##git mergetool
In the middle file (future merged file), you can navigate between conflicts with ]c and [c.
Choose which version you want to keep with :diffget //2 or :diffget //3 (the //2 and //3 are unique identifiers for the target/master copy and the merge/branch copy file names).
:diffupdate (to remove leftover spacing issues)
:only (once you’re done reviewing all conflicts, this shows only the middle/merged file)
Each of these commands will run an ad hoc http static server in your current (or specified) directory, available at http://localhost:8000. Use this power wisely.
$ python -m SimpleHTTPServer 8000
