> **NOTE:** `{1...n}` shown have 3 dots! Using only 2 dots `{1..n}` will be interpreted by your shell and won't be passed to MinIO server, affecting the erasure coding order, which would impact performance and high availability. **Always use ellipses syntax `{1...n}` (3 dots!) for optimal erasure-code distribution**

### Pruébalo

Ahora, deberías poder ir a tu documentación en <a href="http://127.0.0.1:8000/docs" class="external-link" target="_blank">http://127.0.0.1:8000/docs</a>, y recargar la página, cargará esos recursos desde el nuevo CDN.

## Self-hosting de JavaScript y CSS para la documentación

### Disable the automatic docs { #disable-the-automatic-docs }

The first step is to disable the automatic docs, as by default, those use the default CDN.

To disable them, set their URLs to `None` when creating your `FastAPI` app:

{* ../../docs_src/custom_docs_ui/tutorial001.py hl[8] *}

### Include the custom docs { #include-the-custom-docs }

Now you can create the *path operations* for the custom docs.
