+
+## How to build this S2I builder image
+
+### OpenShift
+
+    oc new-build https://github.com/quarkusio/quarkus.git --context-dir=docker/centos-graal-maven-s2i --name quarkus-native-s2i
+
+### Locally
+
+    docker build . -t quarkus-native-s2i
+
+## How to use this
+
+### OpenShift
+
+    oc new-app quarkus-native-s2i~https://github.com/quarkusio/quarkus-quickstarts --context-dir=getting-started-native --name=getting-started-native
+
+Note that GraalVM-based native build are more memory & CPU intensive than regular pure Java builds,
+and you therefore may need to increase the quota for OpenShift's S2I builder containers.
+
+### Locally
+
+    sudo dnf install source-to-image
+
+    s2i build --copy ../../../quarkus-quickstarts/getting-started-native quarkus-native-s2i getting-started-native
+
+    docker run --rm -it -p 8080:8080 getting-started-native
