## Overview

HITCS is a static, community-contributed collection of HIT computer-science course materials, not a single executable application. A student’s primary workflow is to browse the course-organized repository and use its experiments, notes, past exams, and other study resources. Contributors add or correct materials through the repository’s contribution process; the README also welcomes issues and pull requests. The tree confirms many course-specific collections, but does not establish runtime links among them. Some README-described resource types are not identifiable in the supplied tree, so they are noted without assigning unsupported paths.
