-# Pascals Triangle
+# Pascal's Triangle
 
 Compute Pascal's triangle up to a given number of rows.
 
 In Pascal's Triangle each number is computed by adding the numbers to
 the right and left of the current position in the previous row.

-## 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 pascals-triangle.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`.
