 Given two buckets of different size, demonstrate how to measure an exact number of liters by strategically transferring liters of fluid between the buckets.
 
 Since this mathematical problem is fairly subject to interpretation / individual approach, the tests have been written specifically to expect one overarching solution.
 
-To help, the tests provide you with which bucket to fill first. That means, when starting with the larger bucket full, you are NOT allowed at any point to have the smaller bucket full and the larger bucket empty (aka, the opposite starting point); that would defeat the purpose of comparing both approaches!

 Your program will take as input:
-- the size of bucket one, passed as a numeric value
-- the size of bucket two, passed as a numeric value
-- the desired number of liters to reach, passed as a numeric value
-- which bucket to fill first, passed as a String (either 'one' or 'two')
+- the size of bucket one
+- the size of bucket two
+- the desired number of liters to reach
+- which bucket to fill first, either bucket one or bucket two
 
 Your program should determine:
-- the total number of "moves" it should take to reach the desired number of liters, including the first fill - expects a numeric value
-- which bucket should end up with the desired number of liters (let's say this is bucket A) - expects a String (either 'one' or 'two')
-- how many liters are left in the other bucket (bucket B) - expects a numeric value
+- the total number of "moves" it should take to reach the desired number of liters, including the first fill
+- which bucket should end up with the desired number of liters (let's say this is bucket A) - either bucket one or bucket two
+- how many liters are left in the other bucket (bucket B)
 
-Note: any time a change is made to either or both buckets counts as one (1) move.

+Example:
 Bucket one can hold up to 7 liters, and bucket two can hold up to 11 liters. Let's say bucket one, at a given step, is holding 7 liters, and bucket two is holding 8 liters (7,8). If you empty bucket one and make no change to bucket two, leaving you with 0 liters and 8 liters respectively (0,8), that counts as one "move". Instead, if you had poured from bucket one into bucket two until bucket two was full, leaving you with 4 liters in bucket one and 11 liters in bucket two (4,11), that would count as only one "move" as well.
 
 To conclude, the only valid moves are:
 - pouring from one bucket to another
 - emptying one bucket and doing nothing to the other

-## 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 two-bucket.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`.
