The documentation does not say how to use it?

[vikaskedia]

I tried 2 different options:

Option1: Using it with the code fence

Inside the gitbook I wrote the content:

graph TD;
    A-->B;

Loading

And once the bitbook was built all I got was a code fence inside the gitbook instead of the diagram:

Option2: Using it with a block

Inside the gitbook I wrote the content:

{% mermaid %}
graph TD;
A-->B;
{% endmermaid %}

gitbook build gives error

This works.

```graph
 graph TD;
   A-->B;
   A-->C;
   B-->D;
   C-->D;
```
