How to set up a group GitLab repository and use Git

All team members need to have a gitlab(*) account on gitlab.cs.unh.edu. (If you can’t logon, contact support.)

One team member creates a repository (Repositories -> New; initialize with a README and include a .gitignore)
Invite your team mates as follows:

Go to repository -> Settings -> Collaborators
Under “Search by..” enter your team mates GitHub handle and invite.

All team members need to check their email and confirm the invitation within 24h

Now all of you can clone the GitHub repository locally, commit, and push.

Here some Tips on working with Github

Commit often
Give informative commit messages

first line is a summary,
then empty line,
then a list of everything that changed

Make sure your code compiles before committing
Pull often and merge changes
If you are not ready to commit, but you want to pull, use:

git stash
git pull
git stash pop

You will have merge conflicts. Most of those are automatically handled by git. But you need to learn how to use a visual merge tool (e.g., meld, or one that is built into your IDE).

(*) if it says GitHub somewhere, I misspoke and meant to say gitlab.
