Liferay Portal is an open source enterprise web platform for building business solutions that deliver immediate results and long-term value. Liferay Portal started out as a personal development project in 2000 and was open sourced in 2001.
To get started, check out the project's community homepage at http://liferay.org!
Liferay Portal releases are built from the liferay-portal repository and include select plugins from the liferay-plugins repository. You can build Liferay Portal, its plugins, and/or any of the other supporting technologies from their respective repositories.
To get up and running quickly, download a pre-built Liferay release and follow the Quick Start instructions. For more detailed installation instructions, please read the Deployment section of documentation on the Liferay Developer Network.
