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.
After installing you need to find TexWorks. This is a LaTeX-editor which we will use to edit latex-files and to process them.
