[webauthn] Explainer or more examples?

bfgeek has just created a new issue for 
https://github.com/w3c/webauthn:

== Explainer or more examples? ==
So while trying to understand this API I needed to open up Edge's 
guide to the slightly older API.
https://developer.microsoft.com/en-us/microsoft-edge/platform/documentation/dev-guide/device/web-authentication/

Is an explainer / examples in the github which have more fleshed out 
examples (like in the above link possible)?

Somewhat difficult to understand with just the client snippet, not a 
lot of context. :)
