If you’re curious about the SAML metadata libraries I’m releasing you can try them out without any fuss (if you have Docker installed) by typing

docker run -p 127.0.0.1:8080:8080 -p 127.0.0.1:8081:8081 --pull always digitalidentity/smee_live

Open the URL shown in the terminal, then click on the Open button and choose a notebook. I’ve bundled examples into a LiveBook along with the extra Linux bits needed.
