This multilingual web based free content encyclopedia already contains millions of articles but there is always room for more. Why not publish something by you? This is an article on how to create a Wikipedia article.
Before you try to create an article make sure you have an appropriate topic. Wikipedia wants un-biased and well sourced information about subjects that are notable enough to appear in an encyclopedia. The site rejects articles that promote or publicize a business, advice legal or otherwise, instructional material, travel guides, and news items.
Make sure you get the information for your article from creditable and reliable sources. Material from books or newspapers is generally considered reliable. Pulling your info from bloggers is not.
Make sure Wikipedia hasn’t already published an article on your exact subject. You can do this by typing your subject into the sites internal search box.
Search the topic on Google to see if it finds any Wikipedia articles on your subject. Google sometimes picks up listings that Wikipedia’s own search engine misses.
Become a registered user to submit an article without first gaining the sites approval. Having an account also means you can create a user profile, receive messages from other users, request notification when changes are made to articles, and get credit for the articles you write. Click on create an account on the top right of any page.
Practice writing an article by composing a draft in the sandbox, where you can familiarize yourself with the sites editing tools. Get there by typing WP:SB in the search box and press go. Click Help in the tool box of any page for guidance.
Type your subject in the search box and hit Go. You already determined that no page with that title exists, click on your highlighted search entry you will be redirected to a blank page where you can begin writing your article.
When your article is finished click show preview to proof read your work and see how it will appear on the site, when you are ready to publish click save page.
