How do you buy on Spookyswap?

Excuse me, could you please explain the process of buying on Spookyswap? I'm a bit new to this and would appreciate a step-by-step guide. Is there a specific cryptocurrency I need to have in my wallet first? Also, do I need to connect my wallet to the platform? Are there any fees associated with buying on Spookyswap? And finally, is there a limit to how much I can buy at once? I'm eager to learn more and start using the platform. Thank you for your help.
