How do I purchase XLM?

Excuse me, could you please elaborate on the process of purchasing XLM? I'm a bit new to the cryptocurrency world and am trying to understand the steps involved. Do I need to set up a specific wallet for XLM? What exchanges offer XLM trading, and how do I choose the right one? Also, are there any fees or limitations I should be aware of? I'd appreciate it if you could guide me through this process step by step.
