I am going to show you a technique to put "notes" on your ServiceNow forms. When used in combination with Knowledge Base articles, these notes can make ServiceNow even more user-friendly.
ServiceNow has functionality called Form Annotations that is helpful in separating data beyond sections in your forms:

There are a couple different form annotation types OOB that you can use:
Info Box Blue
Info Box Red
Line Separator
Section Separator
Text
As an example to see which each one looks like, I added them all to a form. Below I add the different form annotations to one form.

Here are all the different types in action
For my idea of a notes field, I like to the "Section Separator" Form annotation and an Info Box Blue Form annotation.
Adding a "notes" Form Annotation Example
In ServiceNow, View the form you want to add a notes field
Right click the header bar and click Personalize > Form Layout
Click Save
Also note that you can make your own form annotation types. Maybe you prefer a different color scheme or have a unique idea for layout? Form Annotation types use common styles that you can modify. Something to consider when you have a brief note to mention to users.
