   A list/hash of attributes that are exposed to accept data from the parent component. It has an Array-based simple syntax and an alternative Object-based syntax that allows advanced configurations such as type checking, custom validation and default values.
 
+  With Object-based syntax, you can use following options:
+    - **type:** can be one of the following native constructors: `String`, `Number`, `Boolean`, `Array`, `Object`, `Date`, `Function`, `Symbol`, any custom constructor function or an array of those. Will check if a prop has a given type, and will throw a warning if it doesn't. [More information](../guide/components-props.html#Prop-Types) on prop types.
+    - **default:** `any`
+    Specifies a default value for the prop. If the prop is not passed, this value will be used instead. Object or array defaults must be returned from a factory function.
+    - **required:** `Boolean`
+    Defines if the prop is required. In a non-production environment, a console warning will be thrown if this value is truthy and the prop is not passed.
+    - **validator:** `Function`
+    Custom validator function that takes the prop value as the sole argument. In a non-production environment, a console warning will be thrown if this function returns a falsy value (i.e. the validation fails). You can read more about prop validation [here](../guide/components-props.html#Prop-Validation).
