+# Hello World
+
+Write a function 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
+
+Write a `Hello World!` function that can greet someone given their name.
+The function should return the appropriate greeting.
+
+For an input of "Alice", the response should be "Hello, Alice!".
+
+If a name is not given, the response should be "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 (`exercism submit /path/to/file`)
+
+## 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 not be reviewed by a person, but by rikki- the robot, who will offer an encouraging word.
+
+## Making the Test Suite Pass
+
+1. Get [PHPUnit].
+
+        % wget --no-check-certificate https://phar.phpunit.de/phpunit.phar
+        % chmod +x phpunit.phar
+
+2. Execute the tests for an assignment.
+
+        % phpunit.phar wordy/wordy_test.php
+
+[PHPUnit]: http://phpunit.de

+## Source
+
+This is an exercise to introduce users to using Exercism [http://en.wikipedia.org/wiki/%22Hello,_world!%22_program](http://en.wikipedia.org/wiki/%22Hello,_world!%22_program)
+
+## Submitting Incomplete Problems
+It's possible to submit an incomplete solution so you can see how others have completed the exercise.
