Installing Qbics
===================

Qbics is actaully **NOT** needed to be installed. We have provided compiled executables so no compilation is needed. Just download it from the official website:

.. centered::
     http://qbics.info

The Windows and Linux version is a .zip and .tar.gz compressed package, respectively. Just decompress them, and Qbics is ready for use!

After decompression, you may get the following files:

.. code-block:: bash

    qbics
    |------ basis    
    |------ pseudopotential
    |------ tools
    |------ qbics-win/linux-cpu

``qbics-win/linux-cpu`` is the qbics executable ready for use.

You can run qbics by using absolute path. On Windows:

.. code-block:: 

    $ D:\software\qbics\qbics-win-cpu water.inp > water.out

or on Linux:

.. code-block:: 

    $ /opt/qbics/qbics-linux-cpu water.inp > water.out

Of course, you can also put ``D:\software\qbics`` or ``/opt/qbics`` to ``PATH`` variable so you need not to type absolute path, but this is not mandated.
