Just a simple example I googled:

• Sit in a quiet, comfortable place.
• Set a short time limit if you’re a beginner (e.g., 5–10 minutes).
• Focus on your breath and notice bodily sensations.
• Gently return your focus to your breath when distractions occur.

With body sensations, you can focus on the taste in your mouth for a minute, then switch to sounds you hear, how your fingertips feel etc. I usually close my eyes to better focus on each sensation. Just relax and gently observe what you experience right now.
