+You might also want to keep log from previous runs, all you need to do is tell better-logging where you want to store the logs:
+
+```js
+require('better-logging')(console, {
+  saveToFile: `${Date.now()}.log`,
+});
+
+console.logLevel = 3;
+
+console.debug('foo'); // won't log to console, but will be saved in 1594897100267.log
+console.log('foo'); //     logged to console & saved in 1594897100267.log
+console.info('foo'); //    logged to console & saved in 1594897100267.log
+console.warn('foo'); //  logged to console & saved in 1594897100267.log
+console.error('foo'); //  logged to console & saved in 1594897100267.log
+console.line('foo'); //    logged to console, but "line" is never saved in logs
+```

 Some times the default log levels might not fit your needs, in those cases you can redefine the log levels to anything you like.
