How do you define your audience/"user requirements" in your docs, to the reader?

[Leonard C. Porrello]

All,

I was wondering how to deal with the challenge of defining my target audience explicitly--in my docs, to the reader. I have hardware and software requirements, but I do not have "user requirements," nor do I have a clear idea of how to define my target user--to the reader. I have the standard, "This user's guide is intended for users and system administrators," and while "system administrators" is useful, "users" isn't saying much.

Thoughts? 

Thanks in advance!
