Use references. This is an encyclopedia, so remember to include references listing websites, newspapers, articles, books and other sources you have used to write or expand articles. New articles and statements added to existing articles may be deleted if unreferenced or referenced poorly. See: Wikipedia:Citing sources and Wikipedia:Verifiability for more information.
IV.
Keep it simple. Remember that the average reader should be able to comprehend the erudition. Although you should use a broad vocabulary of regular, non-technical terms, do not provide such a quantity of locutions as to impel those who aspire to derive serviceable information from the article to consult a dictionary or thesaurus. Stay on topic as many articles are criticized for length; sticking to the subject matter helps eliminate this. See: Wikipedia:Writing better articles and Wikipedia:The perfect article for more information..
V.
Use images if possible. Images enhance articles greatly, but only use them when they are necessary, and ensure that their copyright status has been specified and we are allowed to use it on Wikipedia. See: Wikipedia:Images and Wikipedia:Picture tutorial for more information.
