+.SH NAME
+mdassemble \- assemble MD devices
+.I aka
+Linux Software Raid.
+
+.SH SYNOPSIS
+
+.BI mdassemble
+
+.SH DESCRIPTION 
+.B mdassemble
+is a tiny program that can be used to assemble MD devices inside an
+initial ramdisk (initrd) or initramfs, it is meant to replace the in-kernel
+automatic raid detection and activation.
+It can be built statically and linked against lightweight libc alternatives, like
+.B dietlibc,
+.B klibc
+or
+.B uClibc.
+
+.SH USAGE
+Invoking
+.B mdassemble
+has the same effect as invoking
+.B mdadm --assemble --scan.
+
+.SH OPTIONS
+
+There are no options to
+.B mdassemble.
+
+.SH FILES
+
+.SS /etc/mdadm.conf
+
+The config file lists which devices may be scanned to see if
+they contain MD super block, and gives identifying information
+(e.g. UUID) about known MD arrays.  See
+.BR mdadm.conf (5)
+for more details.
+
+.B mdassemble
+supports all configuration parameters defined in
+.B mdadm.conf
+with the exception of
+.B auto=
+which is supported only if mdadm was built with the 
+.B -DMDASSEMBLE_AUTO
+define.
