Scenario:
You just downloaded some cool fonts and you want to use them on your presentation at LibreOffice Presentation.
The fonts are some *.ttf files and you don’t know how to use them or where to put them.
Solution:
Create a folder named “.fonts” in your home directory and place the files in there. It is a “hidden”, system folder located in your system account’s home directory.
Open LibreOffice and you are ready!
mkdir ~/.fonts
Enjoy 🙂
