How do I start mining bitcoin on my Raspberry Pi?

Could you elaborate on the process of initiating Bitcoin mining using a Raspberry Pi? I'm curious about the necessary steps to set up the hardware and software, as well as the potential challenges and limitations I may encounter. I'm also interested in understanding the profitability of such a setup, given the current market conditions and the relatively limited computing power of a Raspberry Pi. Would it be feasible to mine Bitcoin effectively on such a device, or would it be more practical to explore alternative cryptocurrencies? Any advice or recommendations would be greatly appreciated.
