The codecrafters command is the primary interface for interacting with the CodeCrafters platform from your terminal. It facilitates the test-driven learning approach to systems programming by managing the challenges, executing tests, and providing feedback as you build foundational tools like Git, Docker, and Redis from scratch. It automates project setup, handles testing within a sandboxed environment, and uploads your code for automated grading.

The command allows you to start, test, and submit projects, providing immediate feedback on your progress. Using the command line interface makes the user experience more similar to the normal workflow of software development, especially on the backend side.

The codecrafters command requires that you have an active CodeCrafters account and are logged in via the CLI. It may also require Docker to be installed and running for certain challenges.

The typical workflow involves first initializing a project using 'codecrafters init'. Then, you iteratively develop your solution and test it using 'codecrafters test'. Once you are satisfied with your solution, you submit it using 'codecrafters submit'. The platform then grades your solution automatically.

The codecrafters CLI is typically installed via a package manager (e.g., npm, pip) or by downloading a pre-built binary from the CodeCrafters website.
