Welcome to the community and thanks for your post in the forum!
I woudl recommend using the descriptions field which appear at the top of the folder once you view a folder and its content. Take a look at the screenshot as an example! In the new web experience, you will see the details tab and the option to post the description on the top. Place your instructions there and it will be viewable above the top items.
