+## About this repo
+
+Contains slides and some demo code for the Kubecon EU 2020 talk "Ingress on the Rails"
+
+The demo code sets up external-dns using the deployment pattern described in the talk, of calling `helm template | kustomize | kubectl apply` to support multiple K8s clusters. Similar tools are emerging like [helm post-rendering](https://helm.sh/docs/topics/advanced/#post-rendering) and [Ship](https://github.com/replicatedhq/ship)
+
+## Using this code
+
+Hopefully everything works as is on GKE except you need to change the project ID - replace all instances of afirth-kceu2020 with your project ID. Helm 2, sops, and GNU make are required for code generation.
+
+## Clusters
+
+`./clusters` has some scripts to make some GKE clusters if you want to demo this as is.
+
+#TODO
+-add sops image
+-add triggers + info
+-add diffing CI
+-add CD
+-add external-dns
+-add sample ingress

-Included for reproducibility are cluster creation scripts for GKE. These scripts create a basic cluster, add a node pool, and grant cloudbuild permissions.

 It's like infra as code, only worse
