Hi,

Your article seems to be very inspired from this link and the associated wikipedia entry. For a matter of honesty, and fairness, it is always important to add the references used to write an article. Some sentences are by the way taken as such from the two sources. In this case, it would be better, at least for the reader standpoint, to clearly indicate what you have taken identically to the sources and what is definitely yours (and thus original), using markdown style for instance.

Of course, all of this is my opinion and you are allowed to follow it or not! This is up to you :)
