Configuring vscode as Git diff tool

README.md

If you are using Visual Studio Code Insiders (for early adopters) you may need to have a vscode instance/window already running before running your difftool, otherwise it may crash once you finish reviewing the first file (when you have more than one file to check diffs)

git config --global diff.tool vscode
git config --global difftool.vscode.cmd 'code --wait --diff $LOCAL $REMOTE'

to undo the changes, either run:

git config --global --unset diff.tool
git config --global --unset difftool.vscode.cmd

or run git config --global -e and delete the respective lines
