I have added a paragraph from wikipedia in my thesis. Now I need to add reference to that wikipedia page. What is the IEEE formatting and citation style for that? Currently I use as below.
In chapter of thesis added copied content from wikipedia as below

Since no formal software development methodologies existed at the time, this hardware-oriented model was simply adapted for software development .
