+# Project Guidelines — dhbern.github.io
+
+Academic website for the Digital Humanities department at the University of Bern. Built with **Quarto** and hosted on **GitHub Pages**.
+
+## Architecture
+
+- **Quarto website** (`_quarto.yml`) with listings-driven homepage
+- Content lives in `content/` with four main types: `posts/`, `events/`, `projects/`, `services/`
+- `content/intro-lecture/` is a special synced section (from external repo via GitHub Actions) — do not edit directly
+- Styling: `_brand.yml` → `custom.scss` → `styles.css` (Bootstrap + brand tokens + custom SCSS)
+- Static assets (fonts) in `assets/fonts/`
+
+## Build & Dev
+
+```bash
+npm install                  # Node deps (Prettier, git-cliff)
+uv sync                      # Python environment
+npm run check                # Lint with Prettier
+npm run format               # Auto-format with Prettier
+uv run quarto preview        # Local dev server
+uv run quarto render         # Full build → _site/
+```
+
+CI runs `npm run check` (lint) then Quarto render on every push to `main`.
+
+## Content Conventions
+
+### Folder naming
+
+- Posts: `content/posts/YYYYMMDD-short-slug/index.qmd`
+- Events: `content/events/YYYYMMDD-short-slug/index.qmd`
+- Projects: `content/projects/short-slug/index.qmd`
+- Services: `content/services/short-slug/index.qmd`
+
+### Frontmatter patterns
+
+Every content page needs `title` and `categories` for listings to work.
+
+**Post:**
+
+```yaml
+title: 'Post Title'
+author: 'Author Name'
+date: '2025.04.02'
+categories: [Post]
+```
+
+**Event:**
+
+```yaml
+title: 'Event Title'
+subtitle: 'Optional subtitle'
+event-date: '2025-04-30'
+date: '2025-04-25'
+categories: [Event]
+location: 'Room, Building, City'
+author: 'Organizer'
+```
+
+**Project:**
+
+```yaml
+title: 'Project Name'
+subtitle: 'Short description'
+image: image.png
+author:
+  - name: 'Researcher'
+    orcid: '0000-0000-0000-0000'
+categories: [Project]
+```
+
+**Service:**
+
+```yaml
+title: 'Service Name'
+author: 'Team'
+categories: [Services]
+```
+
+Note: Services category is `Services` (plural), while others are singular (`Post`, `Event`, `Project`).
+
+### Author field
+
+Can be a plain string or a structured object with `name`, `orcid`, `email`, `affiliations`, `role`.
+
+### Links
+
+Use `other-links` list for external resources:
+
+```yaml
+other-links:
+  - text: 'GitHub Repository'
+    icon: github
+    href: https://github.com/example/repo
+```
+
+## Git Conventions
+
+- **Commit messages**: Conventional Commits — `feat:`, `fix:`, `doc:`, `refactor:`, `style:`, `test:`, `chore:`, `perf:`
+- **Versioning**: SemVer. Changelog auto-generated by `git-cliff`
+- **PRs**: Require discussion before opening; need 2 approvals. See [CONTRIBUTING.md](../CONTRIBUTING.md)
+
+## Key Files
+
+| File                         | Purpose                                 |
+| ---------------------------- | --------------------------------------- |
+| `_quarto.yml`                | Site config, navbar, sidebar, listings  |
+| `_brand.yml`                 | Brand colors and typography tokens      |
+| `custom.scss`                | SCSS overrides (layout, navbar, footer) |
+| `styles.css`                 | Font-face declarations, utility classes |
+| `index.qmd`                  | Homepage with three listing sections    |
+| `content/projects/index.qmd` | Projects listing page                   |
+| `content/services/index.qmd` | Services listing page                   |
+
+## Gotchas
+
+- `content/intro-lecture/` is **synced from an external repo** — edits here will be overwritten
+- Date format varies: posts use `YYYY.MM.DD`, events use ISO `YYYY-MM-DD` for `event-date`
+- The `freeze: auto` setting caches computed outputs — delete `_freeze/` if outputs seem stale
+- Rendered site goes to `_site/` (gitignored) — do not commit build artifacts
+- Primary brand color is `#d6002b` (University of Bern red)
