+        ⚠️ Warning!
+
+        You need to change at least change the mandatory parameter `WG_HOST` for this app to work properly.
+        It's value has to be a domain (or an IP address) that points to this server (accesible from WAN).
+
+        Same applies to the `WG_PORT` parameter. Change it to the port accessible from outside your LAN if it differs from the default 51820.
