 ## Basic Usage
 You have one primary way to import this Fetcher, which is the same for all fetchers.
@@ -31,6 +31,7 @@ All methods for making requests here share some arguments, so let's discuss them
 - **proxy**: As the name implies, the proxy for this request is used to route all traffic (HTTP and HTTPS). The format accepted here is `http://username:password@localhost:8030`.
 - **proxy_auth**: HTTP basic auth for proxy, tuple of (username, password).
 - **proxies**: Dict of proxies to use. Format: `{"http": proxy_url, "https": proxy_url}`.
+- **proxy_rotator**: A `ProxyRotator` instance for automatic proxy rotation. Cannot be combined with `proxy` or `proxies`. Import from `scrapling.engines.toolbelt import ProxyRotator`.
 - **headers**: Headers to include in the request. Can override any header generated by the `stealthy_headers` argument
 - **max_redirects**: Maximum number of redirects. **Defaults to 30**, use -1 for unlimited.
 - **verify**: Whether to verify HTTPS certificates. **Defaults to True**.

+You can also use a `ProxyRotator` with `FetcherSession` for automatic proxy rotation across requests:
+
+```python
+from scrapling.fetchers import FetcherSession
+from scrapling.engines.toolbelt import ProxyRotator
+
+rotator = ProxyRotator([
+    'http://proxy1:8080',
+    'http://proxy2:8080',
+    'http://proxy3:8080',
+])
+
+with FetcherSession(proxy_rotator=rotator, impersonate='chrome') as session:
+    # Each request automatically uses the next proxy in rotation
+    page1 = session.get('https://example.com/page1')
+    page2 = session.get('https://example.com/page2')
+
+    # You can check which proxy was used via the response metadata
+    print(page1.meta['proxy'])
+```
+
+You can also override the session proxy (or rotator) for a specific request by passing `proxy=` directly to the request method:
+
+```python
+with FetcherSession(proxy='http://default-proxy:8080') as session:
+    # Uses the session proxy
+    page1 = session.get('https://example.com/page1')
+
+    # Override the proxy for this specific request
+    page2 = session.get('https://example.com/page2', proxy='http://special-proxy:9090')
+```
+
 And here's an async example
 
 ```python
 async with FetcherSession(impersonate='firefox', http3=True) as session:
     # All standard HTTP methods available
-    response = async session.get('https://example.com')
+    response = await session.get('https://example.com')

+    response = await session.put('https://scrapling.requestcatcher.com/put', data={'update': 'info'})
-    response = async session.delete('https://scrapling.requestcatcher.com/delete')
