//Now that the export from translatewiki.net with https://gerrit.wikimedia.org/r/#/c/mediawiki/core/+/459274/ has happened://
This does not require you to speak that language. This task is about MediaWiki core.
Add the Eastern Pwo language to the list of languages found in `languages/data/Names.php`, and then add a file in `languages/messages/` that gives information on how to treat the language (such as the [fallback language](https://www.mediawiki.org/wiki/Manual:Language#Fallback_languages) and [directionality](https://en.wikipedia.org/wiki/Writing_system#Directionality)).
This is important so that MediaWiki knows what languages are available and how to handle them. The [Wikipedia article on Eastern Pwo](https://en.wikipedia.org/wiki/Eastern_Pwo_language) would be useful.
There is no prerequisite knowledge needed for this task.
You are expected to provide a patch in Wikimedia Gerrit. See https://www.mediawiki.org/wiki/Gerrit/Tutorial for how to set up Git and Gerrit.
