-# Building from source
-
-First, Download the latest source code of moose from github.
-
-    $ git clone https://github.com/BhallaLab/moose
-    $ cd moose
-
-## Install dependencies
-
-For moose-core:
-
-- gsl-1.16 or higher.
-- libhdf5 
-- libsbml (optional)
-
-    Make sure that `libsml` is installed with `zlib` and `lxml` support.
-    If you are using buildtools, then use the following to install libsbml.
-
-        - wget http://sourceforge.net/projects/sbml/files/libsbml/5.9.0/stable/libSBML-5.9.0-core-src.tar.gz
-        - tar -xzvf libSBML-5.9.0-core-src.tar.gz 
-        - cd libsbml-5.9.0 
-        - ./configure --prefix=/usr --with-zlib --with-bzip2 --with-libxml 
-        - make 
-        - ctest --output-on-failure # optional
-        - sudo make install 
-
-For python module of MOOSE, following additional packages are required:
-
-- Development package of python e.g. libpython-dev 
-- python-numpy 
-
-For python-gui, we need some more addtional packages
-    
-- matplotlib
-- setuptools  (cmake uses it to install moose python extension and moogli)
-- suds 
-- Python bindings for Qt4 or higher
-- Python OpenGL
-- Python bindings for Qt's OpenGL module
-
-On Ubuntu-120.4 or higher, these can be installed with:
-    
-    sudo apt-get install python-matplotlib python-qt4 python-qt4-gl 
-
-## Use `cmake` to build moose:
-
-    $ mkdir _build
-    $ cd _build 
-    $ cmake -DWITH_DOC=OFF ..
-    $ make 
-    $ ctest --output-on-failure
-
-This will build moose and its python extentions, `ctest` will run few tests to
-check if build process was successful.
-
-To install MOOSE into non-standard directory, pass additional argument
-`-DCMAKE_INSTALL_PREFIX=path/to/install/dir` to cmake.
-
-After that installation is pretty easy.
-
-## Install
-
-    $ sudo make install
-
-# Building and installing moogli 
-
-MOOGLI is subproject of moogli for visualizing models. Details can be found
-[here](http://moose.ncbs.res.in/moogli).
-
-MOOGLI dependencies are huge! It uses `OpenSceneGraph` which has its own
-dependencies. In nutshell, depending on your distribution, you would need
-following packages to be installed.
-
-- Development package of libopenscenegraph 
-- [libQGLViewer-2.3.15-py](https://gforge.inria.fr/frs/?group_id=773). Install
-instructions [here](http://www.libqglviewer.com//installUnix.html#linux)
-
-- [PyQGLViewer0.10](https://gforge.inria.fr/frs/?group_id=773) (first install
-libQGLViewer-2.3.15-py) and untar contents.
-
-    $ cd / PyQGLViewer0.10
-    $ python setup.py build # to compile
-    $ python setup.py install # to install on your system
-    $ python setup.py bdist # to create a binary distribution
-
-On Ubuntu, following packages should suffice:
-
-    $ sudo apt-get install python-qt4-dev python-qt4-gl libopenscenegraph-dev python-sip-dev
-    libqt4-dev 
-
-
-## Travis
-
-We use `Travis-CI` to build MOOSE after every commit. You can see `.travis.yml`
-file in our repository. It has all instructions to build MOOSE on `Ubuntu-12.04
-64bit` server.
