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 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.
Does your article submission meet the content requirements?
↑ अआThere are a very few websites (and other sources) from which text can be copy-pasted without violating copyright — cases where the text is in the public domain or uses a Wikipedia-compatible license (for the latter, attribution is usually required. Even content copied from other Wikipedia articles needs attribution, per Wikipedia:Copying within Wikipedia). If you think your source may qualify, please ask for confirmation at Wikipedia talk:Copyright problems, and await a response before finishing this wizard.
↑Relevant, illustrative images are great, but if you didn't create the image yourself, the copyright issues can be a minefield. If you have a specific previously-published image in mind, you can ask a question at Wikipedia:Media copyright questions; you could also look for a suitable existing image either on Wikipedia or on Wikimedia Commons. (You can use images from the Commons in the same way as local Wikipedia ones.)
