+# Introduction
+
+This cloud directory is for providing a shim around the `bootc` images to use cloud init. This is important because when using the `bootc install to-filesystem` it wipes the `/etc` directory, which kills any remote connection to a cloud compute resource, as the `ssh` keys required for that connection get removed. Cloud init will take care of generating the new ssh keys required to maintain the connection
+
+# Usage
+
+## Common usage pieces
+
+Currently were focusing support on the bootc images for just `amd64`, but we should have other arch builds coming soon.
+
+### Nvidia
+
+`make cloud VENDOR=nvidia ARCH=amd64`
+
+### Intel
+
+`make cloud VENDOR=intel ARCH=amd64`
+
+### AMD
+
+`make cloud VENDOR=amd ARCH=amd64`
