Gerrit is the most important part of the development process. All the contributions to MediaWiki are reviewed and approved at To help you get started, check the Tutorial or its short version.

The best way to get started with Quality Assurance is browser testing because it does not require technical experience. If you have technical experience with Ruby and Cucumber you can write and run your own tests.

You can also go for manual testing. Testing new features is done through manual exploratory testing of software built with continuous integration.

API[edit | edit source]

Use this tutorial to help you get started with API.
