+#### Triage status
+
+To communicate the triage status with other collaborators, you can apply status
+labels to issues. These labels prevent duplicating effort.
+
+| Status                        | Description                                                                                                                                                                 |

+| status/needs-attention        | Apply this label if an issue (or PR) needs more eyes.
