 Run-length encoding (RLE) is a simple form of data compression, where runs
 (consecutive data elements) are replaced by just one data value and count.
 
 For example we can represent the original 53 characters with only 13.
 
-```
+```text
 "WWWWWWWWWWWWBWWWWWWWWWWWWBBBWWWWWWWWWWWWWWWWWWWWWWWWB"  ->  "12WB12W3B24WB"
 ```
 
 RLE allows the original data to be perfectly reconstructed from
 the compressed data, which makes it a lossless data compression.
 
-```
+```text
 "AABCCCDEEEE"  ->  "2AB3CD4E"  ->  "AABCCCDEEEE"
 ```
 
 For simplicity, you can assume that the unencoded string will only contain
-the letters A through Z (either lower or upper case) and whitespace. This way 
-data to be encoded will never contain any numbers and numbers inside data to 
+the letters A through Z (either lower or upper case) and whitespace. This way
+data to be encoded will never contain any numbers and numbers inside data to
 be decoded always represent the count for the following character.

-## 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 run-length-encoding.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`.
