How do I buy Algorand?

Excuse me, I'm quite new to the cryptocurrency world and I'm interested in purchasing Algorand. Could you possibly guide me through the process? I'm wondering where exactly I should go to make the purchase, what steps I need to follow, and if there are any specific requirements or prerequisites? Additionally, is there a recommended platform or exchange that you would suggest for buying Algorand? And what about fees and security measures? Could you elaborate on those as well? I appreciate your help in this matter.
