+### Example
+
+Using python and playwright, following snippet leverages the addons capability to serve as a remote web runner. This functionality can be used ad hoc or within an integration of course. The addons requires to be address by its IP, which is why we pre-resolve it in this snipped.
+
+`pip install playwright`
+
+```python
+import asyncio
+import time
+from playwright.async_api import async_playwright
+import socket
+import re
+
+# Set the remote addr
+remote = 'homeassistant.local'    # Use in case of mdns local domain
+# remote = 'homeassistant.home'   # Use in case of private DNS server
+# remote = '192.168.1.36'         # Use in case of direct IP
+# remote = 'localhost'            # Use in case of running directly inside the addon
+
+port = "9222"

+# Regex match for IP address
+ipv4_pattern = re.compile(r'^(\d{1,3}\.){3}\d{1,3}$')
