 # Pythagorean Triplet
 
 A Pythagorean triplet is a set of three natural numbers, {a, b, c}, for
 which,
 
-```
+```text
 a**2 + b**2 = c**2
 ```
 
-For example, 
+For example,
 
-```
+```text
 3**2 + 4**2 = 9 + 16 = 25 = 5**2.
 ```
 
 There exists exactly one Pythagorean triplet for which a + b + c = 1000.
 
 Find the product a * b * c.

-## Making the Test Suite Pass
+## Running the test suite
 
-Execute the tests with:
+The provided test suite uses [Jasmine](https://jasmine.github.io/).
+You can install it by opening a terminal window and running the
+following command:
 
-    jasmine <exercise-name>.spec.js
+```sh
+npm install -g jasmine
+```
 
-Replace `<exercise-name>` with the name of the current exercise. E.g., to
-test the Hello World exercise:
+Run the test suite from the exercise directory with:
 
-    jasmine hello-world.spec.js
+```sh
+jasmine pythagorean-triplet.spec.js
+```
 
-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`.
+In many test suites all but the first test have been marked "pending".
+Once you get a test passing, activate the next one by changing `xit` to `it`.
