 run Sphinx under nearly any operating system.
 
 I wrote most of the book under MacOS, but I'm confident it can be
-compiled without much effort under Linux as well.  In order to compile
-the complete version of the book, you need to have
-[OpenModelica](https://openmodelica.org/) and a bunch of other tools.
-Unfortunately, I've lost track of exactly what the dependencies are.
-
-For Ubuntu, the requirements are listed in [requirements.txt](requirements.txt)
-which you can install by doing:
-
-    $ cat requirements.txt | xargs sudo apt-get install
-
-In addition you will need an updated development version of
-[Pygments](http://pygments.org/). The easiest way is to install the updated
-version of Pygments from @dietmarw by doing:
-
-    $ sudo pip install --upgrade https://bitbucket.org/dietmarw/pygments-main/get/default.tar.gz
