You're kidding, right?

Lil Boxes is still in early beta (you might even say it isn't out of alpha). You honestly think there's going to be any Frequently Asked Questions? Who would be asking these questions? Think about it before you start clicking links all willy-nilly! Now get outta here and go use Lil Boxes. Then come back with your questions so we can add them here.

How much does it cost?

Nothing, its open source. Download it and use it as you please.

Is it licensed?

Yes, under MIT licensing
