Scenejs/Render - How to make use of its Render Module?

Question

I created an animation and wanted to export into video. For which there is Render module that i installed via npm.

https://www.npmjs.com/package/@scenejs/render Installation $ npm install @scenejs/render

Usage

basic

$ render -i index.html

It installed without any issues. but when I run the command to export video, it gives following error.

PS C:\Drive\EXS\Anim> render -i index.html
render : The term 'render' is not recognized as the name of a cmdlet, function, script file, or 
operable program. Check the spelling of the name, or if a path was included, verify that the path 
is correct and try again.

+ render -i index.html

    + CategoryInfo          : ObjectNotFound: (render:String) [], CommandNotFoundException
    + FullyQualifiedErrorId : CommandNotFoundException

I don't know when I installed the module, why its command doesn't work. Can anyone please help?

expected result as they say on the profile page should be as following but I'm getting above mentioned error:

Start Rendering
