How do I buy coins on Indodax?

Could you please guide me through the process of purchasing coins on Indodax? I'm a bit new to this platform and would appreciate a step-by-step approach. Firstly, do I need to register an account and verify my identity? After that, how do I fund my account with Indonesian Rupiah or other supported currencies? And finally, what are the specific steps involved in selecting a coin, placing an order, and confirming the purchase? Thank you in advance for your help.
