+# Pretty Printing
+
+By default, Pino log lines are newline delimited JSON (NDJSON). This is perfect
+for production usage and long-term storage. It's not so great for development
+environments. Thus, Pino logs can be prettified by using a Pino prettifier
+module like [`pino-pretty`][pp]:
+
+1. Install a prettifier module as a separate dependency, e.g. `npm install pino-pretty`.
+2. Instantiate the logger with the `transport.target` option set to `'pino-pretty'`:
+  ```js
+  const pino = require('pino')
+  const logger = pino({
+    transport: {
+      target: 'pino-pretty'
+    },
+  })
+
+  logger.info('hi')
+  ```
+3. The transport option can also have an options object containing `pino-pretty` options:
+  ```js
+  const pino = require('pino')
+  const logger = pino({
+    transport: {
+      target: 'pino-pretty',
+      options: {
+        colorize: true
+      }
+    }
+  })
+
+  logger.info('hi')
+  ```
