Get started: clarify role of schema

In my opinion, we should more clearly explain in our get started guide - probably in the above file - that when a user changes their schema, this doesn't change the database - it's just the model that Prisma uses to build the client.

Improve this

Whenever you make changes to your Prisma schema in the future, you manually need to invoke prisma generate in order to accommodate the changes in your Prisma Client API.
