How do you unstake MSOL?

Could you please elaborate on the process of unstaking MSOL? I understand staking as a means to earn rewards by locking up coins for a period of time, but I'm curious about the steps required to reverse this process. Do I need to wait for a specific unstaking period to elapse? Are there any fees associated with unstaking MSOL? And once unstaked, can I immediately transfer or trade my MSOL tokens, or are there additional steps I need to take? Thank you for your guidance in navigating this process.
