This directory contains two generators that turn the tutorial markdown files into distributable formats:
- EPUB Builder —
build_epub.py - Static Website Builder —
build_website.py
Both treat the .md files as the single source of truth — re-run the relevant
script after editing markdown to regenerate the output.
Build an EPUB ebook from the Claude How-To markdown files.
- Organizes chapters by folder structure (01-slash-commands, 02-memory, etc.)
- Renders Mermaid diagrams as SVG images with Pele, a pinned bundle run by Node.js; CSS variables are flattened to plain colours on a white background so every EPUB reader shows them
- Caches identical diagrams so each unique diagram is rendered only once
- Generates a cover image from the project logo
- Converts internal markdown links to EPUB chapter references
- Strict error mode - fails if any diagram cannot be rendered
- Python 3.10+
- uv
- Node.js >= 20 on
PATHfor Mermaid diagram rendering. The pinned Pele bundle is downloaded on first run (network needed once), sha256-verified, and cached inscripts/.vendor-cache/pele/

- Cover image with project logo

- All markdown content converted to EPUB-compatible HTML
- Mermaid diagrams rendered as SVG images

Build fails with Pele is unavailable: Install Node.js >= 20 and make sure node is on PATH (node --version).
Pele bundle download or checksum failure: The first build downloads the pinned Pele bundle from cdn.jsdelivr.net and checks every file's sha256. Offline or behind a proxy, run one build with network access; later builds use the cache in scripts/.vendor-cache/pele/<version>/. A checksum mismatch means the download was altered or truncated: delete that folder and build again.
Missing logo: The script generates a text-only cover if claude-howto-logo.png is not found.
Generate an elegant, mobile-friendly static website from the same markdown
files used by the EPUB build. The website is the rendered view; the .md
files remain the single source of truth.
- One HTML page per markdown source — internal
.mdlinks are rewritten to the corresponding pages on the site - References to non-markdown repo files (templates, scripts, JSON) become GitHub blob URLs that open the source on github.com
- Mermaid diagrams render client-side with Pele (
pele.global.js), served from the built site (no CDN at runtime); they follow the dark mode toggle - Tailwind CSS compiled with the standalone CLI (Go binary, no Node.js) and served from the built site — responsive layout with sidebar nav, in-page TOC, dark mode toggle, and prev/next page navigation
- Inter + JetBrains Mono fonts are self-hosted alongside the CSS — no third-party requests at page load
- Mirrors the EPUB curriculum order (
01-…10-plus top-level docs) - Hostable as plain static files — designed to deploy to GitHub Pages

The repo ships a workflow at .github/workflows/pages.yml that builds the
site on every push to main (when any .md or generator file changes) and
publishes via actions/deploy-pages. Enable GitHub Pages in repo settings
with Source: GitHub Actions to activate it.
build_website.py reuses the chapter-ordering logic from build_epub.py and
ships HTML templates under scripts/website_templates/:
page.html.j2— per-page Jinja2 template with sidebar nav, TOC, prev/nexttailwind.config.js,tailwind.input.css— config + entry CSS for the Tailwind standalone CLI; the CLI scans the built HTML and producessite/assets/tailwind.csswith just the utilities actually usedsite.css— small layer of site-specific styles plus Pygments theme
The Tailwind CLI binary, Pele bundle, and font files are downloaded on
first build into scripts/.vendor-cache/ (gitignored) — see
scripts/vendor_assets.py.
Heading anchors are generated using the exact algorithm in
check_cross_references.heading_to_anchor, so #anchor links validated by
the pre-commit hook resolve correctly on the rendered site.
