Two alternatives are explained: using the command line, and directly editing the config file.

Setting up from the command line

Being the installation path "C:Program Files\Perforce\p4merge.exe", just run:

$ git config --global diff.tool p4merge

# io.js on raspberry pi

installing io.js is now really easy thanks to the io.js and nvm team.
They provides prebuilt binaries for arm.

## get the system up to date
io.js require packages that are not available on the standard (Wheezy) need to change to Jessie.
Update your package url
