-# REST API Server for AUSF API
-
-## Overview
-This API Server was generated by the [OpenAPI Generator](https://openapi-generator.tech) project.
-It uses the [Pistache](https://github.com/oktal/pistache) Framework.
+# OpenXG-AUSF
 
 ## Files organization
-The Pistache C++ REST server generator creates three folders:
-- `api`: This folder contains the handlers for each method specified in the OpenAPI definition. Every handler extracts
-the path and body parameters (if any) from the requests and tries to parse and possibly validate them.
-Once this step is completed, the main API class calls the corresponding abstract method that should be implemented
-by the developer (a basic implementation is provided under the `impl` folder)
-- `impl`: As written above, the implementation folder contains, for each API, the corresponding implementation class,
-which extends the main API class and implements the abstract methods.
-Every method receives the path and body parameters as constant reference variables and a reference to the response
-object, that should be filled with the right response and sent at the end of the method with the command:
-response.send(returnCode, responseBody, [mimeType])
-- `model`: This folder contains the corresponding class for every object schema found in the OpenAPI specification.
-
-The main folder contains also a file with a main that can be used to start the server.
-Of course, is you should customize this file based on your needs
