The stable releases are uploaded to PyPI, so you can install and upgrade using pip:

pip install omni

Alternatively, you can install development versions —at your own risk— directly from the Git repository:

pip install -e git://github.com/aperezdc/omni

The documetation for OMNI is available at:

http://omni.readthedocs.org/en/latest/

If you want to contribute to OMNI, please use the usual GitHub workflow:

1. Clone the repository.
2. Hack on your clone of OMNI.
3. Send a pull request for review.

If you do not have programming skills, you can still contribute by reporting issues that you may encounter.
