[Qgis-user] How to reference a map

[Kelly V]

Hi,

I've used QGIS 2.4.0-Chugiak to create maps for my assignment.
I would like to know what is the correct way to reference QGIS in-text and in the bibliography.

I've looked it up a bit and I found that I'm supposed to use this:

QGIS Development Team (YEAR). QGIS Geographic Information System. Open Source Geospatial Foundation Project. http://qgis.osgeo.org

I've no idea what year I'm supposed to put in the parenthesis for the version I used and the link doesn't work for me. could someone please tell me in a clear way how I'm supposed to do it?
