+The `-loglevel` flag allows you to control the verbosity of the application's logging output. 
 
-0 = Panic, 1 = Fatal, 2 = Error, 3 = Warning, 4 = Info, 5 = Debug, 6 = Trace
+Acceptable values for this flag are:

-[mapname]: ./img/mapname.png
+- `trace`
+- `debug`
+- `info`
+- `warn`
+- `error`
+- `fatal`

+For example, to set the log level to `debug`, you can use:

+```bash

+The default log level is `warn` if the flag is not specified.

 This rcon client is fully compatible with the [Q3 Rcon Proxy][q3rcon-proxy] package.
