Allow openshift to work with docker and jib container images

 NOTE: If no registry is set (using `quarkus.container-image.registry`) then `docker.io` will be used as the default.
 
+== Selecting among multiple extensions
+
+It does not make sense to use multiple extension as part of the same build. When multiple container image extensions are present, an error will be raised to inform the user. The user can either remove the uneeded extensions or select one using `application.properties`.
+
+For example, if both `container-image-docker` and `container-image-s2i` are present and the user needs to use `container-image-docker`:

 == Customizing
 
 The following properties can be used to customize the container image build process.

-The command above will trigger an s2i binary build.
+The build that will be performed is an s2i binary build. The input of the build is the jar that has been built locally and the output of the build is an ImageStream that is configured to automatically trigger a deployment.
+
+=== Non S2i Builds
+
+Out of the box the openshift extension is configured to use link:container-image#s2i[container-image-s2i]. However, it's still possible to use other container image extensions like:
+
+- link:container-image#s2i[container-image-docker]
+- link:container-image#s2i[container-image-jib]
+
+When a non-s2i container image extension is used, an ImageStream is created that is pointing to an external `dockerImageRepository`. The image is built and pushed to the registry and the ImageStream populates the tags that are available in the `dockerImageRepository`. 
+
+To select which extension will be used for building the image:

+quarkus.container-image.builder=docker
