In order to use it on your server you have to do some minor changes in a few paths and urls.
1st. Change the url parameter in swagger-ui/dist/index.html file. This parameter should point to a resource listing url (e.g. mylocalhost.com/api/api-docs).
2nd. Set a basepath that points to the server where you are going to do the url requests. You can find it in api_doc_server.rb file.
You can find the json files that we use to describe the api resources in the api/v1 folder.
