+Overriding certificate stores
+*****************************
+Policy components package default key and trust stores that support https based communication with other
+AAF-enabled ONAP components. Each store can be overridden at installation.
+
+To override a default keystore, the new certificate store (policy-keystore) file should be placed at the
+appropriate helm chart locations below:
+
+* oom/kubernetes/policy/charts/drools/resources/secrets/policy-keystore drools pdp keystore override.
+* oom/kubernetes/policy/charts/policy-apex-pdp/resources/config/policy-keystore apex pdp keystore override.
+* oom/kubernetes/policy/charts/policy-api/resources/config/policy-keystore api keystore override.
+* oom/kubernetes/policy/charts/policy-distribution/resources/config/policy-keystore distribution keystore override.
+* oom/kubernetes/policy/charts/policy-pap/resources/config/policy-keystore pap keystore override.
+* oom/kubernetes/policy/charts/policy-xacml-pdp/resources/config/policy-keystore xacml pdp keystore override.
+
+In the event that the truststore (policy-truststore) needs to be overriden as well, place it at the appropriate
+location below:
+
+* oom/kubernetes/policy/charts/drools/resources/configmaps/policy-truststore drools pdp truststore override.
+* oom/kubernetes/policy/charts/policy-apex-pdp/resources/config/policy-truststore apex pdp truststore override.
+* oom/kubernetes/policy/charts/policy-api/resources/config/policy-truststore api truststore override.
+* oom/kubernetes/policy/charts/policy-distribution/resources/config/policy-truststore distribution truststore override.
+* oom/kubernetes/policy/charts/policy-pap/resources/config/policy-truststore pap truststore override.
+* oom/kubernetes/policy/charts/policy-xacml-pdp/resources/config/policy-truststore xacml pdp truststore override.
+
+When the keystore passwords are changed, the corresponding component configuration ([1]_) should also change:
+
+* oom/kubernetes/policy/charts/drools/values.yaml
+* oom/kubernetes/policy-apex-pdp/resources/config/config.json
+* oom/kubernetes/policy-distribution/resources/config/config.json
+
+This procedure is applicable to an installation that requires either AAF or non-AAF derived certificates.
+The reader is refered to the AAF documentation when new AAF-compliant keystores are desired:
+
+* `AAF automated configuration and Certificates <https://wiki.onap.org/display/DW/Application+Authorization+Framework+%28AAF%29+Documentation>`_.
+* `AAF Certificate Management for Dummies <https://wiki.onap.org/display/DW/AAF+Certificate+Management+for+Dummies>`_.
+* `Instructional Videos <https://wiki.onap.org/display/DW/Instructional+Videos>`_.
+
+After these changes, follow the procedures in the :ref:`install-upgrade-policy-label` section to make usage of
+the new stores effective.
