How do I send someone XMR?

Hello there, I'm interested in understanding how to send XMR, or Monero, to someone. Could you please walk me through the process step-by-step? I'm new to this and would appreciate any guidance you can offer. Specifically, I'm wondering about setting up a Monero wallet, generating a receiving address, and finally, initiating the transfer. Additionally, I'm curious about any security measures I should take to ensure the safety of my transaction. Thank you in advance for your help!
