       <p style="padding:0.2em"> With a working internet connection, you can run

         This will try to install MathJax into the directory where you installed
         IPython. If you installed IPython to a location that requires
         administrative privileges to write, you will need to make this call as
         an administrator. On OSX/Linux/Unix, this can be done at the
         command-line via:
