+.Sh NAME
+.Nm mainbus
+.Nd device tree root
+.Sh SYNOPSIS
+.Cd "mainbus0 at root"
+.Sh DESCRIPTION
+.Nm
+provides an abstraction for all system buses to attach to.
+It is the start of the device tree and always attached.
+It is not a physical device as such,
+but an abstraction to which other devices may attach.
+.Pp
+The actual buses which attach are largely machine-dependent;
+refer to the individual man pages for more information.
