Sorry it's my first time documentation, and I'd firstly posted a patch as requested which as waited 2 days without response or comments.
So I tried to build the doc and found no error. My mother language is French (as we can see in the comments of the extension i must translate them to English) so, I'll try to give more attention to typos, thanks for the patch. The extension must still evolve although it's able to do what we need some operations and limits are still in it so the documentation will be enhanced. I'll try to use vi to edit the next versions because I see some tabs in the files. I hope this documentation will be useful (I'll translate it to French, and try to make less typos :/) Thanks for your Help, Xavier PS: I'm committing the changes
