+<div class="note">
+    This documentation was relevant for the Sling Starter and Lauchpad until version 11. Starting with Sling 12 the
+    Sling Starter is assembled and launched using the <a href="/documentation/development/feature-model.html">OSGi Feature Model</a>.
+    It is recommended that new projects use the OSGi Feature Model instead of the Sling Launchpad.

 This tries to explain how exactly the Sling Launchpad works, what constitutes the Sling Launchpad and how you can use the Sling Launchpad to custom create you Sling launchers. For a view behind the scenes of the Sling Launchpad Base module (the actual launcher) you might want to refer to the [Embedding Sling](/documentation/development/embedding-sling.html) page.
