+
+# Customizing Reactjs-Tiptap-Editor
+
+There are 3 main ways to customize the Reactjs-Tiptap-Editor:
+
+### 1. Extensions
+
+Add extensions to enhance editor functionality:
+
+```tsx
+import React from 'react'
+import RichTextEditor, { BaseKit, Bold, BulletList, Heading, Italic } from 'reactjs-tiptap-editor'
+import 'reactjs-tiptap-editor/style.css'
+
+const extensions = [BaseKit, Heading, Italic, Bold, BulletList]
+
+export default function App() {
+  return (
+    <RichTextEditor
+      content=""
+      output="html"
+      extensions={extensions}
+    />
+  )
+}
+```
+
+### 2. Editor Options
+
+The `useEditorOptions` property provides configuration options for customizing the editor's behavior with the `UseEditorOptions` interface.
+
+### Interface
+
+```tsx
+interface UseEditorOptions {
+  /** Called when editor content is updated */
+  onUpdate?: (props: { editor: Editor, transaction: Transaction }) => void
+
+  /** Called when editor selection changes */
+  onSelectionUpdate?: (props: { editor: Editor, transaction: Transaction }) => void
+
+  /** Called when editor gains focus */
+  onFocus?: (props: { editor: Editor, event: FocusEvent }) => void
+
+  /** Called when editor loses focus */
+  onBlur?: (props: { editor: Editor, event: FocusEvent }) => void
+
+  /** Called when editor transaction is created */
+  onTransaction?: (props: { editor: Editor, transaction: Transaction }) => void
+
+  /** Called when editor is created */
+  onCreate?: (props: { editor: Editor }) => void
+
+  /** Called before editor is destroyed */
+  onDestroy?: () => void
+
+  /** Initial editor state */
+  editorState?: string
+
+  /** Enable or disable parsing content */
+  enableInputRules?: boolean
+  enablePasteRules?: boolean
+
+  /** Enable or disable content editing */
+  editable?: boolean
+
+  /** Custom autofocus behavior */
+  autofocus?: boolean | 'start' | 'end' | number
+
+  /** Editor view props */
+  editorProps?: EditorProps
+}
+```
+
+Example with editor options:
+
+```tsx
+import React from 'react'
+import RichTextEditor, { BaseKit, type UseEditorOptions } from 'reactjs-tiptap-editor'
+import 'reactjs-tiptap-editor/style.css'
+
+const extensions = [BaseKit]
+
+const customOptions: UseEditorOptions = {
+  onUpdate: ({ editor }) => console.log('Content updated:', editor.getText()),
+  onSelectionUpdate: ({ editor }) => console.log('Selection updated:', editor.getText()),
+  onFocus: () => console.log('Editor focused'),
+  onBlur: () => console.log('Editor blurred'),
+  editable: true,
+  autofocus: 'start',
+}
+
+export default function App() {
+  return (
+    <RichTextEditor
+      content=""
+      output="html"
+      useEditorOptions={customOptions}
+      extensions={extensions}
+    />
+  )
+}
+```
+
+### 3. Accessing the Editor Instance
+
+There are two ways to access the editor instance:
+Direct access to the editor instance using `useRef` or `useEditorState`
+
+#### Using useRef:
+
+```tsx
+import React, { useRef } from 'react'
+import RichTextEditor, { BaseKit, type Editor } from 'reactjs-tiptap-editor'
+import 'reactjs-tiptap-editor/style.css'
+
+const extensions = [BaseKit]
+
+export default function App() {
+  const editorRef = useRef<{ editor: Editor | null }>(null)
+
+  const handleCustomButton = () => {
+    if (editorRef.current?.editor) {
+      const text = editorRef.current.editor.getText()
+      console.log('Current selected text:', text)
+    }
+  }
+
+  return (
+    <div>
+      <RichTextEditor
+        content=""
+        output="html"
+        ref={editorRef}
+        extensions={extensions}
+      />
+      <button type="button" onClick={handleCustomButton}>
+        Custom Action
+      </button>
+    </div>
+  )
+}
+```
+
+#### Using useEditorState:
+
+```tsx
+import RichTextEditor, { BaseKit, useEditorState } from 'reactjs-tiptap-editor'
+import 'reactjs-tiptap-editor/style.css'
+
+const extensions = [BaseKit]
+
+export default function App() {
+  const { isReady, editor, editorRef } = useEditorState()
+
+  const handleCustomButton = () => {
+    if (editor) {
+      const text = editor.getText()
+      console.log('Current text:', text)
+    }
+  }
+
+  return (
+    <div>
+      <RichTextEditor
+        content=""
+        output="html"
+        ref={editorRef}
+        extensions={extensions}
+      />
+      {isReady && (
+        <button type="button" onClick={handleCustomButton}>
+          Custom Action
+        </button>
+      )}
+    </div>
+  )
+}
+```
+
+### Example: Custom Bubble Menu with Selection Text
+
+```tsx
+import RichTextEditor, { BaseKit, BubbleMenu, useEditorState } from 'reactjs-tiptap-editor'
+import type { Editor } from 'reactjs-tiptap-editor'
+import 'reactjs-tiptap-editor/style.css'
+
+interface CustomBubbleMenuProps {
+  editor: Editor
+}
+
+function CustomBubbleMenu({ editor }: CustomBubbleMenuProps) {
+  if (!editor)
+    return null
+
+  const handlePrintSelection = () => {
+    const { from, to } = editor.state.selection
+    const text = editor.state.doc.textBetween(from, to)
+    console.log('Selected text:', text)
+  }
+
+  return (
+    <BubbleMenu
+      editor={editor}
+    >
+      <button
+        type="button"
+        onClick={handlePrintSelection}
+      >
+        Print Selection
+      </button>
+    </BubbleMenu>
+  )
+}
+
+const extensions = [BaseKit]
+
+export default function App() {
+  const { isReady, editor, editorRef } = useEditorState()
+
+  return (
+    <div>
+      <RichTextEditor
+        ref={editorRef}
+        content=""
+        output="html"
+        extensions={extensions}
+        hideBubble
+      />
+      {isReady && editor && <CustomBubbleMenu editor={editor} />}
+    </div>
+  )
+}
+```
