+## Logging
+
+Parse Server will, by default, will log:
+* to the console
+* daily rotating files as new line delimited JSON
+
+Logs are also be viewable in Parse Dashboard.
+
+**Want to log each request and response?** Set the `VERBOSE` environment variable when starting `parse-server`. Usage :-  `VERBOSE='1' parse-server --appId APPLICATION_ID --masterKey MASTER_KEY`
+
+**Want logs to be in placed in other folder?** Pass the `PARSE_SERVER_LOGS_FOLDER` environment variable when starting `parse-server`. Usage :-  `PARSE_SERVER_LOGS_FOLDER='<path-to-logs-folder>' parse-server --appId APPLICATION_ID --masterKey MASTER_KEY`
+
+**Want new line delimited JSON error logs (for consumption by CloudWatch, Google Cloud Logging, etc.)?** Pass the `JSON_LOGS` environment variable when starting `parse-server`. Usage :-  `JSON_LOGS='1' parse-server --appId APPLICATION_ID --masterKey MASTER_KEY`

 # Documentation
 
 The full documentation for Parse Server is available in the [wiki](https://github.com/ParsePlatform/parse-server/wiki). The [Parse Server guide](https://github.com/ParsePlatform/parse-server/wiki/Parse-Server-Guide) is a good place to get started. If you're interested in developing for Parse Server, the [Development guide](https://github.com/ParsePlatform/parse-server/wiki/Development-Guide) will help you get set up.
