+Default Value: `1` (`ERROR`)
 
 ## Description
-Please fill me with an explanation and useful links
+Define the log level for the logging to the SD-Card.
 
+Available options:
+
+- `1`: `ERROR`
+- `2`: `WARNING`
+- `3`: `INFO`
+- `4`: `DEBUG`
+
+As higher the level, as more log messages get written to the SD-Card.
+
+!!! Warning
+    `DEBUG` or `INFO` might damage the SD-Card if enabled long term due to excessive writes to the SD-Card!
+    A SD-Card has limited write cycles. Since the device does not support [Wear Leveling](https://en.wikipedia.org/wiki/Wear_leveling), this can wear out your SD-Card!
