Hi Jim,

I haven't installed datastorer before myself, but I would try reading
the 'Installing an Extension' docs here:

http://docs.ckan.org/en/ckan-1.7/extensions.html#installing-an-extension

and then you might understand the ckanext-datastorer README a little
better. For example, I would probably download ckanext-datastorer by
activating my virtualenv and running a command like:

    pip install -e git+https://github.com/okfn/ckanext-datastorer.git#egg=ckanext-datastorer

this should download and install ckanext-datastorer in a directory like:

    pyenv/src/ckanext-datastorer

You might still need to run pip install -r on the requires.txt file in
the ckanext-datastorer directory.

In the plugins line of your CKAN ini file you should add something like:

    plugins = datastorer

A couple of things you can do to test whether datastorer is working
properly are to run CKAN with `paster serve development.ini` and see if
it crashes with something like 'Plugin not found: datastorer', run the
datastorer tests, something like:

    nosetests tests

from the ckanext-datastorer directory, and to try out the
`paster datastorer` command (from the pyenv/src/ckan directory).
