 The CNCF Green Reviews Working Group (WG) is an open-source, community-led project that is part of the [CNCF Environmental Sustainability Technical Advisory Group (TAG ENV)](https://github.com/cncf/tag-env-sustainability).
 
-The aim of the Green Reviews WG is to set up infrastructure to measure the sustainability footprint of [CNCF Projects](https://www.cncf.io/projects).
+The aim of the Green Reviews WG is to set up infrastructure to measure the sustainability footprint of [CNCF Projects](https://www.cncf.io/projects). 
+
+Measuring the sustainability footprint of software is not an easy task. Our vision is that the WG will compute the sustainability data for every release of a CNCF project that requests a sustainability footprint assessment. To achieve such a vision, our goal is to develop a workflow that can integrate well with the existing software lifecycle of other CNCF projects.
+
+A good way to practically understand the first version of the workflow that the WG is designing is to take a look at the following architecture diagram:
+
+![green reviews workflow](./docs/images/workflow-vision.png)
+
+The WG’s workflow vision is that every release requesting a sustainability footprint assessment will trigger a Github Action specified in the Green Reviews repo that will start a benchmarking pipeline. The pipeline’s job is to:
+
+1. Spin up the Equinix Metal resources
+2. Install Kubernetes and all the needed observability tools
+3. Install the software that will be assessed
+4. Execute the necessary benchmark test cases
+5. Gather sustainability-related metrics
+6. Publish sustainability metrics
