+**🔄 Optional: Update Content with Dynamic IPv6 Discovery**
+
+The `update-content.sh` script can be used to regenerate content with current IPv6 addresses:
+
+```bash
+# Run to update content with current cluster IPv6 addresses
+./update-content.sh
+
+# This will:
+# 1. Discover current Mycelium IPv6 addresses
+# 2. Regenerate website content with IPv6 information
+# 3. Update the ConfigMap with new content
+# 4. Trigger pod update with new content
+```
