+## Retrieving SSH Authorized Keys
+
+### From a GitHub User
+
+Using the `coreos-ssh-import-github` field, we can import public SSH keys from a GitHub user to use as authorized keys to a server.
+
+```yaml
+#cloud-config
+
+users:
+  - name: elroy
+    coreos-ssh-import-github: elroy
+```
+
+### From an HTTP Endpoint
+
+We can also pull public SSH keys from any HTTP endpoint which matches [GitHub's API response format](https://developer.github.com/v3/users/keys/#list-public-keys-for-a-user).
+For example, if you have an installation of GitHub Enterprise, you can provide a complete URL with an authentication token:
+
+```yaml
+#cloud-config
+
+users:
+  - name: elroy
+    coreos-ssh-import-url: https://github-enterprise.example.com/api/v3/users/elroy/keys?access_token=<TOKEN>
+```
+
+You can also specify any URL whose response matches the JSON format for public keys:
+
+```yaml
+#cloud-config
+
+users:
+  - name: elroy
+    coreos-ssh-import-url: https://example.com/public-keys

+The `coreos.etcd2.*` parameters will be translated to a partial systemd unit acting as an etcd configuration file.
+If the platform environment supports the templating feature of coreos-cloudinit it is possible to automate etcd configuration with the `$private_ipv4` and `$public_ipv4` fields. When generating a [discovery token](https://discovery.etcd.io/new?size=3), set the `size` parameter, since etcd uses this to determine if all members have joined the cluster.
