# Add custom environment labels

Labeling clusters in your cloud-native environments is very helpful for efficient resource management and observability. By assigning an environment label in groundcover, you can categorize and identify clusters based on any specific criteria that you find helpful. For example, you can choose to label your clusters by environment type (development, staging, production, etc.), or by region (EU, US, etc.).

{% hint style="info" %}
**Default value:** Clusters without a configured environment label will display **"none"** in the Cluster Picker dropdown. This is the platform's default indicator for clusters where the `env` value has not been set.
{% endhint %}

To add an environment label to your cluster, edit your cluster's existing values.yaml and add the following line:

```yaml
env: "my-env-name"
```

Once defined and added, these labels will be available for you to select in the cluster and environment drop down menu ("Cluster Picker").
