 ## Installation
 
 First, you need to install the wkhtmltopdf command line tool on your system.  The easiest way to do this is to
-[download](http://code.google.com/p/wkhtmltopdf/downloads/list) a prebuilt version for your system.  There are 
-various platform specific issues to worry about.  I've found that the 0.11 version of wkhtmltopdf produces PDFs
-without selectable text or clickable links on OS X, and some versions require an X server and others do not.
-
-From my experimentation, the best versions are as follows:
-
-* On OS X, I use [version 0.10](http://code.google.com/p/wkhtmltopdf/downloads/detail?name=wkhtmltopdf-OSX-0.10.0_rc2-static.tar.bz2&can=2&q=).
-* On Ubuntu, I use [version 0.9.9](http://code.google.com/p/wkhtmltopdf/downloads/list) 32 or 64 bit from that page.  Don't try to use
-the version installed via `apt-get` because it is missing features and requires and X server.  Follow 
-[this guide](http://wingdspur.com/2012/12/installing-wkhtmltopdf-on-ubuntu/) to make sure you have all the necessary dependencies.
-
-Although those versions are somewhat old, they have worked the best for me.

 Finally, to install the node module, use `npm`:
