First you need to install Elm.
If you have npm, it's as easy as npm install -g elm.
When you are done you will have the following binaries in your path that we will make use of:
- elm-package
- elm-make
- elm-reactor
Run elm-reactor --port 8000 in this folder and go to http://localhost:8000 to have an Elm
environment up and running.
When you are starting out http://elm-lang.org/try is a great place to experiment.
