Don't be afraid to edit – anyone can edit almost every page, and we are encouraged to be bold! Find something that can be improved and make it better—for example, spelling, grammar, rewriting for readability, adding content, or removing non-constructive edits. If you wish to add new facts, please try to provide references so they may be verified, or suggest them on the article's discussion page. Changes to controversial topics and Wikipedia's main pages should usually be discussed first.
Contributing to Wikipedia will provide you with resources on all the basics needed to use, comment on, and contribute to Wikipedia.
Remember – you can't break Wikipedia; all edits can be reversed, fixed or improved later. Wikipedia is allowed to be imperfect. So go ahead, edit an article and help make Wikipedia the best information source on the Internet!
