+## Description
+<section id='description'>
+
+Write a program that generates an array of integers from 1 to 100 (inclusive). But:
+<ul>
+    <li>for multiples of 3, add <code>"Fizz"</code> to the array instead of the number</li>
+    <li>for multiples of 5, add <code>"Buzz"</code> to the array instead of the number</li>
+    <li>for multiples of 3 and 5, add <code>"FizzBuzz"</code> to the array instead of the number</li>
+</ul>
+
+</section>
+## Instructions
+<section id='instructions'>
+
+Your program should return an array containing the results based on the rules above.
+</section>
+
+## Tests
+<section id='tests'>
+
+```yml
+tests:
+  - text: <code>fizzBuzz</code> should be a function.
+    testString: assert(typeof fizzBuzz=='function');
+  - text: <code>fizzBuzz()</code> should return an Array.
+    testString: assert(Array.isArray(fizzBuzz())==true);
+  - text: Numbers divisible by only 3 should return <code>"Fizz"</code>.
+    testString: assert.equal(fizzBuzz()[2], "Fizz");
+  - text: Numbers divisible by only 5 should return <code>"Buzz"</code>.
+    testString: assert.equal(fizzBuzz()[99], "Buzz");
+  - text: Numbers divisible by both 3 and 5 should return <code>"FizzBuzz"</code>.
+    testString: assert.equal(fizzBuzz()[89], "FizzBuzz");
+  - text: Numbers not divisible by either 3 or 5 should return the number itself.
+    testString: assert.equal(fizzBuzz()[12], 13);
