+.Sh EXAMPLES
+To create a kernel with a ramdisk or MD file system, your kernel config
+needs the following options:
+.Bd -literal -ofset indent
+options 	MD_ROOT			#MD is a potential root device
+options		MD_ROOT_SIZE=8192	# 8MB ram disk
+makeoptions	MFS_IMAGE=/h/foo/ARM-MD
+options 	ROOTDEVNAME=\"ufs:md0\"
+.Ed
+The image in
+.Pa /h/foo/ARM-MD
+will be loaded as the initial image each boot.
+To create the image to use, please follow the steps to create a file-backed
+disk found in the 
+.Xr mdconfig 8
+man page.
+Other tools will also create these images, such as NanoBSD.
