+Note: for Nerves setups you may need additional configuration for your display
+to work as expected. If you're using an RPI3 you may want to add an `erlinit`
+configuration so that your IEx output isn't displayed on the screen. To do so in your `config/target.exs` add:
+```
+# From: https://hexdocs.pm/nerves/1.10.5/connecting-to-a-nerves-target.html#hdmi-cable
+`config :nerves, :erlinit, ctty: "ttyAMA0"`
