+# 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:

+# OpenAPI generated server
+
+Spring Boot Server
+
+## Overview
+This server was generated by the [OpenAPI Generator](https://openapi-generator.tech) project.
+By using the [OpenAPI-Spec](https://openapis.org), you can easily generate a server stub.
+This is an example of building a OpenAPI-enabled server in Java using the SpringBoot framework.
+
+
+The underlying library integrating OpenAPI to Spring Boot is [springdoc](https://springdoc.org).
+Springdoc will generate an OpenAPI v3 specification based on the generated Controller and Model classes.
+The specification is available to download using the following url:
+http://localhost:8080/v3/api-docs/
+
+Start your server as a simple java application
+
+You can view the api documentation in swagger-ui by pointing to
+http://localhost:8080/swagger-ui.html
+
+Change default port value in application.properties
