Add relevant information
Admonitions can be distracting. Consider how they help users before adding them.

Highlight something important
Users read admonitions before content. They can communicate essential information.
{% admonition type="warning" name="Read this!" %} Users read admonitions _before_ content. They can communicate essential information. {% /admonition %}

Best practices
Use in moderation Overuse of admonitions will reduce their effectiveness and users will learn to ignore them.
Don't use for page content Carefully consider the information you put in your admonitions. They should add value and clarity or communicate something important. If readers don't know what to expect, then admonitions won't draw their attention effectively.
Use clear headers Use short, impactful headers that reflect the content to set the tone and encourage users to pay attention to the message.
Choose the right type Select the admonition type that aligns with the nature of the content. This helps users understand intent and recognize the level of urgency. For example, you should use warning for cautionary information and success for confirmation or positive feedback.
Admonitions after content Avoid using admonitions as the first element below headers or section headers. Giving readers information to consider before content adds to their cognitive load and reduces comprehension.
