 It works on [wkhtmltopdf](http://wkhtmltopdf.org/) . ``dj-wkhtmltopdf`` will allow user to organize their own pdf generator through django admin without any deployment :).
 
-Mainly I was inspired by [django-wkhtmltopdf](https://github.com/incuna/django-wkhtmltopdf) . When I am working on Eccomerce project we want to generate invoice for orders.So we preferred wkhtmltopdf for pdf generator using django-wkhtmltopdf wrapper.
