Documentation around some of the internals like app.services

[virajkanwade]

I am following https://github.com/Neoteroi/BlackSheepEmptyProject as a guide for a project.

But what I am unable to understand is in configure_services how do I configure postgres connection?

There is a note regarding using ServicesRegistrationContext, but can't seem to figure out how?

Also, I looked at blacksheep-sqlalchemy for reference. https://github.com/Neoteroi/BlackSheep-SQLAlchemy/blob/main/blacksheepsqlalchemy/__init__.py

But I could not understand what are all the app.services. functions?
app.services.add_instance
app.services.add_alias
app.services.add_scoped_by_factory

Having some documentation on the internals will help others add more features to blacksheep.

Thanks
