-## Integration tests
-Integration tests are run in phase integration-test. To run them use mvn verify.
+# causeway
 
-Tests are using by default url http://pnc-host/pnc-rest/rest to connect to PNC (you can define IP for pnc-host in your hosts file).
+This project uses Quarkus, the Supersonic Subatomic Java Framework.
 
-Alternatively you can set the value by setting system property PNC_URL (eg. -DPNC_URL=http://my-pnc-host/pnc-rest/rest)
+If you want to learn more about Quarkus, please visit its website: https://quarkus.io/ .
 
-## Disabling integration tests for PNC
-Integration tests for PNC can be disabled by setting -Ddisable-pnc-it
+## Running the application in dev mode
 
-## Dependencies
-To compile causeway you need to compile:
- * https://github.com/project-ncl/pnc
- * https://github.com/release-engineering/kojiji
+You can run your application in dev mode that enables live coding using:
+```shell script
+mvn compile quarkus:dev
+```
 
-## Metrics support
+> **_NOTE:_**  Quarkus now ships with a Dev UI, which is available in dev mode only at http://localhost:8080/q/dev/.
 
-PNC tracks metrics of JVM and its internals via Dropwizard Metrics. The metrics can currently be reported to a Graphite server by specifying as system property or environment variables those properties:
-- metrics\_graphite\_server (mandatory)
-- metrics\_graphite\_port (mandatory)
-- metrics\_graphite\_prefix (mandatory)
-- metrics\_graphite\_interval (optional)
+## Packaging and running the application
 
-If the `metrics_graphite_interval` variable (interval specified in seconds) is not specified, we'll use the default value of 60 seconds to report data to Graphite.
+The application can be packaged using:
+```shell script
+mvn 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 graphite reporter is configured to report rates per second and durations in terms of milliseconds.
+The application is now runnable using `java -jar target/quarkus-app/quarkus-run.jar`.
 
-## OIDC Client Support
-We need to setup an OIDC Client to send back callback information. This is done by defining in the main.conf the following values:
+If you want to build an _über-jar_, execute the following command:
+```shell script
+mvn package -Dquarkus.package.jar.type=uber-jar
+```
 
-- `oidc-client.url`: Base URL of the Keycloak server
-- `oidc-client.realm`: Realm used with Keycloak
-- `oidc-client.client-id`: the client id name
-- `oidc-client.secret-file`: the location of the file that contains the secret
+The application, packaged as an _über-jar_, is now runnable using `java -jar target/*-runner.jar`.
 
-Only client credentials flow is supported for now.
+## Creating a native executable
+
+You can create a native executable using: 
+```shell script
+mvn package -Dnative
+```
+
+Or, if you don't have GraalVM installed, you can run the native executable build in a container using: 
+```shell script
+mvn package -Dnative -Dquarkus.native.container-build=true
+```
+
+You can then execute your native executable with: `./target/causeway-1.0.0-SNAPSHOT-runner`
+
+If you want to learn more about building native executables, please consult https://quarkus.io/guides/maven-tooling.
