+# 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
+
+There are two different methods of getting set up to run the tests with Objective-C:
+
+- Create an Xcode project with a test target which will run the tests.
+- Use the ruby gem `objc` as a test runner utility.
+
+Both are described in more detail here: http://help.exercism.io/getting-started-with-objective-c.html
+
+
+### Submitting Exercises
+
+When submitting an exercise, make sure your solution file is in the same directory as the test code.
+
+For example, if you're submitting `Bob.m` for the Bob exercise, the submit command would be something like `exercism submit <path_to_exercism_dir>/objective-c/bob/Bob.m`.
