Because the Discovery Framework is built upon the Liferay Portal, you can access Liferay's documentation for more information about how to perform administrative and developer tasks.
Specifically, the Liferay Portal Administrator's Guide provides extensive information about installing, configuring, and maintaining a portal. To access a free PDF download of this guide, go to http://www.liferay.com and navigate to Documentation.
The Discovery Framework Extension Guide (this guide) only covers Endeca extensions to the Liferay Portal. For additional developer support, Liferay provides blogs, wikis, and forums. To access this, go to http://www.liferay.com and navigate to Community.
You can obtain more information about the Discovery Framework and other Endeca products at the Endeca Developer Network (EDeN) at http://eden.endeca.com.
The Discovery Framework documentation set, including the Discovery Framework Installation Guide, Discovery Framework Migration Guide, and Discovery Framework Component Catalog, can be accessed from the EDeN knowledge base.
