Stuck in the beginning

I am in the shameful state of getting stuck in the tutorial -

The configuration file was fine..
Ran the "Testing your intitial Pipeline" section and got a Manticore Socket Exception error
Realised, oh I need to install and run ElasticSearch as a prerequisite
The exception vanished, but the console is unresponsive when I execute
.. "Pipeline main started " displays, but no way to enter the curl command in the tutorial.

Any ideas on a solution? Are there some other prerequisites I am missing.

Just run the curl command from another terminal.

Ah so simple to fix
