V. nice I have two questions:

i) do we leave the citation part in README.md? I would vote yes ii) We used to credit ppl in our CHANGELOG.md (thanks @schackartk this is a nice addition), can we still do this with our release please system? Can we manually add an entry to CHANGELOG without that messing up its own system?

Agreed

We can manually edit the CHANGELOG after a release. That shouldn't stuff it up I think. Though I don't know much about release-please so maybe @johanneskoester can shed some light?
