Gladly there is an online IDE with compiler (https://repl.it/languages/haskell) so you don't even need to install Haskell locally (which honestly seemed a bit heavy for a starter's tutorial - "First you need Haskell Platform, then you can start the tutorial")

This is one of the better language tutorials on he web, IMO. It's very conversational, and if the FP concepts don't draw you in, wondering what stupid thing he's going to draw in the next chapter will.
