+# Textarea
+
+사용자가 텍스트를 입력하는 필드로, 여러 줄의 텍스트 입력이 필요한 경우 사용됩니다. 다양한 상태와 속성을 지원하여 사용자 경험을 향상시킬 수 있습니다.
+
+<Canvas of={TextareaStories.Default} />
+<Controls />
+
+<br />
+<br />
+
+## 사용법
+
+Textarea의 기본 사용법입니다.
+
+필수 프로퍼티인 `width`와 `height`를 사용하여 Textarea의 크기를 설정해주세요.
+
+```tsx
+import { Textarea } from '@yourssu/design-system-react';
+```
+
+```tsx
+<Textarea width="343px" height="187px" />
+```
+
+이외의 프로퍼티들은 하단의 예시에서 확인할 수 있습니다.
+
+<br />
+<br />
+
+## 예시
+
+### placeholder
+
+Textarea에 표시되는 짧은 안내 문구로, 사용자가 입력해야 할 내용의 예시를 보여줍니다.
+
+```tsx
+<Textarea width="343px" height="187px" placeholder="Enter text here..." />
+```
+
+<Canvas of={TextareaStories.Placeholder} withSource="none" />
+
+<br />
+<br />
+
+### helperText
+
+Textarea에 사용자가 올바르게 입력할 수 있도록 돕는 텍스트입니다.
+
+```tsx
+<Textarea
+  width="343px"
+  height="187px"
+  helperText="helperText입니다."
+  placeholder="Enter text here..."
+/>
+```
+
+<Canvas of={TextareaStories.HelperText} withSource="none" />
+
+<br />
+<br />
+
+### maxLength
+
+Textarea에 사용자가 입력할 수 있는 최대 글자 수를 제한합니다.
+
+```tsx
+<Textarea width="343px" height="187px" maxLength={50} placeholder="Max 50 characters" />
+```
+
+<Canvas of={TextareaStories.MaxLength} withSource="none" />
+
+<br />
+<br />
+
+### disabled
+
+Textarea에 어떠한 입력을 할 수 없도록 막습니다.
+
+```tsx
+<Textarea
+  width="343px"
+  height="187px"
+  disabled={true}
+  helperText="Text Inputting"
+  placeholder="This field is disabled"
+/>
+```
+
+<Canvas of={TextareaStories.Disabled} withSource="none" />
+
+<br />
+<br />
+
+### error
+
+Textarea에 잘못된 값이 입력되었을 때 사용자에게 오류 상태를 표시하는 데 사용됩니다.
+
+```tsx
+<Textarea
+  width="343px"
+  height="187px"
+  error={true}
+  helperText="Text Inputting"
+  placeholder="There is an error"
+/>
+```
+
+<Canvas of={TextareaStories.Error} withSource="none" />
+
+<br />
+<br />
+
+### onValueChange
+
+Textarea에 텍스트를 입력하거나 변경할 때 호출되는 콜백 함수입니다. 이 함수는 현재 입력된 텍스트 값을 매개변수로 전달하여, 외부에서 상태를 관리하거나 추가적인 로직을 실행할 수 있게 합니다.
+
+```tsx
+const [text, setText] = useState('');
+
+const handleValueChange = (newValue: string) => {
+  setText(newValue);
+};
+
+return (
+  <Textarea
+    {...args}
+    value={text}
+    onValueChange={handleValueChange}
+    maxLength={args.maxLength}
+    placeholder={args.placeholder}
+  />
+);
+```
+
+<Canvas of={TextareaStories.OnValueChange} withSource="none" />
+
+<br />
+<br />
