+### Rails Logging Variables
+
+By default chatwoot will capture `info` level logs in production. Ref [rails docs](https://guides.rubyonrails.org/debugging_rails_applications.html#log-levels) for the additional log level options.  
+We will also retain 1 GB of your recent logs and your last shifted log file.  
+You can fine tune these settings using the following environment variables
+
+```bash
+# possible values: 'debug', 'info', 'warn', 'error', 'fatal' and 'unknown'
+LOG_LEVEL=
+# value in megabytes
+LOG_SIZE= 1024
+```
