## Overview
OpenDS is a public course-materials and study-notes site for Fudan University’s School of Data Science. A student enters through the course portal, selects a course, and browses its notes and available assignments, slides, labs, or projects. The repository also includes course archives and a Mermaid diagram component. The tree and README establish the content branches; sampled source does not establish all component wiring, so uncertain links are omitted. The sync script is part of site preparation, not the product workflow.
Main entry points: [`docs/index.md`](https://github.com/hadanice/opends/blob/main/docs/index.md) (Site home), [`docs/.vitepress/components/CoursePortal.vue`](https://github.com/hadanice/opends/blob/main/docs/.vitepress/components/CoursePortal.vue) (Course portal), [`docs/courses/map.md`](https://github.com/hadanice/opends/blob/main/docs/courses/map.md) (Course map), [`docs/courses/index.md`](https://github.com/hadanice/opends/blob/main/docs/courses/index.md) (Course index)
