How to customize NWBC for HTML Logon Screen?

Hi experts,

How do I customize the logon screen for NWBC HTML?

I am trying to look for answers and this is the closest I got.

I was assuming this would be easy similar to Enterprise Portal Logon Screen customization, but to no avail my problem is I have no SAP GUI background so I am not familiar on how to navigate here.

Please advise.

Thanks,

Vey
