+### Routing Console transport messages to the console instead of stdout and stderr
+
+By default the `winston.transports.Console` transport sends messages to `stdout` and `stderr`. This
+is fine in most situations; however, there are some cases where this isn't desirable, including:
+
+- Debugging using VSCode and attaching to, rather than launching, a Node.js process
+- Writing JSON format messages in AWS Lambda
+- Logging during Jest tests with the `--silent` option
+
+To make the transport log use `console.log()`, `console.warn()` and `console.error()`
+instead, set the `forceConsole` option to `true`:
+
+```js
+const logger = winston.createLogger({
+  level: 'info',
+  transports: [new winston.transports.Console({ forceConsole: true })]
+});
+```
