Yes, what I have at the moment isn't very suited to people completely new to the field. The basic workflow is: plug your Garmin device into your computer, go to your user page (mine is http://www.cyclinganalytics.com/user/1000000), click the "Upload new rides" button, navigate to the Garmin device and find some ride files (probably stored in the "Activities" directory) and click okay.
Providing more information about how to get started with equipment and my site is a good idea and I'll look at doing something about that. Users having disposable income but not disposable time is a great point.
I'm not sure that you should explain how to do it, or even worry about my post. I may be a really limited number of potential users and you might have a much better way to spend your time.
If it were me, I'd focus on taking share to get a good number of users first, then worry about growing the market.
