how do you use Mmm Unity Loader plugin for wordpress?

I am trying to post my unity game on wordpress does anyone know how to do that? specifically with this plugin or are there better plugins?

Step 1. Build your project as webgl, and output it to C: emp\myGame(or wherever you want)

Step 2. Upload that myGame folder to your website via ftp, so that it’s at yoursite.com/myGame

Step 3. In wordpress, create an iframe (either via html or using iframe plugin of some kind) that loads yoursite.com/myGame - and just set the width/height of the iframe to the same size/aspect ratio of your game.
