 ## Network boot
 In order to be able to test different kernels and rootfs network boot can be easily enabled in U-Boot by setting the default `bootcmd` to either `bootcmd_dhcp` or `bootcmd_pxe`. In order for this to work, Rock Pi 4 should be connected to a LAN which provides DHCP, TFTP and NFS server.
 
+You can use the `setup-tftp-nfs.sh` script within the `scripts` folder as reference or to generate a TFTP & NFS server on a Debian/Ubuntu system.
+
+```bash
+# Replace 4a with your Rock Pi model
+# Replace eth0 with the network device you use (script fetches IP and subnet mask from it)
+./scripts/setup-tftp-nfs.sh 4a eth0
+```
+
 The following example shows TFTP configuration to enable PXE boot.
 
 The files are placed inside /srv/tftp
