Manual:Extension registration

Extension registration refers to the new system of loading extensions that was introduced in MediaWiki 1.25 following a RfC.

Rather than include metadata about extensions inside PHP files that depends upon filescope, global state and load order, these are now stored in an  or   file.

Usage

 * wfLoadExtensions
 * wfLoadSkins

Migrating
A script has been written to help with migrating from PHP entry points to JSON:. If your extension supports older versions of MediaWiki, you should keep your PHP entry point until you drop support for those older versions.
