# Redoc quickstart guide
To render your OpenAPI definition using Redoc, use the following HTML code sample and
replace the `spec-url` attribute with the URL or local file address to your definition.
```html
Redoc
```
:::attention Running Redoc locally requires an HTTP server
Loading local OpenAPI definitions is impossible without running a web server because of issues with
[same-origin policy](https://developer.mozilla.org/en-US/docs/Web/Security/Same-origin_policy) and
other security reasons. Refer to [Running Redoc locally](./deployment/intro.md#running-redoc-locally) for
more information.
:::
For a more detailed explanation with step-by-step instructions and additional options for using Redoc, refer to the [Redoc deployment guide](./deployment/intro.md).
