+The redux form is rendered by importing and using `DispatchRenderer` from `@jsonforms/core`.
 `DispatchRenderer` expects `schema` and `uischema` props which define 
 the form to be rendered but if those are omitted, they will be pulled from the 
 store which was provided via `Provider` previously.
 
-Since we also like to display the actual data that is being edited we 
-`connect` the `App` component to the store in order to extract the data 
-from it. 
+The standalone form is rendered by importing and using the `JsonForms` component and directly
+handing over the `schema`, `uischema`, `data`, `renderer` and `cell` props. We listen to changes
+in the form via the `onChange` callback .
 
 ## Custom renderers
