+# Enabling networking
+- In order to access the public internet, you will need an Exit Node. See [Tailscale Exit Nodes](https://tailscale.com/kb/1103/exit-nodes/) for detailed instructions.
+	- ***Note:*** This is not required to access machines in your own Tailscale Network.
+- depending on your network speed, you may need to wait a few moments for the Tailscale Wasm module to be downloaded.
+
+**When all set:**
+- Log in with your Tailscale credentials.
+- Go back to the WebVM tab. `Connect to Tailscale` should be replaced by your IP address.
+- Start firing network requests!
+
+# Log in to Tailscale with an Auth key
+
+- Add `#authKey=<your-key>` at the end of the URL.
+- Done, you don't need to manually log in anymore.
+
+It is recommended to use an ephemeral key.
+
+# Log in to a self-hosted Tailscale network (Headscale)
+
+- Add `#controlUrl=<your-control-url>` at the end of the URL.
+- You can combine this option with `authKey` with a `&`: `#controlUrl=<url>&authKey=<key>`.
