 ## Installing arduino-app-cli into the board
+
 This is reccomended way to test a local development version of the arduino-app-cli into a board.
- 1. Connect an [Arduino UNO Q](https://docs.arduino.cc/hardware/uno-q/) board via USB.
- 1. `task board:install` installs the current version of Arduino App CLI on the board (`adb` is needed). The password of the `arduino` username of the board is requested.
