Registration for foreignes in Goergia

Hello!

I need to know what its proccedure for registration in Georgia.
How long it takes to get registration in practice, and whats law says about it.

Im coming to Georgia in June, for 2 weeks - there is no need to be registred for that short stay but i would like to obtain Georgian driving licence in that time. Ive heard thats its easy and can be done in one day if youre registred in Georgia.

any info  is welcomed
