Most of Wikimedia's technical spaces use a developer account to identify and authorize users. This account provides access to a number of resources for making technical contributions:
Commit code to Wikimedia's Git repositories via our code review system, powered by Gerrit. See also Gerrit/Tutorial.
Use Wikimedia Cloud Services products that provide cloud computing resources and data services to Wikimedia volunteers. Join Toolforge to run bots and web services or join a Cloud VPS project to test your Wikimedia projects.
Contribute operational documentation on Wikitech, our technical documentation wiki.
