How to contribute
Get involved
Do you love software freedom and open source communities? Do you like the MediaWiki software, Wikipedia, or any other Wikimedia sites?
Then, contribute your skills here and learn from other contributors. This page will help you get started by providing an overview of areas where you can get involved.
The content of all Wikimedia projects is released under free licenses. Write code to access, remix and grow this immense pool of free knowledge. Follow the tutorial to get started with the API, available on all MediaWiki wikis, and other APIs for content and Wikidata. Other open data sources, including XML and SQL dumps, are also available.
Our code is all free and open source. Choose a project, provide a patch, and fix a task!
Wikimedia projects use a variety of languages such as PHP and JavaScript in MediaWiki and its extensions, Lua (in Templates), CSS/LESS (in skins etc.), Objective-C, Swing and Java (in Mobile Apps and Kiwix), Python (in Pywikibot), C++ (in Huggle), or C# (in AWB). Create bots to process content and host your tools on Toolforge. Hack on mobile apps or on desktop applications. Or help Site Reliability Engineering maintain the server configuration.

As a Tech ambassador, help other Wikimedians with technical issues, relay Tech News to inform users about what is going to impact them, and join the ambassadors' group and the mailing list to act as a bridge between developers and your local wiki.
English writers can improve the MediaWiki documentation, other essential support pages and, in fact, any page of this website.
If you are fluent in a language other than English you can join the effort by translating this website and the MediaWiki software.
