 # KDecoration2
 
 Plugin based library to create window decorations.
 
 ## Introduction
 
 KDecoration2 is a library to create window decorations. These window decorations can be used by
 for example an X11 based window manager which re-parents a Client window to a window decoration
 frame.
 
 The library consists of two parts:
 * Decoration API for implementing a Decoration theme
 * Private API to implement the backend part (e.g. from Window Manager side)
 
 ## Providing a Decoration
 
 To provide a custom decoration one needs to create a plugin and provide an own implementation
 of KDecoration2::Decoration. For a framework to load and find the plugin it needs to be compiled
 with the proper json metadata. An example for such metadata (deco.json):
 
     {
         "KPlugin": {
             "Id": "org.kde.myAweseomeDecoration",
             "ServiceTypes": [
                 "org.kde.kdecoration2"
             ]
         },
         "org.kde.kdecoration2": {
             "blur": false, /* blur behind not needed */
             "kcmodule": true /* comes with a configuration module */
         }
     }
 
 To simplify one can use the KPluginFactory macro from the KCoreAddons framework:
 
     K_PLUGIN_FACTORY_WITH_JSON(
         MyAwesomeDecorationFactory,
         "deco.json",
         registerPlugin<MyAwesomeDecoration::Decoration>();
     )
 
-The plugin needs to get installed to `${PLUGIN_INSTALL_DIR}/org.kde.kdecoration2`.
+The plugin needs to get installed to `${KDE_INSTALL_PLUGINDIR}/org.kde.kdecoration2`.
