This tutorial will help you download and install fonts listed on the alternative fonts comparison table we published. It means you will practice visiting websites of respective fonts like Carlito's and Liberation's, downloading, extracting, viewing, installing and finally using them on your system. This is hoped to help you increase document compatibility using LibreOffice and beyond. Happy working!
