+# Table Promotion Flow
+
+Allow starting deployment flows from previous artifacts which are perhaps multiple iterations previous.
+
+## Motivation
+
+Keptn sits in a very interesting place in the CI/CD CNCF space, where it helps by gluing many tools together
+which otherwise may have a gap. One of these gaps is visibility on environment management and deployment management
+with defined sources of artifacts and defined possible environments.
+
+## Explanation
+
+This table would be created by defining artifact sources, sources of deployment information (ex. ArgoCD), and yaml which 
+defines the possible environments and how promotion happens. Maybe this could be in Shipyard
+
+A UI ties all this together, with a table where rows are artifacts (or sets of artifacts), and columns are environments.
+You should be able to click a button to trigger either a rollback to any previous artifact, or if quality gates are green
+then promote forward into a downstream environment.
+
+### Prerequisites / Proposed solution
+
+* Source of artifacts with query to represent which ones are relevant for this project
+* Sources of deployments with information to relate with the artifacts to identify what is currently deployed in what
+environment
+
+## Open questions/Implementation details
+
+* How to store the deployment information statelessly? ArgoCD can be queried, but this is a big assumption that ArgoCD
+is being used
+* Deployment needs to be done indirectly, ex. by triggering an automation tool which modifies a GitOps repo. This somehow
+needs to be setup or else the functionality will violate GitOps
