Project Workflow

  • Fork the repo.
  • Clone that fork to a local repository.
  • Add the repo as remote to your local clone (e.g. as main).

  • Your main branch is main/your.name, you’ll share your solutions as MRs to this branch:

    • Create a branch and add commits there. Push this branch to remote: 
      git checkout -b branch_name
# add commits here
git push -u origin HEAD:branch_name
    • Create a merge request in GitLab web interface from branch_name in your fork to your.name in the repo.
Merge the latest changes from main/master branch
git checkout your.name
git fetch main
git merge main/master
# Resolve conflicts
git push
