+This module is a very simple fake I2C/SMBus driver.  It implements four
+types of SMBus commands: write quick, (r/w) byte, (r/w) byte data, and
+(r/w) word data.
 
 No hardware is needed nor associated with this module.  It will accept write
 quick commands to all addresses; it will respond to the other commands (also
 to all addresses) by reading from or writing to an array in memory.  It will
 also spam the kernel logs for every command it handles.
 
+A pointer register with auto-increment is implemented for all byte
+operations.  This allows for continuous byte reads like those supported by
+EEPROMs, among others.
+
 The typical use-case is like this:
        1. load this module
        2. use i2cset (from lm_sensors project) to pre-load some data
