+# Cloud Templates
+
+This directory contains templated versions of the cloud images. This is
+extremely useful for us to be able to create more variants or modify
+all variants at once if need be.
+
+The general guidelines/ideas work like this:
+
+* Start with a basic name, such as `rocky-${provider}-${variant}.ks`
+* Optionally create additional kickstarts, such as an additional packages file
+* Include the very base as necessary:
+
+    * rocky-cloud-base.ks
+    * rocky-cloud-parts-base.ks or rocky-cloud-parts-lvm.ks
+
+* Include other customizations from another kickstart as necessary, such as an additional packages kickstart
+* bootloader configuration and then final %post ... %end section
+
+The most basic example of our most basic generic cloud image goes like this. See comments for details.
+
+```
+# rocky-genclo-base.ks
+
+# Imports the absolute base for the cloud images. This is general setup settings.
+%include rocky-cloud-base.ks
+
+# Imports partition scheme and creation for the image. This is non-LVM.
+%include rocky-cloud-parts-base.ks
+
+# Imports base packages that all cloud images are expected to have
+%include rocky-cloud-base-packages.ks
+
+# bootloader information, each cloud will have different settings, so better we put it here.
+bootloader --append="console=ttyS0,115200n8 no_timer_check crashkernel=auto net.ifnames=0" --location=mbr --timeout=1
+
+# Anything else can go here that isn't fulfilled by custom or base templates.
+# This can be repos if needed.
+
+# the final post section is done here (we've removed all of it for the sake of the example)
+%post --erroronfail
+. . .
+%end
+```
+
+At the end, you would run run ksflatten, and you now have a customized kickstart.
+
+```
+ksflatten -c rocky-genclo-base.ks -o Rocky-X-GenericCloud-Base.ks
