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 Installation and Setup chapter of the Liferay User Guide.
If you wish to build core Liferay or its plugins, read the CONTRIBUTING guide. It includes details on using the repositories and building the software.
For transparency and insight into Liferay's release cycle, and for striving to maintain backward compatibility, we make a strong effort to uphold the Versioning Guidelines for our software.
