Linux Redhat 8 Install

[Gosha1985]

I am in the middle of downloading the RedHat 8 distribution which consists of 5 CDs. 3 of them, I've heard, are essential and the rest 2 are just some extra useful apps. My question is can I install first 3 CD and then after (whenever I choose) install the 2 remaining ....or all 5 CDs have to be installed at once?
Thank you.

you need the first 3 for gui installation. and all the personal apps are on these

The other 2 can be downloaded at any time but i bet you do not need them unless you plan on using it as a server.
