+## Rebuilding
+
+The iPXE binaries can be rebuilt with the `ipxe-update.sh`
+script. This script accepts command-line arguments that are passed to
+the underlying `make` process. e.g.,
+
+```bash
+echo "#!ipxe
+echo Tagging with vlan 1000
+vcreate --tag 1000 net0 autoboot || shell" >vlan-1000.ipxe
+
+sh ipxe-update.sh EMBED=$(readlink -f vlan-1000.ipxe)
