How do I send money to my Atomic Wallet?

I'm curious about how I can send money to my Atomic Wallet. Could you please walk me through the process step-by-step? I'd like to know if there are any specific requirements or precautions I should be aware of before making a transfer. Additionally, how long does it typically take for the funds to arrive in my wallet once I've initiated the transfer? Any information you can provide would be greatly appreciated.
