This is a programmer-friendly flashcard. Currently there are only very basic functions. You can play around with it in the terminal.
# install dependencies
npm install
# Install terminal-card globally
npm install -g .
Then you can use the terminal-card anywhere, such as:
# add a new term
terminal-card --at [term] --ad [definition]
# play games
terminal-card --game
npm uninstall -g terminal-card
