Documentation Workflow

Tool Grid

Markdown Standards

Line Length

• Line wrap at 80 characters (RECOMMENDED)
• Exceptions: URLs, code blocks, tables

Headings

• ATX-style headings MUST be used (# syntax, not underlines)
• Single H1 per document (REQUIRED)
• No skipped heading levels (SHOULD NOT skip from H2 to H4)
• Blank line before and after headings (REQUIRED)

Lists

• 4-space nesting for sub-items (REQUIRED)
• Consistent marker style within document (SHOULD)

- First item
    - Nested item (4 spaces)
- Second item

Code Blocks

• Fenced code blocks MUST specify language
• Use triple backticks, not indentation

Links and References

• Prefer reference-style links for repeated URLs
• Relative paths for internal docs (RECOMMENDED)
• Check links in CI (SHOULD)

Mermaid Diagrams

Mermaid diagrams are RECOMMENDED for version-controlled visual documentation.

• Version controlled alongside code
• No external image dependencies
• Renders in GitHub, GitLab, and most Markdown viewers

graph TD
    A[Start] --> B{Decision}
    B -->|Yes| C[Action]
    B -->|No| D[End]

Common types: flowchart, sequenceDiagram, classDiagram, erDiagram, gantt, stateDiagram-v2

Best practices:

• Keep diagrams simple (SHOULD NOT exceed 20 nodes)
• Test rendering before committing

Specification Types

RFCs (Request for Comments)

Purpose: Consensus-requiring proposals for significant changes.

# RFC-XXXX: Title

## Status
Draft | Review | Accepted | Rejected | Superseded

## Summary | ## Motivation | ## Detailed Design | ## Alternatives | ## Open Questions

ADRs (Architecture Decision Records)

Purpose: Document architectural decisions and their context.

ADRs MUST NOT be deleted, only superseded by newer ADRs.

# ADR-XXXX: Title

## Status
Proposed | Accepted | Deprecated | Superseded by ADR-YYYY

## Context | ## Decision | ## Consequences

Location: docs/adr/ or docs/architecture/decisions/

Design Docs

Purpose: Implementation blueprints for features or systems.

Sections: Overview, Background, Technical Design, Security Considerations, Testing Strategy, Rollout Plan.

YAML Frontmatter

Metadata SHOULD be included in YAML frontmatter:

---
title: Document Title
author: Name
date: 2025-01-15
status: draft | review | published
tags: [api, architecture]
---

Cross-References and Linking

Internal Links

• Use relative paths from document location
• Link to specific headings with anchors

See [Installation](./docs/install.md#prerequisites)

External Links

• HTTPS URLs only (REQUIRED)
• Consider link permanence (prefer official docs over blog posts)

Anchor Generation (GitHub/GitLab)

Lowercase, spaces become hyphens, remove punctuation except hyphens. Example: ## API Design Patterns becomes #api-design-patterns

CI Validation

Documentation SHOULD be validated in CI pipelines.

# .github/workflows/docs.yml
name: Docs
on: [push, pull_request]
jobs:
  lint:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4
      - run: npx markdownlint-cli2 "**/*.md"
      - run: npx markdown-link-check README.md

Configuration (.markdownlint.json):

{ "default": true, "MD013": { "line_length": 80 }, "MD033": false }

README Structure

Project README files SHOULD follow this structure:

1. Title - Project name
2. Badges - Build status, coverage, license (OPTIONAL)
3. Description - One-line summary
4. Installation - Prerequisites and install commands
5. Usage - Quick start examples
6. Documentation - Links to detailed docs
7. Contributing - Link to CONTRIBUTING.md
8. License - License type and link
