+# Supporting information for the governance process
+
+For the governance process of the JSON Schema Project, see the primary [GOVERNANCE.MD](https://github.com/json-schema-org/community/blob/main/GOVERNANCE.md) document.
+
+This document provides supporting resources.
+
+## Workflow for voting
+
+The governance document specifies two ways to make decisions, decision making via consensus and decision making via voting.
+
+This section details the workflow of the voting process.
+(The voting process may be different to the voting process found as part of the quick consensus process.)
+
+The following is a diagram generated from a Finite State Machine created in Stately.ai.
+One output is Mermaid, which is a diagram format rendered by GitHub!
+It is not as good as viewing the Finite State Machine on Stately, which I would recommend, but it does give you an idea of what to expect.
+
+When you [view this FSM on Stately](https://stately.ai/registry/editor/embed/c53f8d7e-78fa-420e-bec7-59b8ce2471dd?machineId=140d0a50-b21c-462e-99d5-f13231127cb2), you can "run the simulation" (bottom right button) and step through the process, selecting the next action at each state.
+
+While this isn't a traditional flowchart, I feel the ability to interact with and step through the process outweighs any potential familiarity with flowchart diagrammatic representation.
