FLOSS Manuals is a collection of manuals about free and open source software together with the tools used to create them and the community that uses those tools. They include authors, editors, artists, software developers, activists, and many others. There are manuals that explain how to install and use a range of free and open source softwares, about how to do things (like design or stay safe online) with open source software, and manuals about free culture services that use or support free software and formats.
Anyone can contribute to a manual – to fix a spelling mistake, to add a more detailed explanation, to write a new chapter, or to start a whole new manual on a topic.
