Nodir, I think you should decide about the license of git-tf -- add a LICENSE.txt and mention it in the documentation.
I suppose it is open source now, but don't know exactly the license it uses. I know of people who don't want to contribute to projects if they don't know the license. Also, there are companies with strict rules for application they can use in development -- depending on the license.
It is better if you do it now than later because -- if you have contributions from many people -- you will have to ask them all if they are OK with the chosen license.
Cheers,

PS. My choice for my opensource projects if the Apache2.0 license. It is a widely used business-friendly liberal open source license.
