How you can contribute
Don't be afraid to edit – Anyone can edit almost every page, just find something that can be improved and make it better! You can create new articles, or improve existing articles by adding content, references and images, or correcting spelling, grammar and readability. If you wish to add new facts, please try to provide reliable references so they may be verified. Remember, you can't break Wikipedia; all edits can be fixed or improved later. So go ahead, edit an article and help make Wikipedia the best information source on the Internet!
Suggest improvements – Each article also has a 'Talk page', where you can suggest improvements and corrections to the article.
Donate – Wikipedia is free to use, but relies on donations and grants to do so. Please consider donating using the Donate to Wikipedia link on the left to help with the project's running costs and expansion.
