How do I trade on BitMart?

I'm curious about how to trade on BitMart. Can you provide a step-by-step guide on how to navigate the platform and execute trades? Are there any specific requirements or verifications I need to complete before I can start trading? Additionally, are there any fees associated with trading on BitMart, and if so, how do they compare to other exchanges? Lastly, is there a mobile app available for trading on the go, or is the platform solely accessible through a web browser? Thank you for your help in clarifying these questions.
