How to deploy my unity game on facebook?

I made a very simple app for webGL.

So... I have already read and did all the instruction on the facebook developer site but the problem is, I got confused about uploading it on my server...

I went to XAMPP and read how to use a different kinds of cloud services that may fit my needs, I know PHP and JSP but the problem is how would I make a website that host my unity game???

Actually this is just a hunch from reading all the articles that I found so far, can you list out all the things I need to deploy my game?

Example:

• Make your website
• Embed your unity game on that website
• Upload it on a cloud
• Configure your facebook app

• -> put your website's address on the secure host
