  1. Resolve conflicts in a file manually: Look for markers <<<<<<<, ======= and >>>>>> in the file and make the edits. When done, run the following command…

  2. Use the version from the source branch and overwrite your changes…
    git checkout --theirs file_with_conflicts
    git add file_with_conflicts
  3. Use your version and reject the changes in the source branch…
    git checkout --ours file_with_conflicts
    git add file_with_conflicts
