Check out the introduction post about the chrome extension.
git clone git@github.com:mpociot/laravel-testtools.git
# in case you don't have Grunt yet:
sudo npm install -g grunt-cli
cd laravel-testtools
npm install
grunt
When the grunt command is finished, you can use the build/unpacked-dev/ folder to use as the developer version of the extension.
