• First, review our guideline on notability, our policy on Verifiability, and our general notability guideline (GNG). Consider whether your subject clearly meets the standards listed there. Also, check if the topic is already covered, perhaps under a different spelling or in a section of an article about a wider topic. You will waste a lot of time, if you create a new article, and then find that the encyclopedia already has an article about that.
• Second, read how to create Your First Article and referencing for beginners and again consider if you want to go ahead.
• Third, If you have any connection or affiliation with the subject, disclose it in accordance with our guideline on Conflict of interest. If you have been or expect to be paid for making edits, or are making them as part of your job, disclose this according to the strict rules of the Paid-contribution disclosure. This is absolutely required; omitting it can result in you being blocked from further editing.
• Fourth, gather sources. You want independent, professionally published, reliable sources with each discussing the subject in some detail. If you can't find several such sources, stop; an article will not be created! Sources do NOT need to be online, or in English, although it is helpful if at least some are. The "independent" part is vital. Wikipedia does not consider as independent sources such as press releases, or news stories based on press releases, or anything published by the subject itself or an affiliate of the subject. Strictly local coverage is also not preferred. Regional or national newspapers or magazines, books published by mainstream publishers (not self-published), or scholarly journals are usually good. So are online equivalents of these. (Additional sources may verify particular statements but not discuss the subject in detail. But those significant detailed sources are needed first.)
• Fifth, use the article wizard to create a draft under the articles for creation project. This is always a good idea for an inexperienced editor, but in the case of an editor with a conflict of interest it is essential.
• Sixth, use the sources gathered before (and other sources you may find along the way) to write the article. Cite all significant statements to sources. Do not express opinions or judgements, unless they are explicitly attributed to named people or entities, preferably in a direct quotation, and cited to a source. Do not use puffery or marketing-speak. Provide page numbers, dates, authors and titles for sources to the extent these are available. A title is always needed. Submit the draft when you think it is ready for review. Be prepared to wait a while for a review (several weeks or more).
• Seventh, when (well perhaps if) your draft is declined, pay attention to the comments of the reviewer, and correct the draft and resubmit it. During this whole process, if you face any unresolvable editing hurdles, or cannot comprehend any editing issue, feel free to post a request at the Teahouse or the help desk and ask the regulars. Repeat this until the draft passes review.

Congratulations, you have now created a valid Wikipedia article.
