Roboto and PT Sans are not available on gh-pages branch

If I understand the README.md correct, they should be available.

Yup, came to report the same thing. The actual font names that are available are listed here:

If you build from the master branch, the Noto Sans fonts don't have the "Klokantech" prefix .. should gh-pages be updated?
