommend Strawberry Perl.
