+description: "Guía de uso de Mermaid en Blowfish"
+summary: "Es fácil agregar diagramas y diagramas de flujo a los artículos usando Mermaid."
+tags: ["mermaid", "ejemplo", "diagrama", "shortcodes"]
+type: 'sample'
+---
+
+Los diagramas Mermaid son compatibles en Blowfish usando el shortcode `mermaid`. Simplemente envuelve el markup del diagrama dentro del shortcode. Blowfish adapta automáticamente los temas de los diagramas Mermaid al parámetro `colorScheme` configurado.
+
+Consulta la documentación del [shortcode mermaid]({{< ref "docs/shortcodes#mermaid" >}}) para más detalles.
+
+Los ejemplos siguientes son una pequeña selección tomada de la [documentación oficial de Mermaid](https://mermaid-js.github.io/mermaid/). También puedes [ver el código fuente de la página](https://raw.githubusercontent.com/nunocoracao/blowfish/main/exampleSite/content/samples/diagrams-flowcharts/index.md) en GitHub.
