+# Creating Audio/Visual Content
+
+For this challenge, members present their knowledge, highlighting their achievements, and showcase their understanding by exploring video and audio mediums. They might do that by giving Lunch & Learns, creating YouTube videos, recording podcasts, or some other form of audio or video content they created that explores a coding-related concept — there's no length requirement.
+
+We believe this provides value by solidifying ideas, creating a resource for others, inviting personal growth through conversations sparked by sharing, and demonstrating their ability to talk through a concept.
+
+> [!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.
