Added more hopefully useful information.

We may want to start cutting things at some point - it looks more
complicated than it really is!

+  Many different installation options are possible; probably the minimal
+  semi-useful configuration would be to install Mininet itself, kernel
+  support if necessary, and either the reference OpenFlow switch or 
+  Open vSwitch. This could be installed as follows, for example:
+  
+  % sudo ~/mininet/util/install.sh -knvm
+  
+  Respectively, this installs kernel support, core mininet dependencies,
+  Open vSwitch, and the Open vSwitch kernel module. If a new kernel was
+  installed, then a reboot may be required.

   If you successfully used install.sh, congratulations! You're basically
   done. Proceed to step [6] for additional advice.
