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.
 * 4) Escoge un proyecto de software
 * 5) Escoge y resuelve una tarea (escribe y prueba tu código)
 * 1) Envía tus cambios de código

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

Basics of how Wikimedia software projects work
Wikimedia tiene cientos de proyectos de software en muchas áreas diferentes. si quieres obtener una visión general.

Quienes mantienen a cada proyecto de software son bastante libres de elegir la infraestructura que prefieran. En general, básicamente todos los proyectos de software tienen


 * Un task tracking herramienta en la que se notifican, gestionan y debaten los fallos de los programas informáticos y las solicitudes de mejora.Ejemplos son Wikimedia Phabricator, GitHub, o Sourceforge.
 * a code repository where the source code can be "checked out" to everybody. Examples are Wikimedia Git/Gerrit, GitHub, or Sourceforge.
 * a code review tool where proposed code changes (so-called patches) get discussed and improved. Examples are Wikimedia Git/Gerrit, GitHub, or Sourceforge. Once your proposed patch is good and is merged into the code repository, your code changes will become available to everybody. (You could read more about good practices for code review here.)
 * general places for discussion of the software project and/or for receiving help and support. Those places can be mailing lists or IRC chat channels or wiki pages or other places. The exact places depend on each project. You could also contact specific mentors via "Email this user" on their user pages, but note that "questions asked in private don't help others".

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".
