# Software to track score in a game of Star Realms

# by default the right buttons increment/decrement  1
# holding the select button (on the left side of the badge) and then using the right buttons increment/decrement 5

# reseting the score can be done by pressing all three buttons at once or!
# just double clicking the Bottom left Button

# Score is reset back to 50
