How do I make my CR-V automatically start?

Could you please explain to me, in a step-by-step manner, how I can program my Honda CR-V to automatically start? I'm interested in this feature for convenience purposes, especially during colder weather. Would I need to use a special remote or does the car already have the necessary technology? Additionally, are there any safety considerations I should be aware of when utilizing this function? Thank you for your assistance in clarifying this matter.
