Download and install the package from the python package index (pypi):
easy_install django-markup
or if you prefer pip:
pip install django-markup
The latest development version is available from GitHub. You have to install git and checkout the package with:
git clone git://github.com/bartTC/django-markup.git
then install it manually:
cd django-markup
python setup.py install
Note that the development version is not fully tested and may contain bugs, so I prefer to use the latest package from pypi.
