LaTeX is a great typesetting system that includes a lot of features that allow to produce scientific documents. Many researchers use LaTeX to produce their papers and presentations, and many journals require authors to hand in their articles in a LaTeX format.

Installing a TeX distribution

LaTeX is free to use. To use the LaTeX system, a TeX distribution needs to be installed. Detailed instructions for the different platforms are provided below.

After following the instructions, check whether everything worked by checking the output of the following command:

tex --version

This should give an output similar to this one, where version numbers and details will change depending on your platform.

TeX 3.14159265 (TeX Live 2019/Debian)

For Windows Users

Download the file install-tl-windows.exe from here and follow the instructions.

For Mac Users

We can install this using homebrew:

brew cask install mactex

For Linux Users (Ubuntu-based)

Install it from the terminal using

sudo apt-get install texlive-latex-extra

Note that additional packages for Tex Live should be installed through the apt package manager as well (using tlmgr leads to problems due to different versions)
