+# DocForge: Final Specification
+
+**Version:** 1.0
+**Date:** July 10, 2025
+**Overview:** DocForge is a modular, lightweight static site generator (SSG) for building "Read the Docs"-style documentation sites. It prioritizes user simplicity: content is driven entirely by Markdown files in a `content` folder, which automatically determines page structure, titles, and sidebar links. No manual HTML, link creation, or complex setups are needed. The site is mobile-friendly, SEO-optimized, and deployable to Netlify or similar hosts.
+
+Built with Node.js (using libraries like Eleventy for templating, `marked` or `remark` for Markdown parsing, and Vanilla JS for client-side features), DocForge generates static HTML/CSS/JS files. It's extensible via plugins and config, but defaults to a minimal, fast workflow.
+
+This final spec incorporates core features, enhancements for usability and performance, and explicit user instructions. It's designed to be implemented as an open-source GitHub repo with a CLI starter kit (e.g., `npx create-docforge my-site`).
+
+## Key Features
+
+- **Markdown-Driven Content and Navigation**:
+ - Pages from `.md` files; folder structure builds the sidebar tree automatically.
+ - Supports nested sections (YAML frontmatter for overrides like titles or order).
+ - Index files (e.g., `index.md`) as section landings; alphabetical sorting with numeric prefixes for custom order.
+
+- **UI and Responsiveness**:
+ - Collapsible sidebar with expandable sections, breadcrumbs, and mobile hamburger menu.
+ - Header: Customizable logo, site title, version switcher.
+ - Footer: Links, copyright, social icons.
+ - Search: Client-side fuzzy search (Lunr.js) with highlighting; optional no-results suggestions.
+ - Page Layout: Auto-TOC from headings, right sidebar for wide screens.
+
+- **Customization**:
+ - `config.yaml` for site title, logo, themes, footer, dark mode, analytics.
+ - Shortcodes in Markdown for embeds (e.g., images, tabs, notes).
+ - Themes: CSS variables; pre-built options like "minimal".
+ - Multi-Versioning: Folder-based (e.g., `content/v1/`), with UI switcher.
+
+- **Performance and Accessibility**:
+ - Minified assets, lazy images, service workers for offline.
+ - WCAG-compliant: ARIA labels, keyboard nav, contrast checks.
+ - Incremental builds for fast dev.
+
+- **Extensibility**:
+ - Plugins for analytics, comments, API docs.
+ - Hooks for custom processing.
+ - i18n support via subfolders.
+
+- **Search and Analytics**:
+ - Advanced search with stemming.
+ - Optional metrics (e.g., Plausible integration).
+
+## Architecture
+
+1. **Generator Flow**:
+ - Scan `content/` recursively.
+ - Parse Markdown with frontmatter (`gray-matter`).
+ - Build nav JSON tree.
+ - Render pages with templates (Nunjucks).
+ - Optimize/copy assets.
+ - Output to `_site/`.
+
+2. **Tech Stack**:
+ - Node.js 18+.
+ - Dependencies: Eleventy (core), marked/remark, Lunr.js, gray-matter.
+ - Dev: Live reload with Vite or Eleventy server.
+ - No runtime deps; pure static output.
+
+3. **Modularity**:
+ - Core: Content parsing/nav generation.
+ - Plugins: Load from `plugins/` (e.g., JS modules with hooks like `onParseMarkdown`).
+
+## Folder Structure
+
+```

+
+- **Content Rules**:
+ - Max nesting: 4 levels.
+ - File names: Hyphens/underscores to spaces for titles (e.g., `quick-start.md` -> "Quick Start").
+ - Assets: Place in content subfolders; reference relatively in MD.
+
+## Configuration File (config.yaml)
+
+Example:
+
+```yaml
+site:
+ title: "DocForge Docs"
+ description: "Simple static docs."
+ logo: "/assets/logo.svg"
+ favicon: "/assets/favicon.ico"
+
+navigation:
+ search: true

+ path: "/v1"
+
+footer:
+ links:
+ - text: "GitHub"
+ url: "https://github.com"
+ social:
+ - icon: "twitter"
+ url: "https://x.com"
+ copyright: "© 2025 DocForge"
+
+theme:
+ name: "minimal"
+ primaryColor: "#007bff"
+ darkMode: true # Auto/system toggle
+
+features:
+ i18n: false # Enable for multi-lang
+ analytics:
+ provider: "plausible"
+ id: "my-site.io"
+
+plugins:
+ - "analytics" # Load from plugins/
+```
+
+- **Defaults**: Sensible fallbacks if absent.
+- **Validation**: Build-time checks.
+
+## Navigation and UI Details
+
+- **Sidebar**: Tree view, highlight active, filterable on search.
+- **Header**: Logo + Title + Search + Version Switcher + Dark Toggle.
+- **Page**: Markdown-rendered body + Auto-TOC + Edit Link (GitHub).
+- **Markdown Extensions**: GFM + Shortcodes (e.g., `{% image src="image.png" %}`, `{% note "Title" %}Content{% endnote %}` for admonitions, `{% tabs %}...{% endtabs %}`).
+- **Accessibility**: Alt text prompts, print styles.
+
+## User Instructions: Formatting and Placing Markdown
+
+To make DocForge truly user-friendly, include these instructions in the starter repo's `README.md` (which can render as a self-hosted "Getting Started" page). Emphasize simplicity: "Just write Markdown—no code required."
+
+### Placing Files and Folders
+- **Create Sections**: Use folders for top-level sections (e.g., `content/guides/`). Subfolders nest subsections (e.g., `content/guides/basics/`).
+- **Add Pages**: Place `.md` files inside folders. File name becomes the page title (e.g., `setup.md` -> "Setup"). Avoid special chars; use hyphens for spaces.
+- **Section Overviews**: Add `index.md` in a folder for its landing page (e.g., `content/guides/index.md` as "Guides" intro).
+- **Custom Ordering**: Prefix files/folders with numbers (e.g., `01-intro.md`, `02-setup.md`) for sorting; alphabetical otherwise.
+- **Assets**: Put images/PDFs in the same folder as the referencing MD file. Reference relatively: ``.
+- **Nesting Limits**: Keep to 3-4 levels max for usability; deeper may collapse in UI.
+- **Multi-Version**: Prefix folders like `content/v1/`, `content/v2/`; config enables switcher.
+- **Multi-Language (Optional)**: Use `content/en/`, `content/fr/` if `features.i18n: true`; add lang switcher.
+
+### Formatting Markdown Content
+- **Basics**: Use standard Markdown:
+ - `# Heading 1` for main titles (auto-generates page TOC).
+ - `## Subheading` for sections.
+ - `- Bullet lists` or `1. Numbered`.
+ - `**Bold**`, `_italic_`, `~~strikethrough~~`.
+ - Code: Inline `` `code` `` or blocks:
+ ```
+ ```python
+ print("Hello")
+ ```
+ ```
+ - Links: `[Text](url)` (internal: `[Link](/path)`, auto-resolved).
+ - Tables:
+ | Col1 | Col2 |
+ |------|------|
+ | Val | Val |
+- **Enhancements**:
+ - **Frontmatter**: Optional YAML at top for overrides:
+ ```
+ ---
+ title: Custom Title
+ order: 3 # Override sorting
+ description: SEO meta
+ ---
+ # Your content...
+ ```
+ - **Shortcodes**: For richer elements (no extra setup needed):
+ - Images: `{% image src="path.jpg" alt="Desc" caption="Fig 1" %}` (auto-optimizes).
+ - Notes/Warnings: `{% note "Info" %}Text{% endnote %}`, `{% warning %}Caution{% endwarning %}`.
+ - Tabs: `{% tabs %}
{% tab "Tab1" %}Content1{% endtab %}
{% tab "Tab2" %}Content2{% endtab %}
{% endtabs %}`.
+ - Accordions: `{% accordion "Section" %}Hidden content{% endaccordion %}`.
+ - **Embeds**: YouTube: `[Video](https://youtube.com/watch?v=ID)` (renders iframe).
+ - **Best Practices**:
+ - Use H1 (#) once per page for main title.
+ - Add alt text to images for accessibility.
+ - Keep paragraphs short for mobile readability.
+ - Test embeds/assets locally.
+ - For code snippets, add copy buttons via shortcode: `{% code lang="js" %}code{% endcode %}`.
+
+### Tips for Success
+- **Preview Changes**: Run `npm run dev` for live site at localhost:8080.
+- **Common Issues**: If a page doesn't show, check file extension (.md) and no duplicate names.
+- **Advanced**: For custom shortcodes, add plugins; else, stick to basics.
+
+## Build and Deployment
+
+- **Commands** (via package.json):
+ - `npm install`: Setup.
+ - `npm run dev`: Local server.
+ - `npm run build`: Generate `_site/`.
+- **Netlify**:
+ - `netlify.toml`:
+ ```toml
+ [build]
+ command = "npm run build"
+ publish = "_site"
+ ```
+ - Git push triggers deploys; previews for PRs.
+- **Other Hosts**: Upload `_site/` to GitHub Pages, Vercel, etc.
+
+## Extensibility Roadmap
+
+- **Plugins**: JS files in `plugins/` with hooks (e.g., add shortcodes, post-build tasks).
+- **Themes**: Override CSS in `assets/custom.css`.
+- **Future**: PDF export plugin, AI-assisted search suggestions.
+- **Community**: MIT license; GitHub for issues.
+
+This spec is complete and ready for implementation. Prototype core parsing first, then add features iteratively. Total est. dev time: 2-4 weeks for MVP.
