## Overview

OpenDA is a shared course-material archive for Tsinghua’s Automation Department, complemented by a course wiki and discussion space. The main user workflow is to find a course, retrieve its notes, assignments, or examples, and use them for study; contributors add or update materials through pull requests or issues. The tree shows course resources rather than a unified runtime application. Course nodes below represent major areas visible in the tree; their internal navigation and the wiki implementation are not shown.
