Valid additional arguments for all commands above:

      --config-file string   						# Allows you to choose a custom configuration file
      --format string  								  # Lets you choose the format to output logs
      --log-file string   							# Lets you choose where the logs are stored

Example of simple use: 

# To connect new indexes download

arduino-cli core update-index

# To list all connected boards

arduino-cli board list

# To install a core, an example with samd but you can do it with avr (to know how to look at the FQBN of the card)

arduino-cli core install arduino:samd

# To see the installed cores

 arduino-cli core list

# To compile

arduino-cli compile --fqbn "FQBN of the card" "file name"
arduino-cli compile --fqbn arduino:samd:mkr1000 MyFirstSketch   # Example

# To upload

arduino-cli upload -p/dev/ttyACM0 --fqbn "FQBN of the card" "file name"
