 ### Automatic type generation
 
 Lexical does not generate the accurate type definitions for your richText fields for you yet - this will be improved in the future. Currently, it only outputs the rough shape of the editor JSON which you can enhance using type assertions.

+## Admin customization
+
+The Rich Text Field editor configuration has an `admin` property with the following options:
+
+| Property                       | Description                                                                                                                            |

+
+### Disable the gutter
+
+You can disable the gutter (the vertical line padding between the editor and the left edge of the screen) by setting the `hideGutter` prop to `true`:
+
+```ts
+{
+  name: 'richText',
+  type: 'richText',
+  editor: lexicalEditor({
+    admin: {
+      hideGutter: true
+    },
+  }),
+}
+```
+
+### Customize the placeholder
+
+You can customize the placeholder (the text that appears in the editor when it's empty) by setting the `placeholder` prop:
+
+```ts
+{
+  name: 'richText',
+  type: 'richText',
+  editor: lexicalEditor({
+    admin: {
+      placeholder: 'Type your content here...'
+    },
+  }),
+}
