how to use shortcuts app for beginners

I downloaded the shortcut to see what it does. Here is the comments it includes:

This shortcut helps someone with short term memory loss log what happens throughout the day, to help them keep track of what they have done, who they have met, etc.

It will ask you what you want to remember. If run for the first time for the day, it will create a new note and log the input, with the time. It it’s been run already, it will grab the note and append the the note with the time and new content.

There is an option to capture a photo and add to the note to create a visual diary.

Run this shortcut using Siri or save as a widget on the home screen.

Add multiple Personal Automations to run this shortcut periodically through the day to remind the user to capture events.

Use Personal Automation, to show each day’s note just before bedtime as a summary of what happened that day.

Running the shortcut creates entries in the Notes application. This is where you will find them. Their titles will begin with “What happened today”.
