Let's read the whole installation script to get a general understanding of its purpose and how it works (bash script and standard packages). Perform the installation (You will get a simple and hackable Haskell IDE, specialized for HaskellKatas). Let's take a look at the program (newk) and perform a kata routine focused on reformatting and refactoring simple code in order to discover elements and connections between them. Hackathon friendly, in a really new way ;-)
