Best practices
Let your app’s tasks inform the types of help people might need.
Use relevant and consistent language and images in your help content.
Make sure all help content is inclusive.
Avoid bloating your help content by explaining how standard components or patterns work.
Creating tips
Use the most appropriate tip type for your app’s user interface.
Use tips for simple features.
Make tips short, actionable, and engaging.
Define rules to help ensure your tips reach the intended audience.
If there’s an image or symbol that people associate with the feature, consider including it in the tip, and prefer the filled variant.
Use buttons to direct people to information or options.
Platform considerations

Describe only the control that people indicate interest in.

In general, avoid repeating a control’s name in its tooltip.
