+# Java CLI project template
+
+Probably the fastest way to bootstrap a **Java** Command Line Application (**CLI**) project!
+
+Click the big green *Use This Template* button and start building your own CLI.
+
+## 🤩 Highlights
+
+- uses [Picocli](https://picocli.info/) for simple and elegant commands implementation
+- builds to an **executable jar** and **GraalVM Native Image**
+- preconfigured `help` and `version` commands
+- generates Bash/ZSH autocompletion scripts
+- uses **Maven** as a build tool
+- **no frameworks** like Spring, Micronaut or Quarkus
+
+## 🛠 Requirements
+
+- GraalVM distribution of Java (easy to install with https://sdkman.io/)
+
+## 🤔 How to use
+
+Run tests & build an executable JAR:
+
+```
+$ ./mvnw package
+```
+
+Run tests as native image & build a native executable:
+
+```
+$ ./mvnw package -Pnative
+```
+
+Run application through Maven
+
+```
+$ ./mvnw -Dexec.args=--help
+```
+
