Where is the quickstart for the custom login page (.net core) ?

Just wanted to have another look and compare the OpenID Connect vs the Custom Login page code and can’t seem to find it anymore?

I am pretty sure it was here: https://auth0.com/docs/quickstart/webapp/aspnet-core/v2/02-login-custom ?

Not sure why, but it looks like its moved out of the documentation pages, into github:
