+### Option: `accept_dns`
+
+If you are experiencing trouble with MagicDNS on this device and wish to
+disable, you can do so using this option.
+
+When not set, this option is enabled by default.
+
+MagicDNS may cause issues if you run things like Pi-hole or AdGuard Home
+on the same machine as this add-on. In such cases disabling `accept_dns`
+will help. You can still leverage MagicDNS on other devices on your network,
+by adding `100.100.100.100` as a DNS server in your Pi-hole or AdGuard Home.
+
+### Option: `accept_routes`
+
+This option allows you to accept subnet routes advertised by other nodes in
+your tailnet.
+
+More information: <https://tailscale.com/kb/1019/subnets/>
+
+When not set, this option is enabled by default.
+
+### Option: `advertise_exit_node`
+
+This option allows you to advertise this Tailscale instance as an exit node.
+
+By setting a device on your network as an exit node, you can use it to
+route all your public internet traffic as needed, like a consumer VPN.
+
+More information: <https://tailscale.com/kb/1103/exit-nodes/>
+
+When not set, this option is enabled by default.
+
+### Option: `advertise_routes`
+
+This option allows you to advertise routes to subnets (accessible on the network
+your device is connected to) to other clients on your tailnet.
+
+By adding to the list the IP addresses and masks of the subnet routes, you can
+use it to make your devices on these subnets accessible within your tailnet.
+
+If you want to disable this option, specify an empty list in the configuration
+(`[]` in YAML).
+
+More information: [Subnet routers][tailscale_info_subnets]
+
+When not set, the add-on by default will advertise routes to your subnets on all
+supported interfaces.
+
+### Option: `funnel`
+
+This requires Tailscale Proxy to be enabled.
+
+**Important:** See also the "Option: `proxy`" section of this documentation for the
+necessary configuration changes in Home Assistant!
+
+When not set, this option is enabled by default.
+
+With the Tailscale Funnel feature, you can access your Home Assistant instance
+from the wider internet using your Tailscale domain (like
+`https://homeassistant.tail1234.ts.net`) even from devices **without installed
+Tailscale VPN client** (for example, on general phones, tablets, and laptops).
+
+**Client** &#8658; _Internet_ &#8658; **Tailscale Funnel** (TCP proxy) &#8658;
+_VPN_ &#8658; **Tailscale Proxy** (HTTPS proxy) &#8594; **HA** (HTTP web-server)
+
+Without the Tailscale Funnel feature, you will be able to access your Home
+Assistant instance only when your devices (for example, phones, tablets, and laptops)
+are connected to your Tailscale VPN, there will be no Internet &#8658; VPN TCP
+proxying for HTTPS communication.
+
+More information: [Tailscale Funnel][tailscale_info_funnel]
+
+1. Navigate to the [Access controls page][tailscale_acls] of the admin console,
+   and add the below policy entries to the policy file. See [Server role

+         "attr": ["funnel"]
+       }
+     ]
+   }
+   ```
+
+1. Restart the add-on.
+
+**Note**: _After initial setup, it can take up to 10 minutes for the domain to
+be publicly available._
+
+**Note:** _You should not use any port number in the URL that you used
+previously to access Home Assistant. Tailscale Funnel works on the default HTTPS

 are running your own Tailscale control server, for example, a self-hosted
 [Headscale] instance.
 
+### Option: `userspace_networking`
+
+The add-on uses [userspace networking mode][tailscale_info_userspace_networking]
+to make your Home Assistant instance (and optionally the local subnets)
+accessible within your tailnet.
+
+When not set, this option is enabled by default.
+
+If you need to access other clients on your tailnet from your Home Assistant
+instance, disable userspace networking mode, which will create a `tailscale0`
+network interface on your host.
+
+If you want to access other clients on your tailnet even from your local subnet,
+execute steps 2 and 3 as described on [Site-to-site
+networking][tailscale_info_site_to_site].
+
+In case your local subnets collide with subnet routes within your tailnet, your
+local network access has priority, and these addresses won't be routed toward
+your tailnet. This will prevent your Home Assistant instance from losing network
+connection. This also means that using the same subnet on multiple nodes for load
+balancing and failover is impossible with the current add-on behavior.
+
+### Option: `proxy`
+
+When not set, this option is enabled by default.
+
+Tailscale can provide a TLS certificate for your Home Assistant instance within
+your tailnet domain.
+
+This can prevent browsers from warning that HTTP URLs to your Home Assistant instance
+look unencrypted (browsers are not aware of the connections between Tailscale
+nodes are secured with end-to-end encryption).
+
+More information: [Enabling HTTPS][tailscale_info_https]
+
+1. Configure Home Assistant to be accessible through an HTTP connection (this is
+   the default). See [HTTP integration documentation][http_integration] for more
+   information. If you still want to use another HTTPS connection to access Home
+   Assistant, please use a reverse proxy add-on.
+
+1. Home Assistant, by default, blocks requests from reverse proxies, like the
+   Tailscale Proxy. To enable it, add the following lines to your
+   `configuration.yaml`, without changing anything:
+
+   ```yaml
+   http:
+     use_x_forwarded_for: true
+     trusted_proxies:
+       - 127.0.0.1
+   ```
+
+1. Navigate to the [DNS page][tailscale_dns] of the admin console:
+
+   - Choose a Tailnet name.
+
+   - Enable MagicDNS if not already enabled.
+
+   - Under HTTPS Certificates section, click Enable HTTPS.
+
+1. Restart the add-on.
+
+**Note:** _You should not use any port number in the URL that you used
+previously to access Home Assistant. Tailscale Proxy works on the default HTTPS
+port 443._
+
+### Option: `snat_subnet_routes`
+
+This option allows subnet devices to see the traffic originating from the subnet
+router, and this simplifies routing configuration.
+
+When not set, this option is enabled by default.
+
+To support advanced [Site-to-site networking][tailscale_info_site_to_site] (eg.
+to traverse multiple networks), you can disable this functionality. But do it
