Good first bugs



This page provides a list of little bugs and tiny missing features which annoy users and which are relatively easy for a new MediaWiki coder to fix.

These are one way to start getting familiar with the MediaWiki code base. Note that these tasks to not have assigned mentors so you will be more "on your own". If you prefer to work on software projects with mentors, check out the list of software projects that we recommend.

You must have read the "Get started" section of How to become a MediaWiki hacker already to understand the infrastructure, workflows and communication expectations.

Potential bugs to work on
The following sections describe a few example areas in which you can contribute, but you are not limited to these areas!

In the upper right corner of a task (bug report) in Phabricator you can see the product and component that the problem is located in.

This provides you a hint about the Git repository that the code is located in, and about the development team which you could contact if you want to discuss it in a "broader" way (as comments in bug reports should preferably refer to the specific problem described in the report only).

System messages and localization/translation problems
System messages in MediaWiki or its extensions often need small corrections to the English text, but the source text can only be changed in the code by developers, contrary to translations.

This has grown into a large backlog of usually very easy fixes (which might be as easy as fixing a typo).

Also, many messages are unclear and require better documentation (see Localisation).

Missing documentation can also be added by just editing the  subpage of the message on translatewiki.net, like all translations, but may require some study of the code to understand what a message is for: it's therefore optimal to start understanding the code, and very useful for the translators (who do not have such skills).
