## Usage

```bash
npm install -g hads
hads -o
```

Your browser will open `http://localhost:4040` and display your project documentation.

### Command-line options

```
Usage: hads [root dir] [options]

Options:
  -p, --port        Port number to listen on       [default: 4040]
  -h, --host        Host address to bind to        [default: "localhost"]
  -i, --images-dir  Directory to store images      [default: "images"]
  -o, --open        Open default browser on start
  -r, --readonly    Read-only mode (no add or edit feature)
  -e, --export      Export static HTML             [default: "./public"]
  --help            Show this help
```

If no root dir is specified, `./` will be used.

## Extras

### Home page

The server will automatically search for a file named `index.md`, `readme.md` or `README.md` on the specified
documentation root and will use it as your home page.

You can customize the CSS style in a file named `custom.css`.

### Table of contents

The special text `[[toc]]` will be replaced by the table of contents of the markdown document, based on headings.

### Navigation index

The special text `[[index]]` will be replaced by the full navigation index of all markdown files found under the
specified *root dir*. File and folder names will be *humanized* for better readability.

It is particularly useful on the home page to provide an overview of the available documentation for your project.

The sorting of each index level is as follows:
1. Any README.md, readme.md, or index.md is always at the top.
2. All files and folders that are prefixed with a number (e.g. `001-abc` and `002 mno` and `003_xyz`) are next, sorted 
by their respective prefix numbers. Note that the prefix numbers are stripped out in the index.
3. All remaining files, sorted by their name.
4. All remaining folders, sorted by their name.  

### Mermaid Diagrams and flowcharts

You can use the [Mermaid](http://knsv.github.io/mermaid/) syntax to insert diagrams and flowcharts directly in your
markdown, but using code blocks with the `mermaid` language specified, like this:

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

Mermaid [configuration](https://mermaidjs.github.io/mermaidAPI.html) can be overridden on a given page using the global variable `MERMAID_CONFIG` in a `<script>` tag, for example:

```html
<script>
MERMAID_CONFIG = { theme: 'forest' };
</script>
```

## Updates
