Out of date CSS files?

[paride]

In order to use some recently (and not-so-recently) added icons I tried rebuilding the font from git. I followed the "Build the font in a Docker container" steps from README.md.

The result looks good, for example the "ubuntu" icon is present in the built web fonts:

$ grep ubuntu fonts/forkawesome-webfont.svg
    <glyph glyph-name="ubuntu" unicode="&#xf36f;" horiz-adv-x="1280"

However no file under the scss/ directory has been modified, and indeed no "ubuntu" icon there (grep ubuntu scss/* returns nothing). AIUI that's needed to enable the usage of icons with <i> tags.

Is there an extra step to rebuild the CSS files? If you have a pointer on what commands to run, I'll gladly create a PR to update the build instructions in the README.md.

Thanks!
