This is a Balsmiq template allowing you to quickly create mockups for the Umbraco backend.
You will need to have Balsamiq installed on your computer which can be downloaded as a 7 day trial from http://www.balsamiq.com/
It is an excellent way to show ideas for packages and bespoke ares in the Umbraco backend to clients and developers helping make development a more visual experience.
Enjoy...:)
