   If you are running Ubuntu 10.04 or Debian Lenny, you may be able to use the
   util/install.sh script to install a compatible Linux kernel as well as
   other software including the OpenFlow reference implementation, the Open
-  vSwitch switch implementation, and the NOX OpenFlow controller. Assuming
-  the mininet source tree is installed in ~/mininet, the steps to run
-  install.sh are as follows:
+  vSwitch switch implementation, and the NOX OpenFlow controller. 
 
+  Many different installation options are possible by passing different
+  options to install.sh; install.sh -h lists them all.
+  
+  Assuming the mininet source tree is installed in ~/mininet, the steps to run
+  install.sh to install everything we use for OpenFlow tutorials are:
+  
   % cd
-  % time ~/mininet/util/install.sh
+  % time ~/mininet/util/install.sh  # installs tons of stuff
   % sudo reboot  # to load new kernel
   % ~/mininet/util/install.sh -c  # to clean out unneeded kernel stuff
 
   This installs a lot of useful software, but it will take a while (20
   minutes or more, depending on your network connection, computer, etc..)

-  If install.sh cannot be used for some reason, or if you don't want to
-  install all of these components (they're useful!), the kernel and
-  OpenFlow software requirements are descibed in steps [3] and [4],
-  which follow.
  
-  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:

   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.

   For Ubuntu and Debian, we provide a 2.6.33 kernel package which you may be
