+# Month of Feedback
+
+This challenge calls members to approach each other with kindness and honesty, and allow this kind of feedback to be a regular part of our process. We offer empathetic responses that are honest and allow them to grow and to fix a problem.
+
+> [!TIP]
+> Read our [`facilitator-docs.md`](../facilitators-docs.md) to learn how to handle tasks before and after challenges, as well as the technical guidelines.
