How to install a font?

For this tutorial, Fira Sans is used as an example.

1. Download and unzip the archive with font files.
2. Select all font files (usually .ttf or .otf).
3. Click right and then Install.
4. You have now successfully installed a font!

Alternatively to installing every font you encounter, it is also possible to use a font manager to temporarily (de)install fonts. Good (free) fontmanagers are NexusFont and FontBase.
