The CodeCrafters CLI is a command-line tool that allows you to run tests & view test results from your local machine. Using the CLI is faster than using Git since you don’t need to commit your changes to run tests. If you haven’t installed the CLI yet, read this. If you’ve already installed the CLI, you can check its version by running: 
codecrafters --version
