 This directory contains some example Kubernetes configurations which are also
 used in automated SPIRE systems tests.
 
-+ [simple sat](simple_sat) - This is a simple configuration that deploys SPIRE server
-  as a StatefulSet and SPIRE agent as a DaemonSet.
-+ [postgres](postgres) - This expands on the **simple** configuration by moving
-  the SPIRE datastore into a Postgres StatefulSet. The SPIRE server is now a
-  stateless Deployment that can be scaled.
++ [simple sat](simple_sat) - This is a simple configuration using the Kubernetes
+  [service account token (SAT) attestor](../../doc/plugin_server_nodeattestor_k8s_sat.md)
+  that deploys SPIRE server as a StatefulSet and SPIRE agent as a DaemonSet.
++ [simple psat](simple_psat) - This is a simple configuration using the
+  Kubernetes
+  [projected service account token (PSAT) attestor](../../doc/plugin_server_nodeattestor_k8s_psat.md)
+  that otherwise deploys SPIRE as in the **simple sat** example.
++ [postgres](postgres) - This expands on the **simple sat** configuration by
