---

[Mermaid](https://mermaidjs.github.io/) is a library helping you to generate diagram and flowcharts from text, in a similar manner as Markdown.

Just insert your mermaid code in the `mermaid` shortcode and that's it.

## Flowchart example

	{{</*mermaid align="left"*/>}}
	graph LR;
		A[Hard edge] -->|Link text| B(Round edge)
    	B --> C{Decision}
    	C -->|One| D[Result one]
    	C -->|Two| E[Result two]
    {{</* /mermaid */>}}

renders as

{{<mermaid align="left">}}
graph LR;
	A[Hard edge] -->|Link text| B(Round edge)
    B --> C{Decision}
    C -->|One| D[Result one]
    C -->|Two| E[Result two]
{{< /mermaid >}}

or you can use this alternative syntax:

<pre>
```mermaid
graph LR;
  A[Hard edge] -->|Link text| B(Round edge)
    B --> C{Decision}
    C -->|One| D[Result one]
    C -->|Two| E[Result two]
```
</pre>

renders as

```mermaid
graph LR;
  A[Hard edge] -->|Link text| B(Round edge)
    B --> C{Decision}
    C -->|One| D[Result one]
    C -->|Two| E[Result two]
```

## Sequence example

	{{</*mermaid*/>}}
	sequenceDiagram
	    participant Alice
	    participant Bob
	    Alice->>John: Hello John, how are you?
	    loop Healthcheck
	        John->John: Fight against hypochondria
	    end
	    Note right of John: Rational thoughts <br/>prevail...
	    John-->Alice: Great!
	    John->Bob: How about you?
	    Bob-->John: Jolly good!
	{{</* /mermaid */>}}

renders as

{{<mermaid>}}
sequenceDiagram
    participant Alice
    participant Bob
    Alice->>John: Hello John, how are you?
    loop Healthcheck
        John->John: Fight against hypochondria
    end
    Note right of John: Rational thoughts <br/>prevail...
    John-->Alice: Great!
    John->Bob: How about you?
    Bob-->John: Jolly good!
{{< /mermaid >}}

or you can use this alternative syntax:

<pre>
```mermaid
sequenceDiagram
    participant Alice
    participant Bob
    Alice->>John: Hello John, how are you?
    loop Healthcheck
        John->John: Fight against hypochondria
    end
    Note right of John: Rational thoughts <br/>prevail...
    John-->Alice: Great!
    John->Bob: How about you?
    Bob-->John: Jolly good!
```
</pre>

renders as

```mermaid
sequenceDiagram
    participant Alice
    participant Bob
    Alice->>John: Hello John, how are you?
    loop Healthcheck
        John->John: Fight against hypochondria
    end
    Note right of John: Rational thoughts <br/>prevail...
    John-->Alice: Great!
    John->Bob: How about you?
    Bob-->John: Jolly good!
```
