How to start contributing
The following steps are a general outline of how to get started contributing:

Follow the Guide to getting your code reviewed and submit a patch.
 * 1) Learn the basics of how Wikimedia open source software projects work.
 * 2) Read the Communication guidelines.
 * 3) Set up accounts: Create a developer account. Depending on the type of contribution you want to make, you may also need to set up accounts in Phabricator, and set up Git and Gerrit.
 * 1) Choose a software project.
 * 1) Choose and solve a task (write and test your code).
 * 1) Submit your code changes for review.

The rest of this guide provides additional details about the process.

Basics of how Wikimedia software projects work
Wikimedia has software projects in.

The maintainers of each software project choose the infrastructure they prefer. In general, most software projects have:


 * a task tracking tool where software bugs and enhancement requests are reported, managed and discussed. Examples are Wikimedia Phabricator, GitHub, or Wikimedia GitLab.
 * a code repository where the source code can be "checked out" to everybody. Examples are Wikimedia Gerrit, GitHub, or Wikimedia GitLab.
 * a code review tool where proposed code changes ("patches") get discussed and improved. Examples are Wikimedia Git/Gerrit, GitHub, or GitLab. After your proposed patch is approved and merged into the code repository, your code changes become available to everybody.
 * general places for discussion of the software project and for help and support. Those places can be mailing lists, IRC chat channels, wiki pages, or other places. The exact places depend on each project.

At any point, if you run into problems or need help, please ask. To ask good questions in the right places, follow the "communication tips".
