+Building:

+cd ui/assets && npm install
+cd ../ && mix phx.digest
+cd ../firmware && mix deps.get

+
+## Setting morse code
+Still have to find out how to correctly set secrets... so I have to do it manually now.

+ssh nerves.local
+```
+
+```elixir
+System.set_env("MORSE_MESSAGE", "...---...")
+```
