Wikimedia uses Gerrit as its code review system. That's where you propose code changes and others will review them before your code changes will get merged and become available to everybody.

Many Wikimedia tasks want you to submit your work to Gerrit. Gerrit has a test repository called sandbox. In this task, you should upload a patch against that repository.

Please read through Gerrit tutorial. With the help of this tutorial, upload a patch to sandbox repository. This commit should add new file "yourusername.txt" (please use the same nickname as on the GCI site), which can contain any text you want. The file should be located in /gci folder.

You also want to read https://www.mediawiki.org/wiki/Gerrit/Commit_message_guidelines, which guides you how to write good commit messages.
