What is Wikipedia?
Wikipedia is an encyclopedia that is written by many of its readers. It is a special type of website called a wiki, that makes working together easy. Many people are always improving Wikipedia, making many changes every day, all of which are recorded on article histories and recent changes. Changes which do not help the encyclopedia are usually removed quickly, and people who keep making bad changes can be blocked from changing.
How can I help?Don't be afraid to change — anyone can change almost any page, and we encourage you to be bold! Find something that can be improved and make it better. Maybe you know something about a subject that is not in the article, maybe you want to fix a spelling mistake. Go ahead and make that change!
You can't break Wikipedia. Anything can be fixed or improved later. So click "change this page" and help make Wikipedia the best information source on the Internet!
