## Elm Installation
Refer to the [Exercism help page](http://exercism.io/languages/elm) for Elm
installation and learning resources.
## Writing the Code
The first time you start an exercise, you'll need to ensure you have the
appropriate dependencies installed.
```bash
$ elm-package install --yes
```
Execute the tests with:
```bash
$ elm-test
```
Automatically run tests again when you save changes:
```bash
$ elm-test --watch
```
As you work your way through the test suite, be sure to remove the `skip <|`
calls from each test until you get them all passing!
