How to connect Ext Js 7.1 via cdn?

Set the startup project Ext Js via npm, but there is a big mess in the project structure.
I'm not sure what is going where and how to work with it.
So I want to start simple to connect via the cdn.
Anyone tell me the link? Nowhere not found.
And the normal materials in order to understand this framwork. In a network anything plainly not.
