Making sure your assets are used correctly is important when sharing your library. Perhaps you don't want your logo shown in different colors or orientations, or you are putting together a copywriting guide.
Guides are an easy way to help explain how certain content should be used.
Options for guides include:
Do or Don't. This will also update the color to red or green respectively
Guides can be text only or shown with an image
The text can be formatted just like notes
