All you need is a single HTML file to create an amazing API reference:

```html

Scalar API Reference

Scalar.createApiReference('#app', {
// The URL of the OpenAPI/Swagger document
url: 'https://registry.scalar.com/@scalar/apis/galaxy?format=json',
// Avoid CORS issues
proxyUrl: 'https://proxy.scalar.com',
})

```
