Instructions for Adding new datasources

[mandibuswell]

When holding a workshop, as the facilitator I would like to be able to create a datasource more relevant to my audience.
I would like to have instructions on how I can do that.

This may also make for a good extension exercise.

For example, Major League Ballparks are only in the US - in New Zealand if I had the right data source (and I would need to understand how to get one or make one) - I could change MLB parks for Rugby Stadiums for example.
