the description of the hikashop patch is very poor

you know, writing a doc is the worst job of a developper. And if you look you will see that many extensions come without any instruction ! I do my best and I can understand that it is not easy to understand or to read. In this way all comments are welcome to improve or clarify the document. I'm opened to the dialog

now for your problem, you should contact me per email to give me admin access with ftp to the module.
