How do I add money on CoinGecko?

Excuse me, I'm trying to figure out how to add money to my account on CoinGecko. Could you please walk me through the process? I'm a bit new to this cryptocurrency world and I'm not sure where to start. Are there any specific steps I need to follow, or any payment methods that are preferred? Additionally, is there a minimum amount I need to deposit, and are there any fees associated with the process? Your help would be greatly appreciated.
