+Content editors and product managers can use [taxonomy suggestions](taxonomy.md#taxonomy-suggestions) when assigning tags or product categories to content items and products.
 Instead of manually browsing through extensive taxonomy trees, editors can request suggestions based on the content's text fields, such as name and description.
