Please open the GIT manager.Then choose the action 'Publish repository'.
This point of the 'GIT manager' helps to create the Public repository. Developers of GIT offer to use some intermediate ("public") repository for synchronisation of changes of the project with other developers. Because giving direct access to your working repository is considered not safe and consequently not correct. This command is launching two subcommands - creation of a repository and a "PULL changes" command.
The first window of wizard suggests to choose branches which you wish to place in a repository.

Further it is necessary to type a name of a new Remote and a path to creating a new repository. It can be a local way or URL with "ssh://" protocol. (For example ssh://git@test.example.com/myRepo.git). In the second case it would be necessary that on a remote computer was instaled GIT and SSH SHH.
