Free and open source icons set?

Hello, totally new to Grav but here is my question.
Is there a free/open source icons set for Grav existing ?

Many thanks in advance for your answers.

@leo, There is no specific icon set for Grav. Any icon set wil do...

Quark, Quark Open Publishing and shortcode-core happen to use Fontawesome (4.7). So, combinations of these should work together nicely.

Or go one step further into "the open" and start using Fork Awesome.
Read why this fork was created in their ReadMe document.

Many thanks. I could install it very easily and it's great !
