GIPS - Help

In schweser book number 5, at the bottom on page 235 in the GIPS core-concepts portion, there are few points that talk about private equity valuation mandatory guidelines. I never came across these points in the reading (in schweser). And Schweser talks about real-estate and private equity first. Then it mentions few other topics and again discusses real estate and private equity. I’m a little confused and find all these provisions getting mixed up. Can somebody please outline what all covers private equity and real estate and how to go about it. Thanks.

I’m not asking anybody to write a whole summary. Just how to go about it.
