+## Adjusting Log Output
+The log output can be adjusted while deploying through Helm by using the `LOG_LEVEL` and/or `LOG_FORMAT` environment variables. 
+
+For example, to set the log level to `trace` the following flag can be added to the helm command:
+
+```
+    --set 'kubecostModel.extraEnv[0].name=LOG_LEVEL,kubecostModel.extraEnv[0].value=trace'
+```
+`LOG_FORMAT` options:
+
+`JSON` - A structured logging output: `{"level":"info","time":"2006-01-02T15:04:05.999999999Z07:00","message":"Starting cost-model (git commit \"1.91.0-rc.0\")"}`
+
+`pretty` - A nice human readable output: `2006-01-02T15:04:05.999999999Z07:00 INF Starting cost-model (git commit "1.91.0-rc.0")`
