# Breadcrumb The breadcrumb is a secondary navigation pattern that helps a user understand the structure between levels in the website up to the current page. Users can use it to navigate. ## Guidelines - Only use the breadcrumb trail if it adds something functional for the user and the structure is ‘static’. - Do not display the breadcrumb trail on a form page. It distracts the user from their task, or one can accidentally interpret it as a Progress Indicator. - This is a secondary navigation pattern. It can’t replace the main navigation. ### Using links with routing libraries Check out the [developer guide](/docs/docs-developer-guide-routing-libraries--docs) on how to integrate links with external routing libraries.
