## Overview

g-13 is a community-built UGM Computer Science course guide. Its main workflow is to select a curriculum, explore/search courses and prerequisite links, inspect course details, and optionally plan a semester roadmap. The README also identifies exam archives, alumni, learning resources, FAQ, and Indonesian/English support. Edges below are limited to README statements or relationships visible in the supplied source index/excerpts; unsampled feature internals are represented without guessed call chains.

Main entry points: [`apps/web/src/features/curriculum/useCurriculumExplorer.ts`](https://github.com/kevinantoniowiyonolauw/g-13/blob/main/apps/web/src/features/curriculum/useCurriculumExplorer.ts) (Curriculum explorer), [`packages/curriculum/src/registry.ts`](https://github.com/kevinantoniowiyonolauw/g-13/blob/main/packages/curriculum/src/registry.ts) (Curriculum registry), [`packages/curriculum/src/curricula/2026/index.ts`](https://github.com/kevinantoniowiyonolauw/g-13/blob/main/packages/curriculum/src/curricula/2026/index.ts) (2026 curriculum), [`apps/web/src/features/curriculum/components/CurriculumMap.tsx`](https://github.com/kevinantoniowiyonolauw/g-13/blob/main/apps/web/src/features/curriculum/components/CurriculumMap.tsx) (Curriculum map)
