## Documentation standards

**Keep it simple:**

- Be direct and concise; avoid unnecessary examples unless they clarify significantly different use cases
- Each section should answer: "What is this?" and "How do I use it?"
- Use bullet points for unordered lists; use numbered lists for sequential steps or when order matters

**Prefer references over repetition:**

- Link to existing files instead of duplicating content
  - Good: "See the configuration options in `_config.yml`"
  - Bad: Copying the entire YAML structure into docs
- Link to official library documentation for third-party tools
  - Example: "For Jekyll basics, see [Jekyll documentation](https://jekyllrb.com/docs/)"
- When referencing code files, use inline code formatting with backticks: `_config.yml`, `_pages/about.md`

**Point users to source code:**

- Reference well-documented configuration files rather than repeating their content
- Example: "Configure your deployment settings in `_config.yml`. For Docker deployment, see `docker-compose.yml`"
- When explaining CV features, point to both data sources: "The CV page is generated from `_data/cv.yml` (RenderCV format) or `assets/json/resume.json` (JSONResume format), which are kept in sync. A GitHub Actions workflow automatically generates a PDF from the RenderCV data."

**Avoid UI descriptions:**

- Don't draw or describe visual UI elements with Markdown
- Don't document button locations, menu items, or visual layouts that may change
- Focus on conceptual understanding and file-based configuration
- Good: "Enable dark mode by setting `enable_darkmode: true` in `_config.yml`"
- Bad: "Click the moon icon in the top right corner to toggle dark mode"

**Code style:**

- Use triple backticks with language identifiers for code blocks: `bash`, `yaml`, `ruby`, `liquid`, `html`
- For file paths, use inline code: `` `_config.yml` ``
- Keep code examples minimal and focused on the specific feature being explained

**Structure:**

- Use clear section headers with `##` or `###`
- Include a table of contents for longer documents (use `<!--ts-->` and `<!--te-->` markers for auto-generation)
- Group related information together
- Put important warnings or notes in blockquotes: `> Note: ...` or `> Warning: ...`

## Documentation file purposes

- `ANALYTICS.md` – Analytics and tracking configuration options
- `CONTRIBUTING.md` – Guidelines for contributors and development
- `CUSTOMIZE.md` – Comprehensive customization guide (configuration, adding content, styling, CV management, publications)
- `FAQ.md` – Frequently asked questions and common issues
- `INSTALL.md` – Installation and deployment instructions (Docker, GitHub Pages, local setup, upgrading)
- `QUICKSTART.md` – Get started in 5 minutes (repository setup, personalization, deployment)
- `README.md` – Project overview, features showcase, community examples, quick start links
- `SEO.md` – Search engine optimization guide
- `TROUBLESHOOTING.md` – Detailed troubleshooting guide for deployment, build, styling, and feature issues

## GitHub Copilot Custom Instructions

This repository includes custom instruction files to enhance GitHub Copilot's effectiveness when working with specific file types. These files are located in `.github/instructions/` and `.github/copilot-instructions.md`:

**Main Instructions:**

- `.github/copilot-instructions.md` – Repository-wide guidance including tech stack versions, Docker build process, project layout, CI/CD pipelines, common pitfalls, and file format specifications

**Path-Specific Instructions (applies to files matching specific patterns):**

- `.github/instructions/liquid-templates.instructions.md` (applies to `**/*.liquid`) – Guidance for Liquid templating, common patterns, validation, and testing
- `.github/instructions/yaml-configuration.instructions.md` (applies to `_config.yml,_data/**/*.yml`) – Guidance for YAML syntax, feature flags, BibTeX keywords, and configuration best practices
- `.github/instructions/bibtex-bibliography.instructions.md` (applies to `**/*.bib,_bibliography/**`) – Guidance for BibTeX entry syntax, custom keywords, field specifications, and publication frontmatter
- `.github/instructions/markdown-content.instructions.md` (applies to content collections) – Guidance for creating content in `_books/`, `_news/`, `_pages/`, `_posts/`, `_projects/`, and `_teachings/` with appropriate frontmatter and formatting
- `.github/instructions/javascript-scripts.instructions.md` (applies to `_scripts/**/*.js`) – Guidance for JavaScript and Liquid+JavaScript hybrid files, ES6 patterns, and script debugging

**Environment Setup:**

- `.github/workflows/copilot-setup-steps.yml` – GitHub Actions workflow that pre-configures the Copilot environment with Ruby 3.3.5, Python 3.13, Node.js, ImageMagick, and nbconvert before agent execution

These instruction files help Copilot agents understand project-specific conventions, build requirements, validation procedures, and common patterns without requiring them to explore the codebase.

## Writing style

- **Audience:** Many users are academics without coding experience; explain technical terms when you must use them
- **Tone:** Patient, encouraging, and straightforward; treat every reader as intelligent but possibly unfamiliar with web development
- **Clarity:** One concept per paragraph; use numbered lists for multi-step processes to make them easy to follow
- **Examples:** Provide real, concrete examples from the repository; show exactly what to type or where to click
- **Accessibility:** When mentioning technical terms (e.g., "YAML", "frontmatter", "repository"), briefly explain what they mean in context

## Typical tasks

1. **Update configuration documentation** when `_config.yml` changes
2. **Document new features** added to the theme (new layouts, plugins, customization options)
3. **Document CV workflow** – Explain how users choose between RenderCV and JSONResume formats, how to switch formats using frontmatter, and how optional automatic PDF generation works via GitHub Actions
4. **Clarify installation steps** when deployment methods or dependencies change
5. **Update troubleshooting** in FAQ when common issues arise
6. **Maintain consistency** across all documentation files

## Common Technical Terms & Explanations

For academics and non-technical readers, explain these terms briefly on first use:

**Web/Jekyll Terms:**

- **Jekyll** – A "static site generator" that converts your Markdown files and templates into a complete website. Think of it as a tool that takes your content and automatically formats it into web pages.
- **Frontmatter** – Metadata at the top of a file (between `---` lines) that tells Jekyll how to process the file. Example: title, date, author.
- **Liquid** – A templating language that Jekyll uses to dynamically generate pages. You'll see it in `_layouts/` and `_includes/` files with `{% %}` syntax.
- **Markdown** – A simple text format for writing content. Much easier than HTML. Files use `.md` extension.

**Configuration Terms:**

- **YAML** – A human-readable format for storing configuration data. Uses colons and indentation. Examples in `_config.yml`, `_data/` files.
- **Configuration file** – `_config.yml` contains all the settings that control how your site looks and behaves (like site title, author name, theme color).

**Content Organization:**

- **Collection** – A group of similar content items. al-folio uses collections for `_posts/` (blog posts), `_projects/`, `_news/`, etc.
- **Repository** – The folder containing all your website code and content. Stored on GitHub for version control and deployment.
- **Deployment** – The process of publishing your site so it's accessible on the internet (via GitHub Pages or other hosting).

**Publication-Related:**

- **BibTeX** – A standardized format for storing publication metadata (title, authors, year, etc.). Used in `_bibliography/papers.bib`.
- **Publication frontmatter** – Custom fields you add to BibTeX entries (like `pdf:`, `code:`, `slides:`) to add extra links and features to your publications page.

**When to explain:** If a document uses a technical term that readers might not know, briefly explain it in parentheses or a footnote the first time it appears:

```markdown
Jekyll uses **Liquid** (a templating language that generates dynamic content)
to process your files located in `_layouts/` and `_includes/`.
```

## Boundaries

- ✅ **Always do:**
  - Update documentation files (`*.md` in root directory)
  - Keep documentation in sync with actual code and configuration
  - Use existing documentation style and structure (or improve it with patterns from this agent)
  - Link to source files and official documentation
  - Test commands and instructions before documenting them
  - Explain technical terms using the common terms reference provided
  - Preserve existing table of contents markers (`<!--ts-->` and `<!--te-->`

- ⚠️ **Ask first:**
  - Major restructuring of documentation organization
  - Adding entirely new documentation files
  - Changing the documentation format or style guide
  - Removing sections that may still be relevant

- 🚫 **Never do:**
  - Modify source code files (`_layouts/`, `_includes/`, `_sass/`, etc.)
  - Edit `_config.yml` or other configuration files
  - Change GitHub Actions workflows in `.github/workflows/`
  - Modify Jekyll plugins in `_plugins/`
  - Commit without testing documentation examples
  - Delete existing documentation without replacement
  - Add executable code that runs automatically
  - Include placeholder text like "TODO" or "Coming soon" without an issue tracking it
