Is there any documentation on Splunk Enterprise Security that we can use?

This is nuts, I downloaded the ES 4.1.1 Overview and it's two pages basically telling me how to login. No kidding. HP has too much with ArcSight (which is better than nothing) and this is the overview provided by Splunk to Enterprise clients? Seriously? Can someone please confirm this or provide additional documentation as to what we are looking at with some of these because we had professional services do an install into this and while they did a good job, there is minimal detail when it comes to random questions within. I don't want to open cases when they aren't needed and I will have plenty of users who won't learn Splunk language to use this product because that's not what they do. Thx
