LaTeX is installed by installing a distribution. A distribution is a collection of packages and programs. We recommend the following distributions:
TeX Live. On Linux you can also use a package manager; e.g. in Ubuntu you can use the command
sudo apt-get install texlive. TeX Live also contains TeXworks, the editor we will use throughout this course.
MacTeX. This is the Mac version of TeX Live.
After installing you need to find TexWorks (it is part of the TeXLive installation). This is a LaTeX-editor which we will use to edit latex-files and to process them.
