-<p>ndnSIM 2.0 is a new release of <a class="reference external" href="http://ndnsim.net/1.0/">NS-3 based Named Data Networking (NDN) simulator</a> that went through extensive refactoring and rewriting.  The key new features of the new version:</p>
-
-<ul class="simple">
-<li>ndnSIM no longer re-implements basic NDN primitives and directly uses implementation from <a class="reference external" href="http://named-data.net/doc/ndn-cxx/">ndn-cxx library (NDN C++ library with eXperimental eXtensions)</a>.</li>
-<li>All NDN forwarding and management is implemented directly using source code of <a class="reference external" href="http://named-data.net/doc/NFD/">Named
-Data Networking Forwarding Daemon (NFD)</a></li>
-<li>Packet format changed to the <a class="reference external" href="http://named-data.net/doc/ndn-tlv/">NDN packet format</a></li>
-</ul>
-
     <p>
 We invite you to <a href="http://www.lists.cs.ucla.edu/mailman/listinfo/ndnsim" target="_blank">join our mailing list</a> to see and participate in discussions about ndnSIM implementation and simulations in general (<a href="http://www.lists.cs.ucla.edu/pipermail/ndnsim/" target="_blank">mailing list archives</a>).

-
-.. note::
    If you do not have root permissions to install boost, you can install it in your home
    folder.  However, you need to be make sure that `libboost_iostreams` library is successfully
    compiled and is installed.  Please refer to :ref:`the following example <Installing boost

+**2. Dependencies for NS-3 Python bindings**
+
+If you are planning to use NS-3 python bindings, a number of additional dependencies
+should be installed.  For example, in order to run `visualizer`_ module, the following
+should be installed:
+
+- OS X
+
+  * OS X with MacPorts:
+
+    .. code-block:: bash
+

+
+    .. code-block:: bash

 Simulating using ndnSIM
 -----------------------
 
-- Examples simulations
+- Example simulation scenarios
 
-    When NS-3 is compiled with ``--with-examples`` flag, you can directly run all examples
-    described in :doc:`examples section of this tutorial <examples>`.  For example, to run
-    ``ndn-simple.cpp`` scenario, you can run the following command:
-
-    .. code-block:: bash
-
-        ./waf --run=ndn-simple
-
-    To run ``ndn-grid.cpp`` scenario:
-
-    .. code-block:: bash
-
-        ./waf --run=ndn-grid
-
-    To run the sample simulation scenarios with the logging module of NS-3 enabled (note that
-    this will work only when NS-3 is compiled in debug mode):
-
-    .. code-block:: bash
-
-        NS_LOG=ndn.Producer:ndn.Consumer ./waf --run=<scenario name>
-
-    If you have compiled with python bindings, then you can try to run these simulations with
-    visualizer:
-
-    .. code-block:: bash
-
-        ./waf --run=ndn-simple --vis
-
-    or:
-
-    .. code-block:: bash
-
-        ./waf --run=ndn-grid --vis
-
-    .. note::
-       Do not forget to configure and compile NS-3 in optimized mode (``./waf configure -d
-       optimized``) in order to run actual simulations.
+  When NS-3 is configured with ``--with-examples`` flag, you can directly run all examples
+  described in :doc:`examples section of this tutorial <examples>`.  For example, to run
+  ``ndn-simple.cpp`` scenario, you can run the following command:
+  
+  .. code-block:: bash
+  
+      ./waf --run=ndn-simple
+

+

+     Do not forget to configure and compile NS-3 in optimized mode (``./waf configure -d
+     optimized``) in order to run actual simulations.
 
 - Real experimentation
 
-    While it is possible to write simulations directly inside NS-3 (in ``scratch/`` folder) or
-    ndnSIM (in ``examples/``), the recommended way is to write your simulation scenarios, as
-    well as any custom extensions, separately from the NS-3 or ndnSIM core.
+  Simulation scenarios can be written directly inside NS-3 in ``scratch/`` or ``src/ndnSIM/examples`` folder.
+  
+  Alternative and a recommended way is to write simulation scenarios in a separate
+  repository, not related to either NS-3 or ndnSIM.  For example, you can use the
+  following template to write your extensions, simulation scenarios, and metric processing
+  scripts: `<http://github.com/cawka/ndnSIM-scenario-template>`_:
+  
+  .. code-block:: bash
+  
+      mkdir ndnSIM
+      cd ndnSIM
+      git clone https://github.com/named-data-ndnSIM/ns-3-dev.git ns-3
+      git clone https://github.com/named-data-ndnSIM/pybindgen.git pybindgen
+      git clone --recursive https://github.com/named-data-ndnSIM/ndnSIM.git ns-3/src/ndnSIM
+  
+      # Build and install NS-3 and ndnSIM
+      cd ns-3
+      ./waf configure -d optimized
+      ./waf
+  
+      sudo ./waf install
+      cd ..
+  
+      git clone https://github.com/named-data-ndnSIM/scenario-template.git scenario
