+    """
+    Spawns a new instance of the selected `collection` from the given `scene`. 
+    If the `scene` is empty or null, the current active scene is used. Each spawned 
+    instance has an empty owner object to control the instance as a whole (like Blender
+    uses it for collection instances).
+
+    @input Scene: Scene in which the collection belongs.
+    @input Collection: Collection to be spawned.
+    @input In: activates the node.
+    @input Transform: the transformation of the instance that should be
+        spawned. Please note that the collection's instance offset is
+        also taken into account.
+
+    @output Out: activated when a collection instance was spawned. It is
+        not activated when no collection is selected.
+    @output Top-Level Objects: all objects in the last spawned
+        collection that are direct children of the owner object of the
+        collection's instance.
+    @output All Objects: all objects in the last spawned collection.
+    @output Owner Object: The owning object of the last spawned
+        collection's instance.
