# 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
<!DOCTYPE html>
< html >
< head >
< title > Redoc< / title >
<!-- needed for adaptive design -->
2021-11-24 17:47:24 +03:00
< meta charset = "utf-8" / >
< meta name = "viewport" content = "width=device-width, initial-scale=1" / >
< link
href="https://fonts.googleapis.com/css?family=Montserrat:300,400,700|Roboto:300,400,700"
rel="stylesheet"
/>

:::attention Redoc requires an HTTP server to run locally
2021-11-23 08:07:56 +03:00
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
2022-02-09 15:18:16 +03:00
other security reasons. Refer to [Running Redoc locally ](./deployment/intro.md#how-to-run-redoc-locally ) for more information.
