The Wikimedia Foundation is a non-profit with a bold vision: Provide free and open knowledge to everyone around the world. We strive for balance and neutrality on our sites and for us, the best way to achieve our mission is to operate without ads or paywalls. For this reason, the Wikimedia Foundation is funded by donations. Your donations keep Wikipedia freely available and accessible to all.
