Here is an example of how to format the data for an A-10C checklist (it is incomplete since it is an example).

checklist:
    -   step: 1. Set EAC Switch
        details: OFF
    -   step: 2. Set RADAR Switch
        details: ON
    -   step: 3. Set VHF radio 1 channel presets 
        details: Configure on VHF 1 Radio Panel (VHF AM).

Below here is the orignal readme.md info from the CMS I am using GRAV, it is what is enabling me to add checklists with such minimal formating required. if you are looking to get in to blogging or something like it I recommend using this, it is a little bit of a learning curve but it is a really nice pice of kit!

Grav is a Fast, Simple, and Flexible, file-based Web-platform. There is Zero installation required. Just extract the ZIP archive, and you are already up and running. It follows similar principles to other flat-file CMS platforms, but has a different design philosophy than most. Grav comes with a powerful Package Management System to allow for simple installation and upgrading of plugins and themes, as well as simple updating of Grav itself.

The underlying architecture of Grav is designed to use well-established and best-in-class technologies to ensure that Grav is simple to use and easy to extend. Some of these key technologies include:

• Twig Templating: for powerful control of the user interface
• Markdown: for easy content creation
• YAML: for simple configuration
• Parsedown: for fast Markdown and Markdown Extra support
• Doctrine Cache: layer for performance
• Pimple Dependency Injection Container: for extensibility and maintainability
• Symfony Event Dispatcher: for plugin event handling
• Symfony Console: for CLI interface
• Gregwar Image Library: for dynamic image manipulation

• PHP 5.6.4 or higher. Check the required modules list
• Check the Apache or IIS requirements

These are the options to get Grav:

You can download a ready-built package from the Downloads page on https://getgrav.org

You can create a new project with the latest stable Grav release with the following command:

$ composer create-project getgrav/grav ~/webroot/grav

1. Clone the Grav repository from https://github.com/getgrav/grav to a folder in the webroot of your server, e.g. ~/webroot/grav. Launch a terminal or console and navigate to the webroot folder:

   $ cd ~/webroot
   $ git clone https://github.com/getgrav/grav.git
   

2. Install the plugin and theme dependencies by using the Grav CLI application bin/grav:

   $ cd ~/webroot/grav
   $ bin/grav install
   

Check out the install procedures for more information.

You can download plugins or themes manually from the appropriate tab on the Downloads page on https://getgrav.org, but the preferred solution is to use the Grav Package Manager or GPM:

$ bin/gpm index

This will display all the available plugins and then you can install one or more with:

$ bin/gpm install <plugin/theme>

To update Grav you should use the Grav Package Manager or GPM:

$ bin/gpm selfupgrade

To update plugins and themes:

$ bin/gpm update

First install the dev dependencies by running composer update from the Grav root. Then composer test will run the Unit Tests, which should be always executed successfully on any site. Windows users should use the composer test-windows command. You can also run a single unit test file, e.g. composer test tests/unit/Grav/Common/AssetsTest.php
