+
+Please modify the `.env` file as needed for your use case.
+
+## Configuration
+
+### Configure LAN DNS Resolution
+
+Lines starting with `address` in the `dnsmasq.conf` file will be parsed as LAN DNS resolution rules.
+
+```conf
+address=/example.com/192.168.1.123
+```
+
+Router Configuration:
+
+- Set the gateway to the router IP
+- Bind the server IP address and MAC address, or assign a static IP address
+- Configure the DHCP server to use the server IP address as the DNS server
+
+## Volumes
+
+- `dnsmasq.conf`: Configuration file for DNSMasq (mounted to `/etc/dnsmasq.conf`).
+
+## Ports
+
+- `53/tcp`: DNS service (TCP)
+- `53/udp`: DNS service (UDP)
+
+## Security Notes
+
+- This service requires `NET_ADMIN` and `NET_BIND_SERVICE` capabilities to bind to privileged ports.
+- Ensure proper firewall rules are in place to restrict access to the DNS service.
