Joomla is an award-winning content management system (CMS), which enables you to build Web sites and powerful online applications. Many aspects, including its ease-of-use and extensibility, have made Joomla the most popular Web site software available. Best of all, Joomla is an open source solution that is freely available to everyone. As of February 2014, Joomla has been downloaded over 50 million times. Over 7,700 free and commercial extensions are available from the official Joomla! Extension Directory, and more are available from other sources.

Flossmanuals

The FLOSS Manuals (FM) is a non-profit foundation founded in 2006 and based in the Netherlands. The foundation is focused on the creation of quality documentation about how to use free software. Its web site is a wiki (previously using the TWiki software, now developed as an autonomous platform with Booki) focused on the collaborative authoring of manuals. The documentation is licensed under the GPL. Although initially the manuals were covered by the GFDL, the license was changed due to concerns about the limited and non-free nature of the GFDL
