Describe your suggestion

In the Wikipedia example on the page it mentions that a Caesar Cipher uses a left shift.

The example from the project page which shows a right shift of 5:

  > caesar_cipher("What a string!", 5)
  => "Bmfy f xywnsl!"

I propose:

• explicitly state to use a right shift in the project instructions
• note that the wikipedia article uses a left shift

• Path
