Hey @skivan - I’m guessing it didn’t run the post-install scripts, then?
How to proceed depends on if you want Font Awesome 4 or 5.
If you want Font Awesome 4, I would just run the post-install preset script. In your theme directory, run this command:
./vendor/bin/sage preset
One of the steps when that script runs will ask you if you want to install Font Awesome.
If you want Font Awesome 5, see this thread: How to: Use Font Awesome 5 in your Sage theme,
PS - the other two post-install scripts you may want to run are:
./vendor/bin/sage config
./vendor/bin/sage meta
Those aren’t related to Font Awesome, but help with other theme setup tasks.
