 # Customization
 
-To customize clusters in ways that aren't supported by input variables, fork the repo and make changes to the Terraform module. Stay tuned for improvements to this strategy since it is beneficial to stay close to this upstream.
+Typhoon provides minimal Kubernetes clusters with defaults we recommend for production. Terraform variables provide easy to use and supported customizations for clusters. Advanced options are available for customizing the architecture or hosts.
+
+## Variables
+
+Typhoon modules accept Terraform input variables for customizing clusters in meritorious ways (e.g. `worker_count`, etc). Variables are carefully considered to provide essentials, while limiting complexity and test matrix burden. See each platform's tutorial for options.
+
+## Addons
+
+Clusters are kept to a minimal Kubernetes control plane by offering components like Nginx Ingress Controller, Prometheus, Grafana, and Heapster as optional post-install [addons](https://github.com/poseidon/typhoon/tree/master/addons). Customize addons by modifying a copy of our addon manifests.
+
+## Hosts
+
+### Container Linux
+
+!!! danger
+    Container Linux Configs provide powerful host customization abilities. You are responsible for the additional configs defined for hosts.
+
+Container Linux Configs (CLCs) declare how a Container Linux instance's disk should be provisioned on first boot from disk. CLCs define disk partitions, filesystems, files, systemd units, dropins, networkd configs, mount units, raid arrays, and users. Typhoon creates controller and worker instances with base Container Linux Configs to create a minimal, secure Kubernetes cluster on each platform.
+
+Typhoon AWS, Google Cloud, and Digital Ocean give users the ability to provide CLC *snippets* - valid Container Linux Configs that are validated and additively merged into the Typhoon base config during `terraform plan`. This allows advanced host customizations and experimentation.
+
+#### Examples
+
+Container Linux [docs](https://coreos.com/os/docs/latest/clc-examples.html) show many simple config examples. Ensure a file `/opt/hello` is created with permissions 0644. 
+
+```
+# custom-files
+storage:
+  files:
+    - path: /opt/hello
+      filesystem: root
+      contents:
+        inline: |
+          Hello World
+      mode: 0644
+```
+
+Ensure a systemd unit `hello.service` is created and a dropin `50-etcd-cluster.conf` is added for `etcd-member.service`.
+
+```
+# custom-units
+systemd:
+  units:
+    - name: hello.service
+      enable: true
+      contents: |
+        [Unit]
+        Description=Hello World
+        [Service]
+        Type=oneshot
+        ExecStart=/usr/bin/echo Hello World!
+        [Install]
+        WantedBy=multi-user.target
+    - name: etcd-member.service
+      enable: true
+      dropins:
+        - name: 50-etcd-cluster.conf
+          contents: |
+            Environment="ETCD_LOG_PACKAGE_LEVELS=etcdserver=WARNING,security=DEBUG"
+```
+
+#### Specification
+
+View the Container Linux Config [format](https://coreos.com/os/docs/1576.4.0/configuration.html) to read about each field.
+
+#### Usage
+
+Write Container Linux Configs *snippets* as files in the repository where you keep Terraform configs for clusters (perhaps in a `clc` or `snippets` subdirectory). You may organize snippets in multiple files as desired, provided they are each valid.
+
+Define an [AWS](https://typhoon.psdn.io/aws/#cluster), [Google Cloud](https://typhoon.psdn.io/google-cloud/#cluster), or [Digital Ocean](https://typhoon.psdn.io/digital-ocean/#cluster) cluster and fill in the optional `controller_clc_snippets` or `worker_clc_snippets` fields.
+
+```
+module "digital-ocean-nemo" {
+  ...
+
+  controller_count        = 1
+  worker_count            = 2
+  controller_clc_snippets = [
+    "${file("./custom-files")}",
+    "${file("./custom-units")}",
+  ]
+  worker_clc_snippets = [
+    "${file("./custom-files")}",
+    "${file("./custom-units")}",
+  ]
+  ...
+}
+```
+
+Plan the resources to be created.
+
+```
+$ terraform plan
+Plan: 54 to add, 0 to change, 0 to destroy.
+```
+
+Most syntax errors in CLCs can be caught during planning. For example, mangle the indentation in one of the CLC files:
+
+```
+$ terraform plan
+...
+error parsing Container Linux Config: error: yaml: line 3: did not find expected '-' indicator
+```
+
+Undo the mangle. Apply the changes to create the cluster per the tutorial.
+
+```
+$ terraform apply
+```
+
+Container Linux Configs (and the CoreOS Ignition system) create immutable infrastructure. Disk provisioning is performed only on first boot from disk. That means if you change a snippet used by an instance, Terraform will (correctly) try to destroy and recreate that instance. Be careful!
+
+!!! danger
+    Destroying and recreating controller instances is destructive! etcd runs on controller instances and stores data there. Do not modify controller snippets. See [blue/green](https://typhoon.psdn.io/topics/maintenance/#upgrades) clusters.
+
+## Architecture
+
+To customize clusters in ways that aren't supported by input variables, fork Typhoon and maintain a repository with customizations. Reference the repository by changing the username.
+
+```
+module "digital-ocean-nemo" {
+  source = "git::https://github.com/USERNAME/typhoon//digital-ocean/container-linux/kubernetes?ref=myspecialcase"
+  ...
+}
+```
