How to upload/publish my ppt file in your site?

Dear friends,

I am new to Zoho.

I have a PowerPoint presentation with 11 slides, file ppt, that I need to show in the web.

The general idea it is to include a link in my website, directly to my presentation in your service.

But I have some questions:

How to upload my ppt?

What url I get, to include in my site?

Your service is free or paid?

Thanks!
