+## 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 crypto-square.spec.js
