Did the man page not help?  I've found it to be pretty complete.

This is pretty simple:
	The current time is 13:15:24
	The box has been online 15 days, 4 hours, 16 minutes.
	The 1, 5, and 15 minute loads are 0.58, 0.45, and 0.40 respectively.

There are 168 total processes.  Of those
	2 are actively doing something
	The rest are idle (sleeping)

The CPU was 90% idle over the last update period.  About 8% was devoted to
user processes (probably the two mentioned before), and about 2% was devoted
to kernel time.

You have 3GB of RAM and it is almost all used, either by processes, or disk
buffers and file cache.  There's about 32MB of free memory.  You do not have
any swap space configured.
