+        # React Hooks
+
+        React Hooks are functions that let you "hook into" React state and lifecycle features from function components.
+
+        ## useState
+
+        The `useState` Hook lets you add React state to function components.
+
+        ```javascript
+        import { useState } from 'react';
+
+        function Example() {
+          const [count, setCount] = useState(0);
+
+          return (
+            <div>
+              <p>You clicked {count} times</p>
+              <button onClick={() => setCount(count + 1)}>
+                Click me
+              </button>
+            </div>
+          );
+        }
+        ```
+
+        ## useEffect
+
+        The `useEffect` Hook lets you perform side effects in function components.
+
+        ```javascript
+        import { useEffect } from 'react';
+
+        function Example() {
+          useEffect(() => {
+            document.title = `You clicked ${count} times`;
+          });
+        }
+        ```
+
+        ## Best Practices
+
+        - Only call Hooks at the top level
+        - Only call Hooks from React functions
+        - Use multiple Hooks to separate concerns
