How do I set up Aurora app?

Could you please elaborate on the steps involved in setting up the Aurora app? I'm new to cryptocurrency and would appreciate a step-by-step guide. Specifically, I'm wondering about the initial download process, creating a secure account, any necessary verification steps, and how to ensure the safety of my transactions within the app. Additionally, is there a recommended amount of cryptocurrency I should start with or any specific coins that are more suitable for beginners? Thank you for your assistance in navigating this process.
