 ndnSIM source code should be placed in ``src/ndnSIM`` folder under NS-3 simulator source tree.  For example::
 
 	cd ns-3-dev
-	git clone git@github.com:NDN-Routing/ndnSIM.git ns-3/src/ndnSIM
+	git clone git://github.com/NDN-Routing/ndnSIM.git ns-3/src/ndnSIM
 
 After cloning, a number of patches need to be applied to the base NS-3 to make sure ndnSIM compiles and works::

 The first command is to create a directory, which will contain everything NS-3 related.  The bare minimum is just base NS-3 (the first clone above). The second clone gets a module necessary to build python bindings, which are necessary for the visualizer module.  The third clone gets actual ndnSIM code and places it in src/ directory.
