+    <h2>Container image location</h2>
+    <p>The container is uploaded to
+      harbor.k8s.ungleich.ch docker hub. You can find more information
+      about it in the build script
+      on <a href="https://code.ungleich.ch/ungleich-public/ungleich-containers">code.ungleich.ch</a>

+    <h2>Usage</h2>
+    Usually used on brand new machines that have SSH on, but do not
+    necessarily allow root access using password authentication. In
+    this context it is easy to "just get my key" for bootstrapping as
+    follows:
+
+    <pre>
+      # You can use something like curl or wget
+      curl -s key.wf/yourname >> ~/.ssh/authorized_keys
+      wget -q -O - key.wf/yourname >> ~/.ssh/authorized_keys
+    </pre>
+    <h2>Hosting and security information</h2>
+    <p>This service is provided as-is and does not come with any
+      guarantees. This service is hosted by
+      <a href="https://ungleich.ch">ungleich</a> and you should only
+      use it at your own risk.
