The Bug Genie includes a VCS Integration module, which allows you to link your projects in The Bug Genie to a source code repository. This module allows your commits to update issues, as well as access a repository viewer directly from The Bug Genie.
Note that the VCS Integration module does not include any source code handling functionality, it simply integrates with an existing VCS solution, such as github, locally hosted git, svn, mercurial, etc.
Before you can start using the module it must be configured on a per-project basis. Please see the up-to-date documentation, here: http://issues.thebuggenie.com/wiki/VCSIntegration
