 ## Installing the chart
 
 To install this chart via the Helm chart repository:
 
-```shell
-helm repo add kosli https://charts.kosli.com/
-helm repo update
-helm install [RELEASE-NAME] kosli/k8s-reporter -f [VALUES-FILE-PATH]
+1. Add the Kosli helm repo
+```shell {.command}
+helm repo add kosli https://charts.kosli.com/ && helm repo update
+```
+
+2. Create a secret for the Kosli API token
+```shell {.command}
+kubectl create secret generic kosli-api-token --from-literal=key=<your-api-key>
+```
+
+3. Install the helm chart
+
+A. To report artifacts running in entire cluster (requires cluster-wide read permissions):
+
+```shell {.command}
+helm install kosli-reporter kosli/k8s-reporter \
+    --set reporterConfig.kosliOrg=<your-org> \
+    --set reporterConfig.kosliEnvironmentName=<your-env-name>
+```
+
+B. To report artifacts running in multiple namespaces (requires cluster-wide read permissions):
+
+```shell {.command}
+helm install kosli-reporter kosli/k8s-reporter \
+    --set reporterConfig.kosliOrg=<your-org> \
+    --set reporterConfig.kosliEnvironmentName=<your-env-name> \
+    --set reporterConfig.namespaces=<namespace1,namespace2>
+```
+
+C. To report artifacts running in one namespace (requires namespace-scoped read permissions):
+
+```shell {.command}
+helm install kosli-reporter kosli/k8s-reporter \
+    --set reporterConfig.kosliOrg=<your-org> \
+    --set reporterConfig.kosliEnvironmentName=<your-env-name> \
+    --set reporterConfig.namespaces=<namespace1> \
+    --set serviceAccount.permissionScope=namespace
