In step 12 and 13, the script to create the install-config.yaml and agent-config.yaml file does not work.
1. here-doc EOF at the end of the script is not in column 1, but indented, so it does not actually save the doc and return to the command line. The user needs to enter "EOF" in column 1 to save the file, and get back to the command prompt.
2. The here-doc assumes there is a directory call my-cluster,

 which may not conform to the user's naming convention. Just drop the directory, and create it in the current directory.

always

1. click the copy script icon in the top of the 
2. paste the script into your command line.

1. script is not saved, because EOF is incorrect.
2. when user enters "EOF", script fails because "my-cluster" directory dows not exist.

the pasted install-config.yaml is created in local directory.

I've seen this "EOF" problem before in other OCP doc scripts, it's likely broken on other pages.
