your user to be able to configure your extension, you'll need to provide one or more configuration variables. It is a good idea to give those variables a unique name. They should also follow MediaWiki <a href="https://www-mediawiki-org.translate.goog/wiki/Special:MyLanguage/Manual:Coding_conventions/PHP?_x_tr_sl=auto&_x_tr_tl=te&_x_tr_hl=te#Naming" title="Special:MyLanguage/Manual:Coding conventions/PHP">naming conventions</a> (e.g. global variables should begin with $wg).</p> <p>For example, if your extension is named "MyExtension", you might want to name all your configuration variables to begin with <code>$wgMyExtension</code>. It is important that <b>none</b> of the MediaWiki core begins its variables this way and you have done a reasonable job of checking to see that none of the published extensions begin their variables this way. Users won't take kindly to having to choose between your extension and some other extensions because you chose overlapping variable names.</p> <p>It is also a good idea to include extensive documentation of any configuration variables in your installation notes.</p> <p>Here is an example boiler plate that can be used to get started:</p> <div class="mw-highlight mw-highlight-lang-json

This results in a maintenance burden (backwards-compatibility hacks need to be kept around for a long time, and changes to the extension need to be tested with several versions of MediaWiki), but sites running old MediaWiki versions benefit from functionality recently added to the extension.</li> <li>Release branches: release branches of the extension are compatible with matching branches of core, e.g. sites using MediaWiki 1.42 need to use the REL1_42 branch of the extension. (For extensions hosted on <a href="https://www-mediawiki-org.translate.goog/wiki/Special:MyLanguage/gerrit?_x_tr_sl=auto&_x_tr_tl=te&_x_tr_hl=te" title="Special:MyLanguage/gerrit">Gerrit</a>, these branches are automatically created when new versions of MediaWiki are released.)
