+# Hello World
+
+Write a program that greets the user by name, or by saying "Hello, World!" if no name is given.
+
+["Hello, World!"](http://en.wikipedia.org/wiki/%22Hello,_world!%22_program) is the traditional first program for beginning programming in a new language.
+
+**Note:** You can skip this exercise by running:
+
+    exercism skip $LANGUAGE hello-world
+
+## Specification
+
+The `Hello World!` program will greet me, the caller.
+
+If I tell the program my name is Alice, it will greet me by saying "Hello, Alice!".
+
+If I neglect to give it my name, it will greet me by saying "Hello, World!"
+
+## Test-Driven Development
+
+As programmers mature, they eventually want to test their code.
+
+Here at Exercism we simulate [Test-Driven Development](http://en.wikipedia.org/wiki/Test-driven_development) (TDD), where you write your tests before writing any functionality. The simulation comes in the form of a pre-written test suite, which will signal that you have solved the problem.
+
+It will also provide you with a safety net to explore other solutions without breaking the functionality.
+
+### A typical TDD workflow on Exercism:
+
+1. Run the test file and pick one test that's failing.
+2. Write some code to fix the test you picked.
+3. Re-run the tests to confirm the test is now passing.
+4. Repeat from step 1.
+5. [Submit your solution](http://help.exercism.io/submitting-exercises.html).
+
+## Instructions
+
+Submissions are encouraged to be general, within reason. Having said that, it's also important not to over-engineer a solution.
+
+It's important to remember that the goal is to make code as expressive and readable as we can. However, solutions to the hello-world exercise will be not be reviewed by a person, but by rikki- the robot, who will offer an encouraging word.
+
+## Setup
+
+Go through the setup instructions for ECMAScript to
+install the necessary dependencies:
+
+http://help.exercism.io/getting-started-with-ecmascript.html
+
+## Requirements
+
+They are already described in the link above, but just as a
+quick reference:
+
+Install globally a tool to run [Gulp](http://gulpjs.com) if
+it is not installed yet:
+
+```bash
+$ npm install -g gulp-cli
+```
+
+Install assignment dependencies:
+
+```bash
+$ npm install
+```
+
+## Making the test suite pass
+
+Execute the tests with:
+
+```bash
+$ gulp test
+```
+
+In many test suites all but the first test have been skipped.
+
+Once you get a test passing, you can unskip the next one by
+changing `xit` to `it`.
