If you are reading this page, the Docs Team hopes you will take the next steps to maintaining, improving and contributing to the Joomla! Project's Documentation. Our documentation is written by users, developers, and code contributors for the benefit of the same. There are many Open Source Projects using Mediawiki software succesfully for their project's documentation. The Mediawiki software allows for open collaboration, version control of pages, tracking changes similar to Git and a large base of extensions to extend the user interface. A wiki is hard to break with its excellent page history. Make a mistake and just undo or revert the page back to the previous version.
If you are new to the use of Wikis and the simple markup to create pages, then you can use the following for help.
Once you have a wiki account, you are free to work on any aspect of the documentation that takes your fancy. Don't worry, sometimes even the most seasoned wiki editors can get lost, distracted or confused about what to do next. Even the simplest contributions such as spelling corrections and grammar fixes are a tremendous help!
If you want to start a new page, please do some research first and try not to create a new article if one already exists. Use the search feature of the Docs Wiki to see if your topic is already in an article. Duplication will be merged and/or deleted. Don't be afraid to modify, reformat or improve someone else's work on the Joomla! Docs Wiki! This is a collaborative documentation wiki, just make sure you are following the policy and style guide.
Here are just a few suggestions below that really need some love and attention.
Help pages, yes we know they are a lot of work, but necessary for beginners and even those with intermediate knowledge of Joomla! The Joomla! 2.5 Help Screens are complete but Joomla! 3.x are still being worked on! The contributions you give to them will be appreciated by many users worldwide. You can find the matrix of 3.x Help Screens here. Some just need to be reviewed and marked complete in status, others need to be started, completed, have images uploaded(670px max width), etc.
Here a a few things to remember as a Joomla! Docs contributor.
