 In this exercise, if you do not know about it already, you will learn about the rotational cipher "ROT13".
 
-A ROT13 on the Latin alphabet would be as follows:
-
-- Plain: abcdefghijklmnopqrstuvwxyz
-
+A ROT13 applied the Latin alphabet:
+```
+- Plain:  abcdefghijklmnopqrstuvwxyz
+          ||||||||||||||||||||||||||
 - Cipher: nopqrstuvwxyzabcdefghijklm
+```
 
-Your purpose in this exercise is to create a similar `rotate` function that is a better version of the ROT13 cipher.
-
-Your function will receive a `string` and a `number` and it will rotate each letter of that `string` by the `number` of times settled by the second argument towards the right, or towards the left if the number is negative.
-
-Your `function` should only rotate letters. If the string includes punctuation and numbers
-they will remain the same.
+You will create a similar `rotate` function that is a better version of the ROT13 cipher.
 
-### Notions
+Your function will receive a `String` and an `i8`, and will rotate each letter of that string by the number of times described by the second argument. Positive numbers rotate to the right, negative numbers rotate to the left.
