This package aim to provide an easy way to record preset for markdown conversion by pandoc. You just have to prepare command lines options in settings, launch the package and you are done !
Just use the command palette and type Pandoc-converter, if you a preset is available for your language, it will be shown and you will able to use it. Then, the package will convert your file and show you your output (and errors if they are any).
You can copy and past default settings to your user settings and modify it the way you want. You will be able to define command line and output format. Feel free to test :)
