How do I buy on OKX?

I'm curious about the process of buying cryptocurrency on OKX. Could you please guide me through the steps? I'm new to this platform and would appreciate a clear and concise explanation of how to navigate the buying process. From creating an account to depositing funds and finally placing an order, I'd like to understand the entire flow. Additionally, are there any specific fees or limitations I should be aware of before making my first purchase? Your help would be greatly appreciated.
