Making Font Awesome Work Within Rails 5

The easiest way to get Font Awesome to work is to use the CDN itself, which requires you to give them your email address.

But there may be times when you want to host it yourself. You can either use a gem, or if you prefer to have more control, you can download the zip from Font Awesome directly.

If you did the latter:

Restart your Rails server if needed. This should now work and you should no longer see any more RoutingError in your logs when the application is trying to find the font file.
