+    # Prime Tunnel SDK
+    Expose local services via secure tunnels on Prime infrastructure.
+    ## Installation
+    ```bash
+    uv pip install prime-tunnel

+    Or with pip:
+    ```bash
+    pip install prime-tunnel
+    ```
+    ## Quick Start
+    ```python
+    from prime_tunnel import Tunnel
+    # Create and start a tunnel
+    async with Tunnel(local_port=8765) as tunnel:
+        print(f"Tunnel URL: {tunnel.url}")
+        # Your local service on port 8765 is now accessible at tunnel.url
+    ```
+    ## CLI Usage
+    ```bash
+    # Start a tunnel
+    prime tunnel start --port 8765
+    # List active tunnels
+    prime tunnel list
+    # Get tunnel status
+    prime tunnel status <tunnel_id>
+    ```
