+
+A [vote](https://github.com/open-telemetry/opentelemetry-collector/blob/main/docs/rfcs/README.md#voting) has been called for RFC #XXXX following the RFC process.
+
+### Stakeholders
+
+Any person in the community may vote. Votes of the stakeholders are binding. Stakeholders are
+encouraged to consider the views from the wider community when casting their vote. As defined in the
+RFC, there are N stakeholders for this RFC divided as follows:
+
+| Stakeholders                        | As defined on date | Number of people |
+|-------------------------------------|--------------------|------------------|
+| @open-telemetry/collector-approvers | yyyy-mm-dd         | N                |
+
+<!--Add additional rows if there are additional stakeholders for the RFC-->
+
+For any stakeholder team, we consider the people that were part of the team at the time the vote is called.
+
+### Voting options
+
+| Option | Description | # Votes (stakeholders) | # Votes (total) |
+|--------|-------------|------------------------|-----------------|
+| Option 1 | Description of the option | 0 | 0 |
+
+<!--Add additional rows if there are additional options for the RFC-->
+
+### Result
+
+The vote is in progress. A minimum of X votes is required to select an option.
+
+<!--Uncomment the sentence below when the vote has been closed and the result is known.-->
+<!--The vote has been closed. X stakeholders voted out of a total of Y. **Option N** has been selected with Z votes from the stakeholders.-->
+
+### Vote process
