How do you start a bike step by step?

Excuse me, could you please elaborate on the process of starting a bike, step by step? I'm interested in understanding the entire sequence, from preparing the bike to actually getting it moving. Are there any specific checks or adjustments I should make before attempting to ride? Additionally, are there any safety precautions I should keep in mind while starting and riding the bike? I'd appreciate a detailed, step-by-step guide to ensure a smooth and SAFE experience.
