Thanks. This comment prompted a discussion on how to improve the initial developer experience. The readme definitely needs a tidy up. We tend to assume that anyone interested in building it will be a moderately experienced Unity developer - but I think it's worth reexamining this assumption.

(It's a brave soul who tackles a codebase of this complexity as their first Unity project! But it was my first big Unity codebase and it was a great way to get myself out of the training pool)
