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.
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.
