Is there a posgres instance running locally?

One is needed to the quick startup with a database.

No, how can I run run a postgres instance?

When I type postgres I get:

postgres does not know where to find the server configuration file.

You must specify the --config-file or -D invocation option or set the PGDATA environment variable.

If you are running on Mac I highly recommend you to use the Postgres App https://postgresapp.com/ just install and run it. On other OSs you can search here https://www.postgresql.org/download/ .
