All that you require to do this course is to go to http://try.purescript.org in your favourite browser and be prepared to enter the rabbit's hole of functional programming in PureScript!!
Any idea why the purescript community still uses bower?

there is also a PureScript specific package management which is growing in popularity https://github.com/purescript/psc-package
It's a bit disappointing thee whole course is in the browser, one of the criticisms / difficulties of purescript is to get it running locally. The docs are improving but still a little involved, with many deps issues. It would have been great to see install instructions here too,
