+A container image that contains an OpenJDK runtime suitable for running
+modern web services.
+
+
+== Summary
+
+This container image ships the latest OpenJDK feature release from
+https://jdk.java.net[jdk.java.net] on top of a
+https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/8/html/building_running_and_managing_containers/assembly_types-of-container-images_building-running-and-managing-containers#con_understanding-the-ubi-micro-images_assembly_types-of-container-images[Red
+Hat UBI Micro] base.
+
+The module set was selected for
+https://gerrit.benkard.de/plugins/gitiles/mulkcms2/[MulkCMS 2], which
+is a typical Quarkus application.  It will very likely work for other
+typical Quarkus applications.
+
+
+== Building
+
+[source,shell]
+----
+./prepare
+docker build -t $IMAGE_NAME .
+----
+
+

+
+For example, specifying `ALL-MODULE-PATH` includes all modules
+included in the OpenJDK distribution:
+
+[source,dockerfile]
+----
+RUN /jdk/*/bin/jlink \
+    -J-XX:MaxRAMPercentage=75 \
+    --add-modules ALL-MODULE-PATH \ #<1>
+    --compress=1 \
+    --no-man-pages \
+    --strip-debug \
+    --output /java
+----
+<1> Include all JDK modules.
+
+
+== Usage
+
+[source,shell]
+----
+docker run $IMAGE_NAME java -version
