How do you become a validator on Aleph zero?

Could you elaborate on the process involved in becoming a validator on Aleph Zero? I'm curious about the technical requirements, the initial set-up process, and any specific steps that need to be followed to ensure secure and reliable validation. Additionally, I'd like to know if there are any specific hardware or software requirements that must be met, as well as any potential risks or considerations that validators should be aware of. I'm interested in understanding the entire process from start to finish, including any ongoing responsibilities and requirements for maintaining a validator node on the Aleph Zero network.
