+### Scenarios and values.yaml
+
+For cases where the same job config must be run for multiple instances, a `scenarios` list can be specified in a file called `values.yaml`.
+
+For example, given a stress test package with multiple tests represented as separate files:
+
+```
+values.yaml
+templates/
+app/
+  scenarioLongRunning.js
+  scenarioPeekMessages.js
+  scenarioBatchReceive.js
+...
+```
+
+The pod command in the job manifest could be configured to run a variable file name:
+
+```
+command: ["node", "app/{{ .Scenario }}.js"]
+```
+
+In order to accomplish this, add the scenarios list to `values.yaml`
+
+```
+scenarios:
+  - scenarioLongRunning
+  - scenarioPeekMessages
+  - scenarioBatchReceive
+```
+
+The underlying `stress-test-addons` helm library will handle a scenarios list automatically, and deploy multiple instances of the stress test job, one for each scenario.
