+### Configure customization options
+
+You can use the following options to update the `logzio-metrics-collector` Helm chart values [parameters](https://github.com/logzio/logzio-helm/blob/master/charts/logzio-metrics-collector/VALUES.md): 
+
+To modify values found in the `logzio-metrics-collector` sub chart, use the `--set` flag with the `logzio-metrics-collector` prefix.
+
+For example, for a parameter called `someField` in the `logzio-metrics-collector`'s `values.yaml` file, set it by adding the following to the `helm install` / `helm upgrade`  command:
+
+```shell
+--set logzio-metrics-collector.someField="my new value"
+```
