+# OpenAPI Generator Ignore
+# Generated by openapi-generator https://github.com/openapitools/openapi-generator
+
+# 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

+# openAPIPetstore
+
+This Kotlin based [Spring Boot](https://spring.io/projects/spring-boot) application has been generated using the [OpenAPI Generator](https://github.com/OpenAPITools/openapi-generator).
+
+## Getting Started
+
+This document assumes you have either maven or gradle available, either via the wrapper or otherwise. This does not come with a gradle / maven wrapper checked in.
+
+By default a [`pom.xml`](pom.xml) file will be generated. If you specified `gradleBuildFile=true` when generating this project, a `build.gradle.kts` will also be generated. Note this uses [Gradle Kotlin DSL](https://github.com/gradle/kotlin-dsl).
+
+To build the project using maven, run:
+```bash
+mvn package && java -jar target/openapi-spring-1.0.0.jar
+```
+
+To build the project using gradle, run:
+```bash
+gradle build && java -jar build/libs/openapi-spring-1.0.0.jar
+```
+
+If all builds successfully, the server should run on [http://localhost:8080/](http://localhost:8080/)
