+```json
+{
+    "youtube": {
+        "enabled": true,
+        "update_interval": 300  // Update interval in seconds (default: 300)

+        "api_key": "YOUR_YOUTUBE_API_KEY",
+        "channel_id": "YOUR_CHANNEL_ID"

+```json
+{
+    "calendar": {
+        "enabled": true,
+        "update_interval": 300,  // Update interval in seconds (default: 300)

+
+3. On first run, the application will:
