Where can I find documentation on Ext.nd?

Question

JavaScript

While working on adapting the lotus notes databases for the web, I found the Ext.nd
framework. There are a couple of html files with documentation in the archive, but they consist of links. The main ones (tutorials/faq) don't work.
On the official website sencha.com, a similar picture . There are links to the documentation, but they are broken.
I believe that the documentation on these links was once located, but then was removed. Couldn't find it with a google search. I asked on the official forum, but there is no answer yet.
Interested in a list of classes with methods, and tutorials (getting started).
Maybe someone has kept it? Or does anyone know where to find it.
Thank you.
