The leveling guide is step by step directions starting in Stormwind or Orgrimmar and ending with the last quest in the chain. Every quest is included in the guide so you will earn the Quest Achievement for Mount Hyjal (Coming Down the Mountain).
There are no strings attached. A PDF file is embedded onto the webpage above. All you have to do is click and view! There are no ads, no signing up, nothing like that.
Instructions on managing and using the PDF file are either on the webpage itself or inside the PDF.
On that note, I am having issues getting the PDF to show up in Internet Explorer (At least IE8 and IE9b). It works perfectly fine in Firefox and Chrome. If anyone knows a possible fix to make it work in IE, I would greatly appreciate it!
If you have any questions or find any mistakes, please let me know! Thanks.
