@ZkHaider which parts of the Fluent Postgres Driver are you wanting to document? For this repo, all the docs should be at https://docs.vapor.codes

+1 is not enough
Need more examples of how it can be used without vapor

Hi all, new to this driver and in walking through the documentation at

https://docs.vapor.codes/fluent/overview/

There is reference to using the connection as:

app.databases.use(.postgres(hostname: "localhost", username: "vapor", password: "vapor", database: "vapor"), as: .psql)

However this yields a deprecation warning as mentioned in:

#212

Are there plans to update these docs?

Great work on this project, I'm learning a lot and loving it!
