Perhaps poorly translated, they call it the scrum guide in English

I don't know what parts you are talking about since you're not specific.

Furthermore. Kanban is just a method of keeping track of who does what and what the progress of that is. You can use kanban in waterfall. You can use kanban in scrum. No one is just using kanban and nothing else. As your post seems to think.
