| `global.licenseKey` - `licenseKey` | The [license key](https://docs.newrelic.com/docs/accounts/install-new-relic/account-setup/license-key) for your New Relic Account. This will be the preferred configuration option if both `licenseKey` and `customSecret*` values are specified. | |
14+
| `global.customSecretName` - `customSecretName` | Name of the Secret object where the license key is stored | |
15+

21+
| `priorityClassName` | Scheduling priority of the pod | `nil` |
22+
| `nodeSelector` | Node label to use for scheduling | `nil` |
23+
| `tolerations` | List of node taints to tolerate (requires Kubernetes >= 1.6) | See Tolerations below |
24+
| `updateStrategy` | Strategy for DaemonSet updates (requires Kubernetes >= 1.6) | `RollingUpdate` |
25+
| `serviveAccount.create` | If true, a service account would be created and assigned to the deployment | true |
26+
| `serviveAccount.name` | The service account to assign to the deployment. If `serviveAccount.create` is true then this name will be used when creating the service account | |
27+
28+
## Example
29+
30+
Make sure you have [added the New Relic chart repository.](../../README.md#installing-charts)
31+
32+
Then, to install this chart, run the following command:
33+
34+
```sh
35+
helm install newrelic/newrelic-logging \
36+
--set licenseKey=(your-license-key)
37+
```
38+
39+
## Resources
40+
41+
The default set of resources assigned to the pods is shown below:
42+
43+
```yaml
44+
resources:
45+
limits:
46+
cpu: 500m
47+
memory: 128Mi
48+
requests:
49+
cpu: 250m
50+
memory: 64Mi
51+
```
52+
53+
## Tolerations
54+
55+
The default set of tolerations assigned to our daemonset is shown below:
56+
57+
```yaml
58+
tolerations:
59+
- operator: "Exists"
60+
effect: "NoSchedule"
61+
- operator: "Exists"

Your deployment of the New Relic Kubernetes Logging is complete. You can check on the progress of this by running the following command:
