Introduction and Overview
=========================
-TBD
+The Linux FireWire subsystem adds some interfaces into the Linux system
+to use/maintain any resource on the IEEE 1394 bus.
+
+The main purpose of these interfaces is to access address space on each node
+on the IEEE 1394 bus by ISO/IEC 13213 (IEEE 1212) procedure, and to control
+isochronous resources on the bus by IEEE 1394 procedure.
+
+Two types of interfaces are added, according to consumers of the interface. A
+set of userspace interfaces is available via `firewire character devices`. A set
+of kernel interfaces is available via exported symbols in the `firewire-core`
+module.
