It will be discussed in Commonalities, but it can be helpful to provide also link to Swagger Editor to render the yaml for displaying the documentation: https://editor.swagger.io/?url=https://raw.githubusercontent.com/camaraproject/HomeDevicesQoD/release-0.2.0/code/API_definitions/home_devices_qod.yaml Then the user can choose his preferred on-line tool.

I've added the Swagger Editor link in cfa1626. And CHANGELOG.md has been updated as well. In any case, I will wait for final agreement in Commonalities to do the same. Eventually the releases should also be updated with the same info as CHANGELOG.md.
