Welcome to Wikipedia!You have probably already edited blogs or social media sites. You have made edits that improved existing articles and now you want to start a new article from scratch. Now, if you have not done any Wikipedia editing, you cannot directly make a new article in mainspace. This permission is only for autoconfirmed users, which means those whose accounts are more than four days old and who have done at least ten edits. Non-confirmed users and non-registered users can submit a proposed article through the Articles for Creation process, where it will eventually be reviewed and considered for publication.
First, please be aware that Wikipedia is an encyclopedia, and our mission is to share accepted knowledge to benefit people who want to learn. We are not social media or a place to promote a company or product or person, or a place to advocate for or against anyone or anything. Please keep this in mind, always. (This is described in our "mission statement", "What Wikipedia is not".)
We find "accepted knowledge" in high quality, published sources. By "high quality" we mean books by reputable publishers, respected newspapers, or literature reviews in the scientific literature. We summarize such sources in Wikipedia articles. That is all we do! Please make sure that anything you write in Wikipedia is based on such sources - not what is in your head.
Here are some tips that can help you with your first article:
Register an account. All you need is to choose a username and password. This will give you various powers. After a few days of editing articles, it will give you the power to create a new one.
Search Wikipedia first in case an article already exists on the subject, perhaps under a different title. If the article already exists, feel free to make any constructive edits to improve it.
Nothing? OK, now you need to try to determine if the subject you want to write about is what we call "notable" in Wikipedia. The question we ask is - does this topic belong in an encyclopedia?
More than 200 articles are deleted from the English Wikipedia every day, mostly because of lack of notability. Please make sure your topic is notable by our definition before you spend time and effort on it. An article on a non-notable subject will be rejected or deleted. No amount of editing can overcome a lack of notability.
We generally judge this by asking if there are at least three high-quality sources that a) have substantial discussion of the subject (not just a mention) and b) are written and published independently of the subject (so, a company's website or press releases are not OK). Everything here is based on high-quality independent sources, and without them, we generally just cannot write an article. By far, the largest cause of frustration for a writer of a new article is caused by lack of notability. Anything else can be corrected by improving an article, but lack of notability means the article will not remain on Wikipedia, regardless of how well written it is. To avoid frustration, start by determining notability before you spend any effort on an article. If you are not sure if the subject you want to write about is "notable", you can ask questions at the Wikipedia Teahouse.
Please be mindful of conflict of interest. If you have one, you will probably have a hard time writing a good enough Wikipedia article (this is not about you, it is just human nature). However, if you insist on trying, you need to disclose your conflict of interest, and you need to try very hard not to allow your "external interest" to drive you to abuse Wikipedia. And you need to try hard to hear the feedback from independent people who review the draft before it is published and made available in the main encyclopedia. Your conflict of interest might lead you to believe something is "notable" when it isn't and to argue too hard for it to be published there.
Practice first. Before starting, try editing existing articles to get a feel for writing and for using Wikipedia's mark-up language—we recommend that you first take a tour through the Wikipedia tutorial or review contributing to Wikipedia to learn editing basics.
The Article Wizard will help you create your article in Draft space, and will put some useful templates into your draft, including the button to click when you are ready to submit the draft for review.
