+#### Configure Collectd Plugins
+1. Using the sample [collectdglobal.yaml](microservices/collectd-operator/examples/collectd/collectdglobal.yaml), Configure the CollectdGlobal CR
+2. If there are additional Types.db files to update, Copy the additional types.db files to resources folder. 
+3. Create a ConfigMap to load the types.db and update the configMap with name of the ConfigMap created.
+4. Create and configure the required CollectdPlugin CRs. Use these samples as a reference [cpu_collectdplugin_cr.yaml](microservices/collectd-operator/examples/collectd/cpu_collectdplugin_cr.yaml), [prometheus_collectdplugin_cr.yaml](microservices/collectd-operator/examples/collectd/prometheus_collectdplugin_cr.yaml).
+4. Use the same namespace where the collection package was installed.
+5. Assuming it is edge1, create the config resources that are applicable. Apply the following commands in the same order.
+```yaml
+# Note: 
+## 1. Create Configmap is optional and required only if additional types.db file needs to be mounted.
+## 2. Add/Remove --from-file accordingly. Use the correct file name based on the context.
+kubectl create configmap typesdb-configmap --from-file ./resource/[FILE_NAME1] --from-file ./resource/[FILE_NAME2]
+kubectl create -f edge1 collectdglobal.yaml
+kubectl create -f edge1 [PLUGIN_NAME1]_collectdplugin_cr.yaml
+kubectl create -f edge1 [PLUGIN_NAME2]_collectdplugin_cr.yaml
+kubectl create -f edge1 [PLUGIN_NAME3]_collectdplugin_cr.yaml
