After a merge sometimes you have conflicts. You can resolve them by using a merge tool. You can run git mergetool --tool-help to get more details about what tools are supported.

You will get an output like the following
git mergetool --tool=<tool> may be set to one of the following:

      p4merge
        tortoisemerge
        vimdiff
        vimdiff2
        vimdiff3

The following tools are valid, but not currently available:

        araxis
        bc
        bc3
        codecompare
        deltawalker
        diffmerge
        diffuse
        ecmerge
        emerge
