+# Changes
+
+Please provide a brief description of the changes here.
+
+## Merge Requirements
+
+For new features contributions, please make sure you have completed the following
+essential items:
+
+* [ ] `CHANGELOG.md` updated to document new feature additions
+* [ ] Appropriate documentation updates in the [docs][]
+* [ ] Appropriate Helm chart updates in the [helm-charts][]
+
+<!--
+A Pull Request that modifies instrumentation code will likely require an
+update in docs. Please make sure to update the opentelemetry.io repo with any
+docs changes.
+
+A Pull Request that modifies docker-compose.yaml, otelcol-config.yaml, or
+Grafana dashboards will likely require an update to the Demo Helm chart.
+Other changes affecting how a service is deployed will also likely require an
+update to the Demo Helm chart.
+-->
+
+Maintainers will not merge until the above have been completed. If you're unsure
+which docs need to be changed ping the
+[@open-telemetry/demo-approvers](https://github.com/orgs/open-telemetry/teams/demo-approvers).
