[malcheyne]

In the README.md the Font-Awesome links have the 404 error page.

On the Font-Awesome Github page says they've updated to 6 and think you running off 4.

"Where did Font Awesome 5, 4 (or 3) go?

Now that Font Awesome 6 has been released we are marking version 5 as Long Term Suport (LTS). Version 5 will get critical bug fixes only. Version 3 and 4 are now end-of-life and we don't plan on releasing any further versions of the 4.x or 3.x."
