+Installing GSL
+==============
+
+To install GSL in your home directory, you can run the following commands:
+
+    $ curl -O -L ftp://ftp.gnu.org/gnu/gsl/gsl-2.5.tar.gz
+    $ tar -xzvf gsl-2.5.tar.gz
+    $ cd gsl-2.5
+    $ mkdir $HOME/local
+    $ ./configure --prefix=$HOME/local
+    $ make
+    $ make install
+
+Installing NLopt
+================
+
+    $ curl -O -L https://github.com/stevengj/nlopt/archive/v2.5.0.tar.gz
+    $ tar -xzvf v2.5.0.tar.gz
+    $ cd nlopt-2.5.0
+    $ mkdir build
+    $ cd build
+    $ cmake -DCMAKE_INSTALL_PREFIX=$HOME/local ..
+    $ make
+    $ make install
+
+To use gsl and nlopt installed locally, you will have to edit the Makefile and
+add the following to the CFLAGS and LDLIBS variables:
+
+    CFLAGS=-I$(HOME)/local/include
+    LDLIBS=-L$(HOME)/local/lib -L$(HOME)/local/lib64
+
+and also edit the -lnopt_cxx line to just be -lnlopt.
+
+You will also need to edit ~/.bash_profile and add the following line:
+
+    export LD_LIBRARY_PATH=$HOME/local/lib:$HOME/local/lib64
