[Anurag-Bansode]

Hi @SrinjoyeeDey .
I have add the documentation for the backend; the developer just have to follow the template in previous code and same can be available on http://localhost:4000/api-docs
Frontend developer the can create exact objects which can also be tested via Swaggers Testing mechanism

Additional changes have been mention in readme.md

Just for Reference

Backend Documentations:

The Backend Documentation is generated using SwaggerUI
run

npm run dev

command
and now the documentation is available at http://localhost:4000/api-docs.
Frontend developer can refer to the same to create json objects.

Frontend Documentations:

The Frontend Documentation is generated using Typedoc and tsdocs and can be build using

npm run docs

command.

The outputed static files will be available in /docs folder

The diff is long however all are just comments.

Please Note: changes have been made to package.json which include the following

Frontend: in scripts - new script added for doc generation
Backend: two swagger packages have been added

closes #68
