Once the Installation of KitchenDraw is complete, you should read the Tutorial document first. It shows you how to create a simple kitchen, from the drawing of the walls to the final estimate.
From then on, if you come up against any particular difficulty, you will probably find the answer in the How to? document.
Advanced planning functions and KitchenDraw customization are dealt within the Advanced Features document.
Finally, if you wish to produce photorealistic pictures or edit your own catalogs, you will find all the information you need in the Photorealism and Catalog Edition documents.
