+# Swagger Sample App
+
+## Overview
+This is a java project to build a stand-alone server which implements the OpenAPI Spec. You can find out 
+more about both the spec and the framework at http://swagger.io.
+
+This sample is based on CXF and Spring Boot, and provides a minimal example of integration of swagger into a CXF based app.
+
+### To run (with Maven)
+To run the server, run this task:
+
+```
+mvn spring-boot:run
+```
+
+This will start Tomcat embedded on port 8080.
+
+### Testing the server
+Once started, you can navigate to http://localhost:8080/services/openapi.json to view the Swagger Resource Listing.
+This tells you that the server is up and ready to demonstrate Swagger.
+
+Swagger-UI is reachable at: http://localhost:8080/services/api-docs?url=/services/openapi.yaml
