+However one can also create custom board layouts. See [the Electro-Smith documentation](https://github.com/electro-smith/DaisyWiki/wiki/Pd2dsy-Guide) for more information.
+
+The custom layout can be passed on via the meta.json as such:
+
+```json
+{
+    "daisy": {
+        "board_file": <path to board.json>
+    }
+}
+```
+
+## MIDI
+
+Board files that have `OOPSY_TARGET_HAS_MIDI_INPUT` configured will automatically set up UART MIDI on the default USART1 Rx and Tx pins of the Daisy (D13/14).
+
+Additionally `usb_midi`, running on the onboard micro-usb, can be enabled separately via the meta.json
+
+```json
+{
+    "daisy": {
+        "usb_midi": true
+    }
+}
+```
+
+At the moment all midi messages will be merged between USB and UART MIDI interfaces. In the future it will likely be possible to assign additional UART pins and group them under a specific PD midi "port".
+
+## [print] object
+
+Printing to serial console can be enabled using the `debug_printing` flag in the meta.json:
+
+```json
+{
+    "daisy": {
+        "debug_printing": true
+    }
+}
+```
+
+This will increase the program size with a few kb and will disable `usb_midi` as we currently do not have composite USB device yet.
