+You can configure the RichText appearance and behavior with the following properties:
 
-- Show/hide **menubar** using the [`menubar`](api/config/menubar.md) property
-- Configure **toolbar** using the [`toolbar`](api/config/toolbar.md) property
-- Enable the **fullscreen mode** using the [`fullscreenMode`](api/config/fullscreen-mode.md) property
-- Toggle the **layout** between "classic" and "document" modes using the [`layoutMode`](api/config/layout-mode.md) property
-- Specify **initial value** using the [`value`](api/config/value.md) property
-- Specify **initial locale** using the [`locale`](api/config/locale.md) property
-- Apply **initial styles** using the [`defaultStyles`](api/config/default-styles.md) property

 ## Layout modes
 
-There are two layout modes of RichText editor between which you can select to get the best working place for creating your perfect content:
+RichText supports two layout modes for the editing area:
 
-- **"classic"**

 <div className="img_border">
 ![Document mode](./../assets/richtext/document_mode.png)
 </div>
 
-To specify the desired mode, you need to define it in the [`layoutMode`](api/config/layout-mode.md) property of the RichText configuration object during initialization of the component:

+## Initialize RichText
 
 Initialize RichText with the `richtext.Richtext` constructor. The constructor takes two parameters:
 
-- an HTML container (the ID of the HTML container)
-- an object with configuration properties. [See the full list here](#configuration-properties)
+- a container — a CSS selector or a DOM element
+- a configuration object with the editor properties. See the [full list of properties](#configuration-properties) below
+
+The example below initializes RichText in the `#root` container:
 
 ~~~jsx title="index.html"
-// create RichText
 const editor = new richtext.Richtext("#root", {
     // configuration properties  
 });
 ~~~
 
 ### Configuration properties
 
+Add configuration options as keys of the configuration object.
+
 :::note
-The full list of properties to configure **RichText** can be found [**here**](api/overview/properties_overview.md).
+For the full list of configuration properties, see the [Properties overview](api/overview/properties_overview.md).
 :::
 
+## Destroy the RichText instance
+
+Call the [`destructor()`](api/methods/destructor.md) method to remove the RichText HTML and detach all related events:
+
+~~~jsx
+const editor = new richtext.Richtext("#root", {
+    // configuration properties
+});
