+Installing boost libraries
+==========================
+
+Normally, to compile and install boost libraries in non-privileged mode, you would need to issue following commands (e.g., for boost version 1.51.0)::
+
+    export BOOSTDIR=/home/non-privileged-user/boost    
+
+    wget http://downloads.sourceforge.net/project/boost/boost/1.51.0/boost_1_51_0.tar.bz2
+    tar jxf boost_1_51_0.tar.bz2
+    cd boost_1_51_0
+    ./bootstrap.sh
+    ./b2 --prefix=$BOOSTDIR install
+
+However, after the following steps you may still not able to use ndnSIM.
+
+Common pitfalls
+---------------
+
+The common pitfalls is with boost iostreams library, which is failed to build because of missing bzip2 library.
+This problem can be easily fixed by downloading and installing bzip2 library, e.g., using the following steps::
+
+    wget http://www.bzip.org/1.0.6/bzip2-1.0.6.tar.gz
+    tar zxf bzip2-1.0.6.tar.gz
+    cd bzip2-1.0.6
+    make PREFIX=$BOOSTDIR CFLAGS="-fPIC -O2 -g" install
+
+Afte bzip2 library is installed, you may recompile and reinstall boost libraries using custom compilation flags::
+
+    ./b2 --prefix=$BOOSTDIR cxxflags=-I$BOOSTDIR/include linkflags=-L$BOOSTDIR/lib install
+
+Alternatively, you can solve this particular problem by installing development package for bzip2 library (if you have root access).  For example, on Ubuntu 12.04 it would be the following command::
+
+    sudo apt-get install libbz2-dev
+
+And then compiling and installing boost without custom compilation flags::
+
+    ./b2 --prefix=$BOOSTDIR
+
+
+Compiling NS-3 with custom boost libraries
+==========================================
+
+The following commands should allow compilation and run of NS-3 simulations with custom install of boost libraries::
+
+    cd <ns-3>
+    ./waf configure --boost-includes=$BOOSTDIR/include --boost-libs=$BOOSTDIR/lib --enable-examples --enable-ndn-plugins=topology,mobility
+    LD_LIBRARY_PATH=$BOOSTDIR/lib NS_LOG=ndn.Face:ndn.Consumer ./waf --run=ndn-simple
+
+.. note::
+    `LD_LIBRARY_PATH=$BOOSTDIR/lib` is necessary on Linux platform in order for the dynamic linker to find libraries installed in a location different from one of the folders specified in /etc/ld.so.conf.
