[TYPO3] Typo3 4.0 Install Problems

[Amir M.]

In my last email here I was referred to the current Installation guide. 
  But for some reason, I think this install guide is a bit too old for 
4.0 and is confusing me already.

For one, the directories that is supposed to be replaced in step 2 are 
not provided in the Typo3 4.0 src zip.  Am I missing something here?

Are we to replace just what is in the Typo3 4.0 src?  Btw, I believe I 
am upgrading from 3.8.
