Indeed, what now?

You can do two things:

 a) decide not to merge at all:

	git reset --hard

    and you're done. This is what you want to do when you just pulled the 
    wrong branch, for example.

IF you pulled the right branch, and you knew you had other changes through 
other pulls or because you just had done your own development, you want to 
look at:

 b) Try to resolve the merge. Do a "git diff" and look what was unresolved 
    (by looking for those bog-standard resolve conflict markers like 
    "<<<<< old ===== new >>>>>".

    Edit the conflicts by hand to what you want them to be, and do

	git commit --all

    to commit your manual merge.

Note that if you start doing (b) and you decide it's too much for you, you 
can always go back to (a) in the end and ask for help from the people 
involved.
