+# Rocky Red Quartz Builds
+
+This directory contains Packer configuration for building Rocky 10 (Red Quartz)
+
+### Overview
+
+These builds use a multi-stage Packer workflow:
+
+- The first stage creates a minimal base image from the installer ISO
+- The second stage reuses that base image to produce a Vagrant-ready box
+
+### Usage
+
+Build the base qemu image:
+
+    make base
+
+Build vagrant image:
+
+    make vagrant
+
+Package vagrant box:
+
+    make package
+
+Build with visible console:
+
+    make base HEADLESS=false
+
+### Publishing
+
+Built boxes from this configuration are published at
+[krislamo.org/rocky10](https://portal.cloud.hashicorp.com/vagrant/discover/krislamo.org/rocky10)
+on Vagrant Cloud
