Stable Baseline

Documents

Documents Overview

Stable Baseline documents are rich, structured files that combine Markdown with embedded diagrams, images, data visualizations, and AI-powered editing — all inside a collaborative, versioned workspace.

More Than Markdown

Every document in Stable Baseline is written in CDMD (CloudDocs Markdown) — an extended Markdown format that supports everything you'd expect from a modern documentation platform:

Rich Text

  • •Headings, lists, tables
  • •Bold, italic, strikethrough
  • •Colored text & highlights
  • •Keyboard shortcut badges

Code & Data

  • •Fenced code blocks with syntax highlighting
  • •Inline code
  • •Data tables
  • •Vega/Vega-Lite chart attachments

Visual Content

  • •37 diagram types (Mermaid, PlantUML, BPMN, D2, …)
  • •Embedded images (PNG, SVG, WebP, …)
  • •Captioned & aligned media
  • •Architecture diagrams with icons

Structure

  • •Callout panels (info, warning, tip, …)
  • •YAML frontmatter
  • •Version history
  • •Line-based collaborative editing

The Editor Experience

Documents open in a split-view editor with a live preview pane that renders your CDMD in real time. The editor provides:

  • →Inline toolbar — select text to see formatting options (bold, italic, heading, list, code, link, colored highlight).
  • →Diagram insertion — click the diagram button to add any of 37 diagram types. A modal guides you through selecting a type and writing (or AI-generating) the DSL.
  • →Image upload — drag & drop or click to upload images up to 10 MB. They are stored, served via CDN, and embedded with captions.
  • →Version history — every save creates a version with a change summary. You can view, compare, and restore any previous version.

What Can You Document?

Documents are designed for technical and business documentation. Common use cases include:

▸
System Architecture — C4 context/container/component diagrams, deployment topologies, infrastructure layouts.
▸
API Documentation — Endpoint references, request/response examples, authentication guides.
▸
Business Processes — BPMN process flows, decision models, swimlane diagrams.
▸
Database Schemas — ERD diagrams (Mermaid or DBML), migration guides, data dictionaries.
▸
Runbooks & Playbooks — Step-by-step operational procedures with decision trees and flowcharts.
▸
Product Requirements — PRDs, user stories, requirement traceability matrices.
▸
Knowledge Bases — Onboarding guides, FAQs, team wikis, decision logs.

37 Diagram Types

Every document supports embedded diagrams rendered from text-based DSLs. Choose the right diagram for the job — from flowcharts and ERDs to C4 architecture and waveform timing.
