How do I add money to XMR?

Could you please elaborate on the process of adding funds to XMR? I'm interested in understanding the steps involved in funding my XMR wallet. Could you guide me through the necessary procedures, including any specific requirements or considerations I should be aware of? Additionally, are there any fees associated with depositing money into XMR, and if so, how are they calculated? I appreciate your assistance in clarifying this process for me.
