In one sentence, describe what the following article is about:

When citing Wikipedia in APA style, first list the name of the article. You do not need to use quotes or italics. Simply write down the article's title followed by a period. For example, if you were citing an article on Jimmy Carter the beginning your citation would look like this: Jimmy Carter. If you want to lead with an author's name, Wikipedia suggests using "Wikipedia contributors" as the name. In APA style, it's customary to include the date an online source was published or last modified. The date of the last revision is at the bottom of the Wikipedia page; if you cannot find the date, you can simply write "n.d." in parenthesis after the entry title. After the date, add a period. Returning to our example, your citation would look like this: Jimmy Carter. (n.d.). In APA style, it's customary to mention where you found an electronic source. When citing Wikipedia, you would write "In Wikipedia," italicizing the word "Wikipedia", and then add a period. Our citation should read as follows: Jimmy Carter. (n.d.). In Wikipedia. This is the date on which you accessed the information. Use the word "Retrieved" and then write the date. In APA style, the date is written "Month Date, Year." For example, if you retrieved your source on the 15th of October in 2015, you would write, "October 15, 2015." Add a comma after the date. To illustrate, here is what our example would look like so far: Jimmy Carter. (n.d.). In Wikipedia. Retrieved October 15, 2015, After the comma at the end of the date, write "from" and then include the full URL of the Wikipedia page. In our example, our final citation would read as follows:  Jimmy Carter. (n.d.). In Wikipedia. Retrieved October 15, 2015, from https://en.wikipedia.org/w/index.php?title=Jimmy_Carter&oldid=862298349  Remember to use the permalink, or other readers will have a hard time finding where you got your content from.

Summary:
Start your entry with the Wikipedia entry title. Include the date, if available. Write the words "In Wikipedia". Follow with the retrieval date. End with the URL.
