I was trying asciinema, and to test it I recorded this video. If you want to try Haskell Stack just type this in your terminal

$ wget -qO- https://get.haskellstack.org/ | sh

or follow the install instructions on their webpage.

Stack is a cross-platform program for developing Haskell projects. You can use templates to create new projects. In order to start a new project type:

$ stack new [name of the project] [name of the template (optional)]

Here you can watch it in action.
