Start with what you came to do

The pages

  • Install cin90

    Installing the cin90 CLI by hand from a release: download, verify the checksum and signature, update, and fit the push-time hook around an existing one.

  • AWS cost guardrails

    Keeping an aws-de lab inside its budget in your own AWS account: setup, spend ceilings, proving the lab, and tearing it down. Written separately for students and instructors.

  • Coaching

    What the cin90 CLI observes while you work, and what it tells you: one line at push time and a question before the habit forms.

  • Shell configuration

    How cin90 start interacts with your own shell configuration: which files it reads, what it changes for the session, and where a shell's own setup can hide your tools.

  • Autograder and /cin90 review

    What the autograder posts on a student's repository, and the command that asks it for a code review.
