 [Sysdig Stackdriver Bridge](https://docs.sysdig.com/en/kubernetes-audit-logging.html#UUID-f62c275e-389a-317f-2079-2c61d1f282a7_UUID-ded20060-405c-1f5f-4b3f-c18d20b5668d) is an extension of the Sysdig tool that reads audit logs from Stackdriver, reformats them to match the Kubernetes-native format, and sends the logs to a configurable webhook and to the Sysdig agent service.
 
-## Introduction
 
 This chart adds the Sysdig Stackdriver Bridge application into a cluster using a simple `Deployment` with a `ConfigMap`.
 
 ## Prerequisites
 
-- Sysdig should be deployed in the target Kubernetes cluster.
-- You will need to create a secret that matches the value `secret.name` (`stackdriver-webhook-bridge` by default) that contains the key `key.json` with the value of the created GCP IAM Service Account for Sysdig to access Stackbridge.
-- It is recommended to create this `Secret` in an out-of-band fashion in CI/CD, etc.
-  - Optionally, you can enable creation of the `Secret` via the chart by setting `secret.create=true` and providing the JSON data directly via `secret.data`. **This is not an advisable approach for production systems.**

 ## Configuration
 
+You can use the Helm chart to update the default Sysdig Stackdriver Bridge configurations by using either of the following:
+
+- Using the key-value pair: `--set sysdig.settings.key = value`
+- `values.yaml` file
+
+### Using the Key-Value Pair
+
+Specify each parameter using the `--set key=value[,key=value]` argument to the `helm install` command.
+
+For example:
+
+```bash
+$ helm install --name my-release \
+    --set bridge.forwardURL=FOO,bridge.pollInterval=60s \
+    sysdiglabs/sysdig-stackdriver-bridge
+```
+
+### Using values.yaml
+
+The `values.yaml` file specifies the values for the Sysdig Stackdriver Bridge configuration parameters.  You can add the configuration to the `values.yaml` file, then use it in the `helm install` command.
+
+```bash
+$ helm install --name my-release -f values.yaml sysdiglabs/sysdig-stackdriver-bridge
+```
+
+## Configuration Parameters

 The following table lists the configurable parameters of the Sysdig Stackdriver Bridge chart and their default values.
