Help me learn to use CKEditor

I am attempting to install and integrate CKEditor on my website. My employer requires me to use this program and I am trying to learn it. I am a technical writer, and am somewhat familiar with CLI commands in Unix, Linux and C++, but I DO NOT read or write code. You will probably have to explain stuff that seems very basic to you. For this project I am using an iMac running Mac OS 10.5.8. To write my HTML pages I use Kompozer. My FTP program is Cyberduck. My website is hosted by MacHighway. I know basic HTML and can hand-code web pages if I have to. I have downloaded CKEditor 4.1.2 Standard and unzipped it. I uploaded the files to a ckeditor directory as instructed. The sample files work fine. That's as far as I have gotten. I cannot get the editor window to appear. I don't understand how this program is supposed to work. The documentation is written by idiots; as a professional technical editor, I give it an F. What I need: How do I use this program? How do I get the CKEditor window to appear on a page in a browser? How do I save my changes? Do I have to change every single one of my current pages to include a command, in order to use CKEditor? How do I keep strangers from editing those pages that have CKEditor on them? What I do not need: Information on how to enter or format text, etc. What I've seen of the CKEditor editing window looks very much like the edit window in Wikipedia, and I know how to use that. I suspect that I can learn all of this in a couple of 8 hour days, with the right help.
