# Codebase to Course

> Skill by [ara.so](https://ara.so) — Daily 2026 Skills collection.

A Claude Code skill that turns any codebase into a beautiful, self-contained single-page HTML course. Designed for "vibe coders" — people who build with AI tools and want to understand their own codebase well enough to steer AI better, debug more effectively, and talk to engineers confidently.

## What it produces

A **single HTML file** with zero dependencies that works offline, containing:

- Scroll-based modules with progress tracking and keyboard navigation
- Code ↔ Plain English side-by-side translations using real code from the repo
- Animated visualizations — data flow, component group chats, architecture diagrams
- Interactive quizzes testing *application* ("which files change if you add favorites?"), not memorization
- Glossary tooltips on hover for every technical term
- Warm, distinctive design (not the typical purple-gradient AI aesthetic)

## Installation

### As a Claude Code skill

```bash
# Clone the repo
git clone https://github.com/zarazhangrui/codebase-to-course

# Install the skill
cp -r codebase-to-course/codebase-to-course ~/.claude/skills/

The skill folder structure after install:

~/.claude/skills/codebase-to-course/
├── SKILL.md                    # Main skill instructions Claude reads
└── references/
    ├── design-system.md        # CSS tokens, typography, colors, layout rules
    └── interactive-elements.md # Quiz, animation, visualization code patterns

Verify installation

Open any project in Claude Code and say one of the trigger phrases. Claude will read SKILL.md and the reference files before generating the course.

How to use

Basic invocation

Open a project in Claude Code and say any of:

"Turn this codebase into an interactive course"
"Teach me how this code works"
"Make a course from this project"
"Explain this codebase interactively"

Claude will:

1. Analyze the codebase structure (entry points, key files, data flow)
2. Identify the most important concepts for a vibe coder to understand
3. Generate a single course.html file in the project root
