The Tiki Wiki CMS community looks to provide a high-quality, fully integrated content management system in the true spirit of an open source software project. The community is encouraged to provide integration services for Tiki to organizations and businesses; to develop custom applications; and to provide those customization back into the codebase for community use.
See the Tiki Wiki Model for more information about how the community organizes and functions
