## What it is
Source Han Serif is a set of open-source Pan-CJK OpenType serif fonts covering Simplified Chinese, Traditional Chinese, Japanese, and Korean, available in OTF, OTC, subset, and variable font formats. The repository also includes all source files needed to rebuild the fonts with the Adobe Font Development Kit for OpenType (AFDKO).

## Use cases
- find a free CJK serif font for Chinese, Japanese, and Korean text
- download open-source Pan-CJK fonts for a document or website
- get variable font versions of Source Han Serif
- rebuild CJK fonts from source using AFDKO
- use a free alternative to commercial Mincho/Myeongjo fonts
- embed open-licensed CJK fonts in an application

## When to choose
- you need high-quality, freely licensed serif fonts covering all major CJK languages
- you want variable or subset font configurations for web or app deployment
- you need to customize or rebuild the fonts from source

## When to avoid
- you need a sans-serif (gothic) CJK typeface instead of serif
- you need fonts for Latin-only or non-CJK scripts
- you need a font library or rendering engine rather than font files
