 ndnSIM uses standard NS-3 compilation procedure.  Normally the following commands should be sufficient to configure and build ndnSIM with python bindings enabled::
 
 	cd <ns-3-folder>
-	./waf configure --enable-examples --enable-ndn-plugins=topology,mobility
+	./waf configure --enable-examples
 	./waf
 
 On MacOS (with macports), you may need to modify the configure command to use macports version of python::
 
 	cd <ns-3-folder>
-	./waf configure --with-python=/opt/local/bin/python2.7 --enable-examples --enable-ndn-plugins=topology,mobility
+	./waf configure --with-python=/opt/local/bin/python2.7 --enable-examples
 	./waf
 
 Python bindings is an optional and not very stable feature of NS-3 simulator.  It is possible to disable python bindings compilation either to speed up compilation or to avoid certain compilation errors (e.g., "Could not find a task generator for the name 'ns3-visualizer'")::
 
 	cd <ns-3-folder>
-	./waf configure --disable-python --enable-examples --enable-ndn-plugins=topology,mobility
+	./waf configure --disable-python --enable-examples
 	./waf
 
 For more configuration options, please refer to ``./waf --help``.

-ndnSIM contains a number of NS-3 extensions that are not technically part of the ndnSIM.  Right now there are two optional plugins---topology and mobility---which can be enabled using the following configuration option::
