+# Terraform config for drone
+Drone is a self-hosted Continuous Integration platform. This terraform root module will create a Gitea OAuth2 application, a persistent volume for Drone and installs Drone to a Kubernetes namespace on Lawndale.
+
+**This module assumes Lawndale as the hosting environment!**
+
+## Provider configurations
+The following providers are used and should be configured before calling `init` or `apply`.
+
+### AWS
+AWS is only used for state backend. Check out [AWS Provider config](https://registry.terraform.io/providers/hashicorp/aws/latest/docs#authentication-and-configuration).
+
+### Gitea
+Either `GITEA_TOKEN` or `GITEA_USERNAME` and `GITEA_PASSWORD` must be set for authentication.
+
+### Kubernetes / Helm
+Drone is provisioned with Helm on a kubernetes cluster.
+
+Helm is using the same environment variables as the Kubernetes provider.
+
+Set `KUBE_CONFIG_PATH` to use a kubeconfig file, and `KUBE_CTX` to use a different context than set in the kubeconfig.
+
+For token auth, set `KUBE_TOKEN` and `KUBE_HOST` environment vars. 
+
+A PEM-encoded root certificates bundle for TLS authentication can be sourced by setting 
+`KUBE_CLUSTER_CA_CERT_DATA`.
