Click on the "Immersion" tab at the top of your screen. Then click on the big blue box "Add a document" in the top right corner on the new screen. Fill in form.

But make sure that you have the rights to that document. I think it has to be under the creative commons license. Or if you own it. You could translate your website.

Just make sure the article is under creative commons or that you have the rights to it :)

Wikipedia is generally under 'creative commons', right?

how do I disable an article?

Thanks for the help.
