 If you already have an existing API and you just want to generate the swagger documentation from it, there are a couple easy steps to make it work. First off, you should be familiar with Swagger and, in particular, with [swagger-core](https://github.com/swagger-api/swagger-core). Assuming that you coded your REST API using JAX-RS, based on which was your library of choice (Jersey or RESTEasy), there are several [guides](https://github.com/swagger-api/swagger-core/wiki/Swagger-Core-JAX-RS-Project-Setup-1.5.X) available to get you set up very fast.
