## What it is
Source Serif is an open-source serif typeface family designed by Adobe to complement Source Sans, available in many sizes, weights, and languages including variable font formats. The repository contains font source files and build instructions using AFDKO.

## When to choose
- you need a freely licensed (OFL) serif typeface for print or web
- you want optical sizes and many weights in one variable font
- you need broad language support in a text font
