You are not obliged to contribute any improvements or bug fixes back to the project, but it would be both courteous and greatly appreciated.
Swgger-Suite uses many other open-source projects, almost all of which are also MIT licensed. However, the following are exceptions:
I would like to especially thank the dev team at Reverb, who developed Swagger and Swagger-UI, as well as the dev team at Apigee, who developed the excellent Swagger-Editor and contributed it to the open-source community.
