REST API Document Generation with SoapUI

Hello,

This may sound like a weird question , but I wanted to give it a try

I started using soapUI some time back and already made a relatively bigger project with various REST API resource end points,and generated Test suites etc.

And now I am thinking to have an option to make a interactive decent documentation for all those REST API endpoints , so any testers or business people can simply go through it and under stand a bit better on what are the API resources available and what does they do et cetera..

Do we have any workaround or logic available to achieve this relatively easily with the existing soapUI project that I have ?

I have heard we have {{Swagger}} from Smartbear which is extensively for all the API documentation purpose , but do we have option to mix up the Swagger and existing soapUI project to achieve documentation relatively a little easier .

Any idea in general on API documentation , or in the above direction would help me 

Thanks in Advance !

Regards
