 1 | # CheggRipper
 2 | This script gets the Chegg solutions for any given textbook and outputs all of them to a simple html document. 
 3 | It is intended to be automatic, once I get it to work that way but for now you can:
 4 | 
 5 | Find a textbook you want all the solutions for and navigate to the first question in the first chapter.
 6 | In chrome console, copy/paste the two functions at the top and enter them into the console.
 7 | Then follow the directions in the script.
