anchor.diff:  
   You will do the exercises in part 2 on the main server, not your VM.
   
  -**Set up Github.com & fork this lab**
  +**Set up Github.com & fork the sample repo**
   
   Go to http://github.com and set up a user account. You probably do NOT want to use your St. Thomas email address for this, as your Github account may be an asset throughout your career. Choose a suitably professional user name.
   
  
positive.code: 
  * Directory H should contain directories J and K
  
  
  Every directory should have a file in it, with the letter of the directory doubled in lower case. E.g., directory A should have aa, F would have ff, etc.
  
  **Install and use tree**
  
  First, install tree
  
      vagrant@precise64~: sudo apt-get install -y tree
  
  NOTE: The "-y" is critical, as this makes it possible to script apt-get
  
  If you get any kind of access or permissions error, please be sure you are in YOUR vagrant machine, not the main course server (where you do not have permissions to install things.) Re-read the above material carefully.
  
  
negative.code: 
  You will do the exercises in this part on your new Vagrant VM.
  
  Using the skills you learned in the previous lab (in particular, the mkdir, cd, and touch commands),  perform the following steps:
  
  **Configure a directory structure**
  
  * First, create directories A, C, D, and H all at the same level
  
  * Directory A should contain sub-directories named B, C and D
  
  * Directory C should contain directories E and F
