### Create metadata for tags { #create-metadata-for-tags }

Let's try that in an example with tags for `users` and `items`.

Create metadata for your tags and pass it to the `openapi_tags` parameter:

{* ../../docs_src/metadata/tutorial004.py hl[3:16,18] *}

### Crear metadata para etiquetas

Probemos eso en un ejemplo con etiquetas para `users` y `items`.

Crea metadata para tus etiquetas y pásala al parámetro `openapi_tags`:
