+### Scenes and Scripts
+
+A `scene` can be created using the [.scene](https://openhab.github.io/openhab-jruby/main/OpenHAB/DSL.html#scene-class_method) method.
+
+```ruby
+scene "Movie", id: "movie", description: "Set up the theatre for movie watching" do
+  Theatre_Window_Blinds.down
+  Theatre_Screen_Curtain.up
+  Theatre_Mood_Light.on
+  Theatre_Light.off
+  Theatre_Projector.on
+  Theatre_Receiver.on
+end
+```
+
+To create a `script`, use the [.script](https://openhab.github.io/openhab-jruby/main/OpenHAB/DSL.html#script-class_method) method.
+Note that scripts can be executed with additional contexts.
+
 ### Hooks
 
 File based scripts can also register [hooks](https://openhab.github.io/openhab-jruby/main/OpenHAB/Core/ScriptHandling.html) that will be called when the script has completed loading (`script_loaded`) and when it gets unloaded (`script_unloaded`).
