About this Documentation
========================

**Fitzz TeXnik Welt** focuses on maximum readability through modern 
typography using **Fira Sans** and **Fira Code**. While the web documentation 
is optimized with generous line spacing, the EPUB version retains the feel 
of a classic technical manual by using **TeX Gyre** serif fonts.
