+			<p>The plugin API is based off of the ServiceLoader class <i>(Service Provider Interface pattern)</i>. With this in mind to have Recaf load your extensions you will need to declare your plugin classes in the file <span class="code">src/META-INF/services/me.coley.plugin.Plugin</span>. If you do not update this file, your plugin will not be loaded. The existing code in the <a href="https://github.com/Col-E/Recaf-plugin-workspace">workspace example</a> includes this file, but when you rename your plugin name or package do remember to update the service file.</p>
