+# ErrorWrapper
+
+The `ErrorWrapper` component is used to gracefully handle and display local errors in UI sections.  
+When the `isError` flag is set to `true`, it shows an error message and an optional retry button.  
+When `isError` is `false`, it renders its children content.
+
+## Installation / Import
+
+```tsx
+import ErrorWrapper from './ErrorWrapper';
+```
+
+## When to Use
+
+- Show a clear error state for a specific part of the interface (e.g., failed data load).
+
+- Wrap a component to display either content or an error depending on state.
+
+- Provide an inline retry mechanism.
+
+## Props
+
+| Name         | Type              | Required | Default | Description                                |
+| ------------ | ----------------- | -------- | ------- | ------------------------------------------ |
+| `text`       | `string`          | ✅       | —       | Error message text.                        |
+| `buttonText` | `string`          | ✅       | —       | Text for the retry button.                 |
+| `handler`    | `() => void`      | ✅       | —       | Callback triggered on retry button click.  |
+| `isError`    | `boolean`         | ✅       | —       | Show error (`true`) or children (`false`). |
+| `children`   | `React.ReactNode` | ✅       | —       | Content rendered when no error occurs.     |
+| `className`  | `string`          | ❌       | —       | Optional CSS class for additional styling. |
+
+## Example
+
+```tsx
+import React from 'react';
+import ErrorWrapper from './ErrorWrapper';
+
+function DataPanel() {
+  const [isError, setIsError] = React.useState(true);
+
+  const handleRetry = () => {
+    console.log('Retry clicked');
+    setIsError(false);
+  };
+
+  return (
+    <ErrorWrapper
+      text="Something went wrong"
+      buttonText="Try again"
+      isError={isError}
+      handler={handleRetry}
+    >
+      <div>Data loaded successfully!</div>
+    </ErrorWrapper>
+  );
+}
+```
