 Camoufox does **not** fully support injecting Chromium fingerprints. Some WAFs (such as [Interstitial](https://nopecha.com/demo/cloudflare)) test for Spidermonkey engine behavior, which is impossible to spoof.
 
+## Playwright Usage
+
+Camoufox is fully compatible with your existing Playwright code. You only have to change your browser initialization:
+
+```py
+browser = pw.firefox.launch(
+  executable_path='/path/to/camoufox/launch',  # Path to the Camoufox launcher
+  args=['--config', '/path/to/config.json'],  # Pass in file path or JSON string
+)
+```
