You can assign a list of tags to each API operation. Tagged operations may be handled differently by tools and libraries. For example, Swagger UI uses tags to group the displayed operations.
Optionally, you can specify externalDocs for each tag by using the global tags section on the root level. The tag names here should match those used in operations.
The tag order in the global tags section also controls the default sorting in Swagger UI. Note that it is possible to use a tag in an operation even if it is not defined on the root level.
