If you find adding citation/references https://en.wikipedia.org/wiki/Wikipedia:Citing_sources a very difficult thing as looking at the markup / lot of mouse clicks? Then you will love ProveIt :)
ProveIt http://proveit.wmflabs.org/ makes this easier and simple. It's easy to install http://proveit.wmflabs.org/install#en *no downloads needed*!
