Trivial change to the Getting Started Guide

I had a user run through the Getting Started Guide (again), and the only thing I saw is that the sentence "Open the file can.ex2 from the Examples Directory" is somewhat confusing (for someone learning lots of foreign stuff). Please change it to: "From the Examples Directory, open the file can.ex2".

Also, please take a new screenshot for paragraph 2, which includes the Examples directory on the left, and the files in Examples on the right.
