Zen Foundation comes with three built-in brands (breeze, ginseng, and juice), as well as our recommended starting point: Chameleon. You can choose one to get started building your site. Or, you might want to check out our newest Zen addition, the first of our Lightning Series of one-click demo sites: Zen Intranet.
Eventually, most organizations want to customize their site to match their corporate identity. Zen makes that easy with Zen's Brand Designer, which gives amazing control and flexibility over the design of your Zen site.
