Hey there Harsh,

In order to post an item on Alkanyx, now that you are an exclusive author, you'll just have to go to the Upload section and upload your item.

Note that, beside the actual archive of your script, you will also need a thumbnail and a preview image of your product plus documentation.

The items are also processed by a reviewer, but if you take care of these main aspects, you should be good. Adding additional info in description and live demo link are increasing your chances of selling your product.

If you have any more questions, don't hesitate to send me a prive message and I will help you.
