+## Test Images
+
+After creating a PR, the pipeline will build the images with the tag as the name of the build in the following format:
+- Linux: `0.0.0-{branch}-{date}-{commit}`
+- Windows: `0.0.0-{branch}-{date}-{commit}-win`
+- Config Reader: `0.0.0-{branch}-{date}-{commit}-cfg`
+- Target Allocator: `0.0.0-{branch}-{date}-{commit}-targetallocator`
+
+These values can be substituted into the [values.yaml](./otelcollector/deploy/addon-chart/azure-monitor-metrics-addon/values-template.yaml) and deployed on your cluster. Follow the instructions to deploy through the backdoor [here](./otelcollector/deploy/addon-chart/Readme.md).
