How to buy MakerDAO?

Could you kindly explain the process of purchasing MakerDAO, step by step? I'm quite new to the cryptocurrency world and would appreciate a clear, concise guide. Do I need to set up a specific wallet or exchange account? Are there any fees involved? And how do I ensure the safety of my transaction? I'm eager to get started but want to make sure I'm doing it correctly and securely. Thank you for your assistance.
