How do I add Aurora?

Could you please elaborate on the process of adding Aurora to my cryptocurrency portfolio? I'm a newcomer to this space and would appreciate a step-by-step guide. Specifically, I'm interested in understanding how to locate Aurora on an exchange, what factors I should consider before making a purchase, and any potential risks or challenges I might encounter along the way. Additionally, if there are any recommended wallets or storage solutions for Aurora, I'd love to hear about those as well. Thank you for your assistance in navigating this new territory.
