+# quarkus-grpc-hello
+
+This project uses Quarkus, the Supersonic Subatomic Java Framework.
+
+If you want to learn more about Quarkus, please visit its website: https://quarkus.io/ .
+
+## Running the application in dev mode
+
+You can run your application in dev mode that enables live coding using:
+```shell script
+./mvnw compile quarkus:dev
+```
+
+> **_NOTE:_**  Quarkus now ships with a Dev UI, which is available in dev mode only at http://localhost:8080/q/dev/.
+
+## Packaging and running the application
+
+The application can be packaged using:
+```shell script
+./mvnw package
+```
+It produces the `quarkus-run.jar` file in the `target/quarkus-app/` directory.
+Be aware that it’s not an _über-jar_ as the dependencies are copied into the `target/quarkus-app/lib/` directory.
+
+The application is now runnable using `java -jar target/quarkus-app/quarkus-run.jar`.
+
+If you want to build an _über-jar_, execute the following command:
+```shell script
+./mvnw package -Dquarkus.package.jar.type=uber-jar
+```
+
+The application, packaged as an _über-jar_, is now runnable using `java -jar target/*-runner.jar`.
+
+## Creating a native executable
+
+You can create a native executable using: 
+```shell script
+./mvnw package -Dnative
+```
+
+Or, if you don't have GraalVM installed, you can run the native executable build in a container using: 
+```shell script
+./mvnw package -Dnative -Dquarkus.native.container-build=true
+```
+
+You can then execute your native executable with: `./target/quarkus-grpc-hello-1.0.0-SNAPSHOT-runner`
+
+If you want to learn more about building native executables, please consult https://quarkus.io/guides/maven-tooling.
