Description of problem:

There is a bunch of unnecessary and unimportant information for
users which are going to build stack system or thinking of using
RHEL OSP:

    https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux_OpenStack_Platform/7/html/Director_Installation_and_Usage/chap-Installing_the_Undercloud.html

Here is one of example:

Any parameter explanation like masquerade_network, is not actually
important to users.

    https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux_OpenStack_Platform/7/html/Director_Installation_and_Usage/sect-Configuring_the_Director.html

Are there any instruction just for quick installation without any
details like any kind of explanations?

Just like, do this, do that, that's it.

If I've missed anything which you've already made for beginners,
please point it out to me.
