Nodejs api needs a swagger documentation

Hello, I want to make clear that my budget is based on the fact I need the next requirements to be added to my project and not a full implementation of the Swagger doc - need to add the base of swagger setup - add documentation for 2 endpoints only - be able to provide a guide how to use swagger or and an example from a open source project in Nodejs how to implement swagger. I used swagger once in Laravel but I cannot understand in Node how to do it and the developer i need is someone which can be a guide to me how to do it so that I can continue make it right alone. So please be aware of it in yours proposal and be aware that I will ask for resources to help me to make it so as like in the above points a guide or some open source project where swagger was used so I may have a reference to guide me. Budget max 50$ if is not explained by providing right reasons why should be more If you say 200 saying just that right without explanation of the estimation just don't bother to contact me. Thank you
