Looks good to me. Just a few minor things:

• Update readme with new instructions for local testing
• Update login button with orcid button
• Fix some minor hiccups encountered when testing during meeting

Codewise this looks good to me. I am working through poetry to try to get the dependencies installed so I can test it again before merging.

One more recommendation is just to rebase from master / merge with master so that some of the files (eg. README) is updated.

Mostly seems fine to me - is it possible to clarify the instructions for redirecting the urls within orcid.py? Eg. Adding the local testing URI (eg. localhost:<port> or 127.0.0.1:<port>) on the orcid side. Got stuck here for a minute. I added this into the README.

I also added in FLASK_APP to the .env.template file, otherwise it keeps asking for the missing variable.

Otherwise, looks good to merge to me. Maybe we can hold off on merging it until we've chatted about setting up a staging + production heroku app.
