## Installation

### How to obtain Avogadro

Avogadro can be found on the Avogadro home page.

### Requirements

Although Avogadro can work without any 3D-acceleration, an OpenGL capable card will vastly improve the user experience. At a minimum Avogadro requires a system capable of providing OpenGL software rendering. It is currently ported and tested on GNU/Linux, Apple Mac OS X and Microsoft Windows.

### Building Avogadro from source

If you decide to build Avogadro from source, the following resources will be necessary:

- Git, to access certain code repositories

- CMake (>=2.6.0), the open-source build system

- Qt4 (>=4.4.0), the open-source application framework

- Eigen2, a library for linear algebra as a compile-time dependency of Avogadro

- OpenBabel (>=2.2.0), the chemistry toolbox

All of these programs and libraries are likely to be available through your distribution's repository.

Further information can be found on the Avogadro home page.
