 ### Vision
+* function `getPropertyValue(name: Name, inherit: Boolean = false, includeStyles: Boolean = true, includeDefaults: Boolean = true)` - get property value with given layer flags.
 
-* function `getProperty(name: Name, inherit: Boolean, includeStyles: Boolean, includeDefaults: Boolean)`. 
+* function `setProperty(name: Name, item: Any?)` - a convenient method to set property node or value. If `item` is null, then node is removed, not a value
+Sets the `item` property to the element with the `name` identification. 
 
-It gets properties of element with `name` identification.
-`inherit` — toggles parent node property lookup. Null means inference from descriptor. Default is false.
-`includeStyles` — toggles inclusion of. Null means inference from descriptor. Default is true. 
-`includeDefaults` — default is false.
+### SolidGroup
 
-* function `setProperty(name: Name, item: MetaItem?, notify: Boolean = true)`
+* function `getPrototype(name: Name)` - get a prototype redirecting the request to the parent if prototype is not found. If prototype is a ref, then it is unfolded automatically.
 
-Sets the `item` property to the element with the `name` identification. `notify` is a value which toggles the necessity of the change notification. Default is true.
+* function `prototypes(builder: VisionContainerBuilder<Solid>.() -> Unit)` - create or edit prototype node as a group. 
+
+### RootVisionGroup
+
+Non-serializable root group used to propagate manager to its children.
+
+* function Vision.root(manager: VisionManager) - designate this [VisionGroup] as a root group and assign a [VisionManager] as its parent.
