Add some instructions (e.g. including eScience attribution) and a request for users of the jupyterbook template to share back with our team their experience and use of the resource (both for attribution and creating a gallery).
Side note: there is no built-in way to track template usage in GitHub, but if you can search for a unique phrase within the template you'd be able to tell when others have cloned the repo.
@lsetiawan may have some ideas for how we can package the materials in a way that enables metric collection
