Where to find the issue

n/y

Describe the issue

There is not documentation reg. the vaccination certificate implementation inside of the Corona-Warn-App published yet.

Suggested change

Publish a document describing the implementation of vaccination certificates in the upcoming version 2.3 of the Corona-Warn-App, similar to https://github.com/corona-warn-app/cwa-documentation/blob/master/event_registration.md which was published before the release of version 2.0 describing the implementation of the event-registration feature.

Seems like this won't be done. It makes no sense to leave this issue open any longer.
