How do I claim Kusama?

So, I've been hearing a lot about Kusama and its potential in the world of blockchain and cryptocurrency. But I'm a bit confused about how exactly one can go about claiming Kusama. Could you please walk me through the process? Do I need to purchase it from an exchange? Are there any specific requirements or steps I need to follow? And what are the benefits of owning Kusama that I should be aware of? Your guidance would be greatly appreciated.
