How do I add an on/off button to a Raspberry Pi Zero board? I am new to the platform and kindly ask for instructions suitable for a novice. Thank you.

1Why? What is the objective? Do none of the hundred similar questions not provide an answer?– MilliwaysCommented Apr 4, 2019 at 3:41

Please clarify: Do you want a button to shut the pi down/turn it back on or a button to disconnect power/reconnect power?– Benjamin AshbaughCommented Apr 4, 2019 at 4:13

You can follow this guide on adding a Power Button to your Raspberry Pi. It shows how to do it on an RPi 3 model, but you can do exactly the same on the RPi Zero, as their pinout is the same.
The only caveat with your RPi model is the soldering. Here is a video from the Raspberry Pi Foundation on how to solder pins to your RPi Zero. And here is another guide on how to add 40-pin GPIO connector.
Edit
If the guide to add a power button is down, here is a copy of it on Wayback Machine.
Adding an on/off is fairly simple IF you can solder pretty good. However, depending on where the Pi is located, you could get on of the usb cables that come with a on/off switch. They are fairly cheap and come in various links. I have a couple that I use EVEN though I poweroff the pi.

1A power switch on the USB cable is no good if the OP wants the pi to shut down when the button is pressed. Commented Apr 4, 2019 at 4:12

@scitronbon, GREAT point. I did not grasp his initial point, I was only thinking of just removing the power after using shutdown command. I think that David's post answers his question.– voyager8Commented Apr 4, 2019 at 12:31
