How can i change the following things on NRichTextViewWithRibbon?

The name of the Ribbon Tab (Home, Insert, ...)
Add new Ribbon Tab
Add and remove items from Ribbon Group

Are there any full running example of the Rich Text Editor with Ribbon? Not with NRichTextViewWithRibbon but step by step.
I am new in that and need to know how to build it by myself.
Perhaps there is a pre NRichTextViewWithRibbon version from a earlier version of Open Vision Rich Text Editor.
