## Configuration

Swagger is configured with default settings. You can customize Swagger's default settings for all of your files thru a JSON object in your `config.toml` or override these settings per page thru your pages frontmatter.

The JSON object of your `config.toml` / frontmatter is forwarded into Swagger's initialization. At the moment, only the `theme` setting is supported.

The `theme` setting can also be set by your used color variant. This will be the sitewide default and can - again - be overridden by your settings in `config.toml` or frontmatter.

### Example

````toml
[params]
  swaggerInitialize = "{ \"theme\": \"dark\" }"
````

## Usage

Just insert your Mermaid code in the `mermaid` shortcode like this:

````go
{{</* swagger src="https://petstore3.swagger.io/api/v3/openapi.json" */>}}
````

The `src` parameter is mandatory and can be either an absolute URL or a relative one pointing into your Hugo file system.

## Example

{{< swagger src="https://petstore3.swagger.io/api/v3/openapi.json" >}}
