Process to **add new or edit existing** markdown files to AGL documentation:

## Directory Structure

Find existing or add new markdowns in the following directory structure.

```sh
documentation
├── docs
│   ├── 0_Getting_Started
│   │   ├── 1_Quickstart
│   │   └── 2_Building_AGL_Image
|   ├── .....
|   |
|   ├──<Chapter-Number>_<Chapter-Name>
|   |   ├──<Subchapter-Number>_<Subchapter-Name>
|   |   |   ├──<Index-Number>_<Markdown-Title>.md
|   |   |   ├── .....
```

## Markdown Formatting

  1. Add following at the start of each markdown :

    ```sh
    ---
    title: <enter-title>
    ---
    ```

  2. Internal Linking :

    ```sh
    [<enter-title>](../<Chapter-Number>_<Chapter-Name>/<Subchapter-Number>_<Subchapter-Name>/<Index-Number>_<Markdown-Title>.md)
    ```

## Test Hyperlinks

[LinkChecker](https://wummel.github.io/linkchecker/) is a tool that allows to
check all the hyperlinks in the site.

For testing hyperlinks as soon as the local site is running, do:

```sh
$ linkchecker http://localhost:8000
```

The ```linkchecker``` output will display the broken link and there location in
the site.
