You should write some docs, it's good for the soul.
Create a new virtualenv for horndata, install GeoNode and setup your project:
$ mkvirtualenv my_geonode $ pip install Django $ django-admin.py startproject my_geonode --template=https://github.com/GeoNode/geonode-project/archive/master.zip -epy,rst $ pip install -e my_geonode
To install the latest from GeoNode's master branch use the following command:
$ pip install -e git+https://github.com/GeoNode/geonode.git#egg=geonode --upgrade
Note
You should NOT use the name geonode for your project as it will conflict with the default geonode package name.
Setup your GeoNode for usage. Download a geoserver.war to use and start the development server:
$ cd my_geonode $ paver setup # downloads geoserver $ paver start
