As a general rule, NEVER COPY-PASTE TEXT FROM OTHER WEBSITES
. (There are a few limited exceptions, and adding a few words as part of a properly cited and clearly attributed quotation is OK.)
Your article submission must not violate copyright.
Do not copy and paste text, unless it is a properly attributed and sourced quotation. Articles violating copyright will be deleted. Write the article yourself in your own words. It's okay if your text is not perfect — that can always be fixed later. (Similarly, if you're considering uploading an image for the article and you've not done so before, you might want to wait a few days to get input from others on your article.)
Your article should also establish notability.
On a previous page, you were given guidelines on what makes your subject notable enough to merit inclusion in Wikipedia. Be sure that by the time the reader finishes reading your article, they will understand why the subject is notable.
Your article must be neutral in its tone.
Articles in Wikipedia strive to adhere to a neutral point of view, meaning that it neither is "for" nor "against" any particular subject matter. While properly cited praise or criticism of the subject is perfectly acceptable, your article should approach it from a neutral tone. Just write about facts — it is fine to include the fact that somebody else has published an opinion, but do not write about your own. Articles must represent all significant views fairly, proportionately, and without bias. Articles that only attack their subject may be deleted, and articles that serve only to praise a subject may be deleted or radically edited by others seeking a neutral tone.
Your article should not engage in puffery.
Puffery is when an article attempts to exaggerate the notability of its subject. Puffery only serves to reduce the neutrality of the article and so it should be avoided. The most common type of puffery is the use of peacock terms.
