-## Auto-tunneling override
+### Auto-tunneling to a specific tunnel by wifi name and/or mobile data

+A common scenario is when a user wants to use a specific tunnel config when they are connected to certain networks.

+and then want to connect to their VPN provider's server while at home.

+%product% now allows users to configure each tunnel to be used on specific Wi-Fi networks and/or mobile data.
+Tunnels configured with these settings will be prioritized over the primary tunnel if the app detects a match.

+To configure:
+- Long press on the tunnel config you would like to configure from the main screen
+- Click the gear icon
+- Add a Wi-Fi name where you would like to prioritize using this tunnel or turn on mobile data if this is your mobile data specific tunnel.

+%product% auto-tunneling will now prioritize using this specific tunnel if it detects a matching network scenario.

+# Getting started
+
+It is important to understand that %product% is a <tooltip term="vpn_client">VPN client</tooltip> application and not a 
+<tooltip term="vpn_service">VPN service</tooltip> provider. In short, this means that this application does not provide
+a VPN server for users to connect to by default. It is expected that the user either is hosting their own VPN server, or
+they are paying a <tooltip term="vpn_service">VPN service</tooltip> provider. 
+
+If you are new to using VPNs and do not yet have a <tooltip term="vpn_service">VPN service</tooltip> provider or VPN server,
+one of the easiest ways to get started is with a free <tooltip term="vpn_service">VPN service</tooltip> provider like <a href="https://protonvpn.com/">ProtonVPN</a>.
+
+<warning>
+    <p>
+        I do not personally use <a href="https://protonvpn.com/">ProtonVPN</a>, nor am I advocating for using their services.
+        The reason I am referencing this company in these docs is because they happen to be a well-known VPN provider with a free tier and an
+        easy method for exporting <a href="https://www.wireguard.com/">WireGuard</a> configurations.
+        It is <format style="bold">highly recommended</format> you do your own research on which VPN provider you want to use as you are trusting them with access to
+        to your sensitive internet traffic data. 
+    </p>
+</warning>
+
+### Steps for getting a WireGuard config: 
+- Create a new account on <a href="https://protonvpn.com/">ProtonVPN</a>'s site.
+- Follow their <a href="https://protonvpn.com/support/wireguard-configurations/">tutorial</a> on how to export a <a href="https://www.wireguard.com/">WireGuard</a> configuration file.
+- On the main screen of %product%, click the floating action button and select "Add from file or zip".
+- Navigate to your newly downloaded <a href="https://www.wireguard.com/">WireGuard</a> configuration file and select it.
+
+You are now ready to start using %product% as your Android VPN client.
