+# AWS IAM Authenticator
+
+See https://github.com/kubernetes-sigs/aws-iam-authenticator
+
+In particular, make sure that have configured your API server as in
+https://github.com/kubernetes-sigs/aws-iam-authenticator#how-do-i-use-it. (This
+chart only installs the DaemonSet and a ConfigMap.)
+
+## Values
+
+| Config                  | Description               | Default                                  |
+| `image.repository`      | Image repo                | `gcr.io/heptio-images/authenticator`     |
+| `image.tag`             | Image tag                 | `v0.1.0`                                 |
+| `image.pullPolicy`      | Image pull policy         | `IfNotPresent`                           |
+| `config`                | All the config, see below | `{}`                                     |
+| `resources`             | Pod resources             | `{}`                                     |
+| `hostPathConfig.output` | HostPath output           | `/srv/kubernetes/aws-iam-authenticator/` |
+| `hostPathConfig.state`  | HostPath state            | `/srv/kubernetes/aws-iam-authenticator/` |
+
+### Config
+
+The value set for `config` is where all the action happens - this is
+how you map AWS IAM roles to groups in the cluster. See the
+aws-iam-authenticator docs for all of the possible options for this.
+
+A simple example values file might look like:
+```
+config:
+  clusterID: mycluster.io
+  server:
+    mapRoles:
+    - groups:
+      - developers  # the name of a group within Kubernetes
+      roleARN: arn:aws:iam::000000000000:role/developer  # the ARN of a role in AWS
+      username: developer
+```
