+## Updating the trace format and tests when adjusting the framework
+
+Some things in the test framework should stay consistent, in particular with respect to the trace format.
+When adding or modifying actions, please follow these guidelines:
+* Add a case for your action to `main.go`
+* Add a case for your action to `json_utils.go/UnmarshalMapToActionType`
+* Add a generator for your action to `action_rapid_test.go` and add the generator to `GetActionGen`
+
+If the chain state from `state.go` is modified, the `ChainStateWithProposalTypes` in `json_utils.go/MarshalJSON` should be updated.
+
+When adding a new proposal type:
+* add a case for your proposal type to `json_utils.go/UnmarshalProposalWithType`
+* add a generator for your proposal type in `state_rapid_test.go` and add it to the `GetProposalGen` function
