Where can I download Uniswap?

Could you please tell me where I might be able to locate and download Uniswap? I've heard it's a popular decentralized exchange for cryptocurrencies, but I'm not sure exactly where to start looking. Is there a specific website or platform that offers the Uniswap application for download? Also, are there any specific requirements or steps I need to follow in order to successfully install and use Uniswap? I'm quite new to this cryptocurrency world and would appreciate any guidance you can provide. Thank you in advance for your help!
