JS Sequence Diagram Plugin

Install the JS Sequence Diagram plugin via NPM, which should be installed globally using the -g option:

$ npm install gitbook-plugin-js-sequence-diagram -g

As you are installing globally, you may need to put sudo in front of the command, sudo npm install gitbook-plugin-js-sequence-diagram -g

To use the plugin in your Gitbook project, add the plugin to the book.json file.

{
    "plugins": ["js-sequence-diagram"]
}

Then, to include a sequence diagram, just wrap your definition in a "sequence" code block. For example:

``` sequence
Title: Here is a title
A->B: Normal line
B-->C: Dashed line
C->>D: Open arrow
D-->>A: Dashed open arrow
```

Please reference the js-sequence-diagrams documentation for details on syntax.
