 ## How to get CORD Helm charts
 
 ### Donwload the helm-charts repository
 
-### Add the CORD repository to helm
+You can get the CORD helm-chars by cloning the `helm-charts` repository:
+
+```shell
+git clone https://gerrit.opencord.org/helm-charts
+```
+
+> If you have downloaded the CORD code following the
+[Getting the Source Code](../developer/getting_the_code.md) guide,
+you'll find it in `~/cord/helm-charts`.
+
+### Add the CORD repository to helm (NOT YET AVAILABLE)
 
 ```shell
 helm repo add ...
 ```
+
+## CORD example values
+
+As you may have noticed, there is an `example` folder
+in the `helm-chart` repository.
+The files contained in that repository are examples of possible overrides
+to obtain a custom deployment.
+
+For example, it is possible to deploy a single instance of `kafka`,
+for development purposes, by using this value file:
+
+```shell
+helm install --name cord-kafka incubator/kafka -f examples/kafka-single.yaml
+```
