Where is the online documentation for the plugin?

Hello, I am surprised (for professional plugin) not finding documentation. I thought I could start working on it again tonight. But I'll have to give up and wait! it starts well! In fact, it starts badly: Your cleients aps necessarily have the time to wait before you can start using a tool. By cons, to buy, no problem: There is so much at once, it pollutes us entry into the same space on the WP install ... Please tell me where I can find this online document. Thank you.YR

PS: In the meantime I 'lai simply remove altogether. and perhaps I set aside my contract with you. Because I find it inadmisible. For it is indamissible: Normally such a product should be delivered with an online manual. No, really, this is not acceptable.
