:*[[WP:NPOV|Neutral point of view]]: Wikipedia strives to keep the tone of its articles neutral. Both favorable and unfavorable information may be included, but advertising is not permitted and neither are attacks. If you can quote the opinions of relevant authoritative sources, please do so, but including your personal opinion on an article's subject is not allowed and such additions will be removed.
:To put it another way, articles should be written in natural, but neutral, language and merely summarize factual information from third-party articles, studies, reports and books that are already in print. This is in contrast to what many people with a conflict of interest do, which is to write in a promotional tone summarizing their own highly favorable personal knowledge and opinions of the topic. If you can write articles just by summarizing sources in a neutral tone, it is much less likely that you will run into any kind of problems with other editors.
