How to create a plugin based controller in Umbraco? I have followed the guide on https://github.com/Shandem/Umbraco4Docs/blob/4.8.0/Documentation/Reference/Mvc/surface-controllers.md.
But when browsing to ~/umbraco/areaname/controllername I get a 404. The only way not getting this is removing the plugin attribute. But I want to use the plugin architecture. So what else needs to be done besides the instruction mentioned in the guide.
The documentation is really awful if you want to get started with Umbraco and MVC.
By the way I am using Umbraco 6.
