+========================
+EDPM bootc image builder
+========================
+
+To build a CentOS-9-Stream based bootc EDPM container image, run the following
+command::
+
+    export EDPM_BOOTC_REPO=quay.io/<account>/edpm-bootc
+    make build
+    sudo podman push $EDPM_BOOTC_REPO:latest
+
+To convert this container image to ``output/edpm-bootc.qcow2``, run the
+following command::
+
+    make edpm-bootc.qcow2
+
+To package ``edpm-bootc.qcow2`` inside a container image EDPM baremetal
+deployment, run the following command::
+
+    make package
+    sudo podman push $EDPM_BOOTC_REPO:latest-qcow2
+
+To deploy EDPM baremetal with this image, customize the ``baremetalSetTemplate`` with::
+
+    kind: OpenStackDataPlaneNodeSet
+    spec:
+    baremetalSetTemplate:
+        osContainerImageUrl: quay.io/<account>/edpm-bootc:latest-qcow2
+        osImage: edpm-bootc.qcow2
+
