First you need to fork the repository into your own account. You can do that simply by clicking the fork button on the gitlab interface.
https://gitlab.inria.fr/solverstack/pastix/forks/new
Then, clone the repository on your laptop:
#!shell
git clone [email protected]:username/forkname.git
Once this is done, you can setup the PaStiX repository as the upstream of your clone to simplify the update of your fork repository.
#!shell
git remote add upstream [email protected]:solverstack/pastix.git
Now, you have your repository configured, and you want to create a new pull request. The first step is to create a branch from the HEAD of the your fork repository.
#!shell
git branch your_branch_name
git checkout your_branch_name
Commit your modifications into your branch. Then, you need to push this new branch to your online repository
#!shell
git push origin your_branch_name
Once your branch is online, on the gitlab interface, go to the branches webpage, select the branch you want to push as a merge request, and push the button !!!
Be careful to check the 'close after merge' check box, and to push to the solverstack/pastix repository By default the checkbox is not checked, but the repository should be the correct one by default.
Follow the instructions describes by the "Check out branch" button associated to the merge request.
