How do I buy SCP?

Excuse me, could you please explain the process of purchasing SCP? I'm new to the world of cryptocurrency and I'm a bit lost. Do I need to set up a specific wallet or exchange account? Are there any specific steps I need to follow? I'm eager to get started but I want to make sure I do it correctly. Can you guide me through the entire process, from creating an account to making my first purchase? Thank you in advance for your help.
