We are almost there! The following steps are missing:

    $ cd hello

Then configure your database in config/dev.exs and run:

    $ mix ecto.create

Start your Phoenix app with:

    $ mix phx.server

You can also run your app inside IEx (Interactive Elixir) as:

    $ iex -S mix phx.server

[postgres       ] This user must also own the server process.
[postgres       ]
[postgres       ] The database cluster will be initialized with locale "C".
[postgres       ] The default text search configuration will be set to "english".
