+# REST API Server for {{appName}}
+
+## Overview
+This API Server was generated by the [OpenAPI Generator](https://openapi-generator.tech) project.
+It uses the [Restbed](https://github.com/Corvusoft/restbed) Framework.
+
+
+## Installation
+Put the package under your project folder and import the API stubs.
+You need to complete the server stub, as it needs to be connected to a source.
+
+
+## Libraries required
+boost_system
+ssl (if Restbed was built with SSL Support)
+crypto
+pthread
+restbed
+
+
+## Namespaces
+{{{apiPackage}}}
+{{{modelPackage}}}

+# Use this file to prevent files from being overwritten by the generator.
+# The patterns follow closely to .gitignore or .dockerignore.
+
+# As an example, the C# client generator defines ApiClient.cs.
+# You can make changes and tell OpenAPI Generator to ignore just this file by uncommenting the following line:
+#ApiClient.cs
+
+# You can match any string of characters against a directory, file or extension with a single asterisk (*):
+#foo/*/qux
+# The above matches foo/bar/qux and foo/baz/qux, but not foo/bar/baz/qux
+
+# You can recursively match patterns against a directory, file or extension with a double asterisk (**):
+#foo/**/qux
+# This matches foo/bar/qux, foo/baz/qux, and foo/bar/baz/qux
+
+# You can also negate patterns with an exclamation (!).
+# For example, you can ignore all files in a docs folder with the file extension .md:
+#docs/*.md
+# Then explicitly reverse the ignore rule for a single file:
+#!docs/README.md

+# REST API Server for OpenAPI Petstore
+
+## Overview
+This API Server was generated by the [OpenAPI Generator](https://openapi-generator.tech) project.
+It uses the [Restbed](https://github.com/Corvusoft/restbed) Framework.
+
+
+## Installation
+Put the package under your project folder and import the API stubs.
+You need to complete the server stub, as it needs to be connected to a source.
+
+
+## Libraries required
+boost_system
+ssl (if Restbed was built with SSL Support)
+crypto
+pthread
+restbed
+
+
+## Namespaces
+org.openapitools.server.api
+org.openapitools.server.model
+
+
+## Example
+
+The handler functionality can be implemented in two different ways.
+Either inherit the given resource and override the handler methods.
+Or set a handler lambda to a resource.
+
+This example shows how this can be done with the pet store API.
+
+```
+#include "api/StoreApi.h"
+#include "api/UserApi.h"
+
+using namespace org::openapitools::server::api;
+using namespace org::openapitools::server::api::StoreApiResources;
+using namespace org::openapitools::server::api::UserApiResources;
+
+/* 1. variant: inherit from the resource and override handler method */
+class MyStoreApiStoreOrderResource : public StoreOrderResource {
+public:
+    std::pair<int, Order>
+    handler_POST(Order &order) override {
+        auto ret = Order();
+        /* ... add your implementation here .... */
+        return std::make_pair(200, ret);
+    }
+};
+
+int main() {
+    const auto service = std::make_shared<restbed::Service>();
+
+    auto storeApi = StoreApi(service);
+    storeApi.setResource(std::make_shared<MyStoreApiStoreOrderResource>());
+
+    auto userApi = UserApi(service);
+    /* 2. variant: implement handler as lambda */
+    userApi.getUserResource()->handler_POST_func = [](auto& user) {
+        /* ... add your implementation here .... */
+        return 200;};
+
+    const auto settings = std::make_shared<restbed::Settings>();
+    settings->set_port(1236);
+
+    service->start(settings);
+}
