Here is a small example of how you can use Visual Studio 2015 CE with Gitlab:

1. Create a new project in GitLab and clone it to your local file system. Notice you will need the http link to your project in a later step.
2. Open Visual Studio 2015 CE and create a new project in the cloned directory. VS 2015 CE will automatically detect the git version control.
3. Go to the Team Explorer register tab and follow these steps:
   
   Next open the the Repository Settings by clicking on the combobox in the top area of the register card.
   
   Go to the Remotes section and ente your GitLab projectlink from step 1.
   
   Go to the Changes section and make a comment to the included files.
   
   If all is successfully configured you can now go to the Synchronization section and sync, fetch, pull or push your project.
