 If you want to build something using a Raspberry Pi, you'll probably use _resistors_.
 For this exercise, you need to know two things about them:
 
-* Each resistor has a resistance value.
-* Resistors are small - so small in fact that if you printed the resistance value on them, it would be hard to read.
+- Each resistor has a resistance value.
+- Resistors are small - so small in fact that if you printed the resistance value on them, it would be hard to read.
 
 To get around this problem, manufacturers print color-coded bands onto the resistors to denote their resistance values.
 Each band has a position and a numeric value.

 The band colors are encoded as follows:
 
-- Black: 0
-- Brown: 1
-- Red: 2
-- Orange: 3
-- Yellow: 4
-- Green: 5
-- Blue: 6
-- Violet: 7

 From the example above:
-brown-green should return 15
+brown-green should return 15, and
 brown-green-violet should return 15 too, ignoring the third color.
