<project-overview>

## What This Project Is

`edu` is an [mdbook](https://rust-lang.github.io/mdBook/)-based static site called **Vibed Learning** — a collection of self-guided courses and technical references. There is no Rust code here; all content is Markdown. The generated `book/` directory is gitignored.

## Commands

```sh
# Build the static site
mdbook build

# Serve locally with live reload (default: http://localhost:3000)

# Enter the Nix dev shell (provides mdbook + nbd)

# or automatically via direnv: cd into the directory
```

</commands>

<content-structure>

## Content Structure

- `src/SUMMARY.md` — mdbook table of contents; controls site navigation. **Every new page must be listed here.**
- `src/<page>.md` — individual course or reference pages
- `book.toml` — site title, theme (navy), and source directory

To add a new page: create `src/<name>.md`, then add it to `src/SUMMARY.md` under the appropriate section heading.
