-### Nested Tags
-
-Paperless-ngx v2.19 introduces support for nested tags, allowing you to create a
-hierarchy of tags, which may be useful for organizing your documents. Tags can
-have a 'parent' tag, creating a tree-like structure, to a maximum depth of 5. When
-a tag is added to a document, all of its parent tags are also added automatically
-and similarly, when a tag is removed from a document, all of its child tags are
-also removed. Additionally, assigning a parent to an existing tag will automatically
-update all documents that have this tag assigned, adding the parent tag as well.
