So how do you use it?

It's not clear from the readme.

I see you've got some scripts for creating the databases but nothing that indicates how you integrate this with a Core website.

This project is purely to highlight how to customise Identity and use different databases. Now that you ask the question, I think I can improve by showing a simple example of how this is integrated into an actual AspNetCore website.

For now, I do have an example in another project:

notworx-aspnetcore

Hope that helps.

I'll keep an eye out for the integration sample.
