+# Rocky Linux OSTree
+
+This repository contains the configuration files needed to spin Rocky Linux using rpm-ostree.
+
+## Project Structure
+- `manifest.$releasever-$rltype.yaml` - These files represent the entry point for a given release config.
+- `manifests/rocky-common.yaml` - Default configuration for rpm-ostree and rocky common to all variants.
+- `manifests/arch` - These files contain configuration specific to the named architecture, x86_64, aarch64, aarch64-pi. Note these should be explicitly included by top level manifests.
+- `manifests/dnf-groups` - Contains lists of packages organized by containing dnf group, e.g., @Core, @Standard, etc.  This is not a comprehensive list and my not be the best approach.
+- `build` - Contains instructions and scripts to build both the server-side tree and an installation ISO. See the `build/README.md` for build instructions.
+- `kickstarts` - Anaconda kickstart files that can be used with any anaconda installer image.
+
+For details on these manifests, A.K.A. Treefiles, see: [Treefile Reference](https://coreos.github.io/rpm-ostree/treefile/)

+## How to Build
+
+### Notes on Building
+- At the moment this config is built manually using the commands below.  The end goal will be to incorporate this
+into [Empanadas](https://github.com/rocky-linux/sig-core-toolkit).  That being said the build tools provided here should
+be considered a proof of concept at best, and will most likely be removed in the future.
+- Depending on your setup, you may need to run the following commands as root.
+
+### Tree & ISO
+```
+make
+```
+Composes an ostree commit based on the current config, updates the local repo, then creates an installation ISO which embeds the
+local repo.  For more control continue reading.
+
+### Tree Composition
+```
+make init
+```
+Sanitizes the build env and creates an empty ostree repo.  This step is only needed if you want to start
+fresh. If you wish to build commits on top of existing rocky ostree create a mirror. See `make mirror`.
+
+```
+make mirror
+```
+Sanitizes the build env and mirror the ostree from the rockylinux.org remote. This is useful when you want a known working
+starting point to commit on top of.
+
+```
+make tree
+```
+Composes a new tree commit based on the current manifest(s).  At the moment, this is hardcoded to compose `../manifest.8-minimal.yaml`.
+
+### Installer ISO
+```
+make iso
+```
+Creates an installation ISO of the current local tree in `./repo`.
+
+#### Notes
+1. The resulting ISO embeds the newest tree commit (depth 0). Currently, this is hardcoded to the `.../minimal/devel` ref.
+2. The resulting ISO is a standard anaconda installer which will require the user to config users, network, etc. The "special sauce"
+   is the embedded kickstart file that calls `ostreesetup ...`. See `/lorax-templates/lorax-configure-repo.tmpl` or `kickstarts/rockylinux-8-x86_64-minimal-devel.ks` .
+
+### Host Local Repo Server
+```
+make test-server
+```
+Deploys a nginx container to host `./repo` for testing purposes. 
+
+Note that you will need to manually add a remote to your ostree installation for this test server. This can be done like so:
+```
+ostree remote add --no-gpg-verify test-server http://your.ip.address.here:9001/
+```
+
+From there you can rebase your installation to the test server like so:
+```
+rpm-ostree rebase --remote test-server -b rockylinux/8/x86_64/minimal/devel
+```

+# dnf-groups
+These manifest files are organized so that each file represents a DNF group and lists the packages from that group. 
+This may seem unnecessary, and in the end it doesn't really matter, but when thinking about rocky ostree in terms of 
+a rocky minimal clone it is helpful.  Note that at the moment only mandatory and default packages from these groups are 
+included.
+
+### Note About Excluded Packages
+You will notice that a handful packages are commented out.  Some of which have corresponding comments that explain why 
+they are excluded. If something is excluded without a comment it was most likely because it fell into the category of 
+"when its included rpm-ostree freaks out or the produced build is broken". In some cases these packages should be 
+included and warrant further investigation, however, others will probably be left out in the end regardless.
