Commit your local changes

git add .
git commit -m ‘Commit msg’
Try to get the changes (will fail)

git pull

Pull is not possible because you have unmerged files.
Please, fix them up in the work tree, and then use 'git add/rm <file>'

Open the conflict file and fix the conflict. Then:

git add .
git commit -m ‘Fix conflicts’
git pull
will report something like:
