# Hello World

Welcome to Hello World on Exercism's Clojure Track.
If you need help running the tests or submitting your code, check out `HELP.md`.

## Instructions

The classical introductory exercise. Just say "Hello, World!".

["Hello, World!"](http://en.wikipedia.org/wiki/%22Hello,_world!%22_program) is
the traditional first program for beginning programming in a new language
or environment.

The objectives are simple:

- Write a function that returns the string "Hello, World!".
- Run the test suite and make sure that it succeeds.
- Submit your solution and check it at the website.

If everything goes well, you will be ready to fetch your first real exercise.

## Project Structure

Clojure exercises in exercism use [leiningen](http://leiningen.org/) to configure and run your code
and use [leiningen standard directory structure](https://github.com/technomancy/leiningen/blob/master/doc/TUTORIAL.md#directory-layout).

You will find a test file named `hello_world_test.clj` inside `test` directory.
Write your code in `src/hello_world.clj`. It should use the namespace `hello-world` so that tests can pick it up.

## Running tests

Run the tests using `lein test` command and make them pass:

```
$ lein test

lein test hello-world-test

Ran 3 tests containing 3 assertions.
0 failures, 0 errors.
```

Then submit the exercise using:

```
$ exercism submit src/hello_world.clj
```
