How do you buy Stacks?

Can you walk me through the process of purchasing Stacks? I'm new to the world of cryptocurrency and I'm curious about the steps involved in acquiring this particular digital asset. Do I need to set up a cryptocurrency wallet first? And once I have one, what's the best way to go about buying Stacks? Are there any specific exchanges or platforms that you recommend for making this purchase? Additionally, are there any fees or other costs associated with buying Stacks that I should be aware of? Your guidance would be greatly appreciated.
