 The Traefik labels configure a **TCP router** that:
-- Matches any request to `*.proxy.example.com` via SNI (Server Name Indication)
+- Catches any request not matched by higher-priority HTTP routers via `HostSNI(*)` (wildcard)
 - Uses the `websecure` entrypoint (port 443)
 - Passes the TLS connection through **without termination** (`tls.passthrough=true`)
 - Uses `priority=1` to avoid intercepting traffic meant for the main NetBird HTTP routers on the same entrypoint
 - Forwards traffic to the proxy container on port 8443
 
 <Note>
-Replace `proxy.example.com` in both the `NB_PROXY_DOMAIN` environment variable and the Traefik `HostSNI` rule with your actual proxy domain. These must match.
+The `HostSNI(*)` rule acts as a catch-all for any domain not matched by the existing NetBird HTTP routers. The `priority=1` ensures this TCP router only handles traffic that no other router claims. Any domain pointing to your server that isn't `netbird.example.com` will be forwarded to the proxy.

 ## Enable the Reverse Proxy Feature
 
-The quickstart installation does not include the [Reverse Proxy](/manage/reverse-proxy) feature by default. To enable it, you need to add the `netbird-proxy` container to your deployment and configure a separate proxy domain.
+When you select the built-in Traefik option (`[0]`), the script asks whether you want to enable the NetBird Proxy service:
+
+```
+Do you want to enable the NetBird Proxy service?
+The proxy exposes internal NetBird network resources to the internet.
+Enable proxy? [y/N]:
+```
+
+If you answer `y`, the script prompts for a **proxy domain**:
+
+```
+WARNING: The proxy domain MUST NOT be a subdomain of the NetBird management
+domain (netbird.example.com). Using a subdomain will cause TLS certificate conflicts.
+
+Enter the domain for the NetBird Proxy (e.g. proxy.my-domain.com):
+```
 
 <Warning>
-The proxy domain **must not** be a subdomain of your NetBird management domain. For example, if your management server is at `netbird.example.com`, do not use `proxy.netbird.example.com`. Use a separate subdomain like `proxy.example.com` instead. Using a subdomain of the management domain causes TLS and routing conflicts between the proxy and management services.

-See the [Enable Reverse Proxy migration guide](/selfhosted/migration/enable-reverse-proxy) for step-by-step instructions on adding the proxy to an existing deployment, including token generation, Docker Compose configuration, and DNS setup.
+The script then automatically generates a proxy access token, creates a `proxy.env` configuration file, and starts the proxy container alongside the other services. Point a wildcard DNS record (`*.proxy.example.com`) to your server's IP address so that service subdomains resolve correctly.
+
+If you skipped the proxy during initial setup, you can add it later by following the [Enable Reverse Proxy migration guide](/selfhosted/migration/enable-reverse-proxy).
