+In order to use certServiceClient it is needed do define certificates array in target component values.yaml. Each
+certificate will be requested from separate init container
+
+Minimum example of array in target component values.yaml:
+certificates:
+  - mountPath:  /var/custom-certs
+    commonName: common-name
+
+Full example (other fields are ignored):
+certificates:
+  - mountPath:  /var/custom-certs
+    caName: RA
+    outputType: JKS
+    commonName: common-name
+    dnsNames:
+      - dns-name-1
+      - dns-name-2
+    ipAddresses:
+      - 192.168.0.1
+      - 192.168.0.2
+    emailAddresses:
+      - email-1@onap.org
+      - email-2@onap.org
+    uris:
+      - http://uri-1.onap.org
+      - http://uri-2.onap.org
+    subject:
+      organization: Linux-Foundation
+      country: US
+      locality: San Francisco
+      province: California
+      organizationalUnit: ONAP
+
+There also need to be some includes used in a target component deployment (indent values may need to be adjusted):
+  1. In initContainers section:
+    {{ include "common.certServiceClient.initContainer" . | indent 6 }}
+  2. In volumeMounts section of container using certificates:
+    {{ include "common.certServiceClient.volumeMounts" . | indent 10 }}
+  3. In volumes section:
+    {{ include "common.certServiceClient.volumes" . | indent 8 }}
