+.Ss BUILDING AUTOMATIC INSTALL MEDIA
+If building automatic install media, use tar to extract a release ISO:
+.Dl mkdir release-media
+.Dl tar xvf -C release-media FreeBSD-13.0-RELEASE-amd64-disc1.iso
+.Pp
+Then place a script as above in
+.Pa etc/installerconfig
+.Pp
+This directory can then be used directly as an NFS root for
+.Xr diskless 8
+installations or it can be rebuilt into an ISO image using the release scripts in
+.Pa /usr/src/release .
+For example, on amd64:
+.Dl sh /usr/src/release/amd64/mkisoimages.sh -b '13_0_RELEASE_AMD64_CD' output.iso release-media
