Developers pages for CodeReady Studio [0] contain outdated information.

Section 1:
"You may install Red Hat CodeReady Studio standalone (A), or also install it with Red Hat JBoss Enterprise Edition (B)."

I think this is not precise as of the getting started content. I would rephrase it:
"Install Red Hat CodeReady Studio standalone (A) and install and start with Red Hat JBoss EAP (B)"

Ie. section 1. A. 1: Suggests to use Java 8, but that is not true anymore, Java 11 is supported minimal version, see [1]. And I would recommend using OpenJDK only.

Section 3: What is JBoss EAP? - Link does not work.
