Document a design system so people can make the right design and implementation decisions—not merely find a list of components. Start with purpose and principles, explain foundations and reusable patterns, and give each component practical guidance on when and how to use it. Keep design and code references connected, make accessibility explicit, and assign people to maintain the documentation as the system changes.
What design system documentation should do
Useful documentation answers the questions a designer, developer, or product team faces while doing real work: What is this system for? Which pattern fits this need? How should it behave? How do I implement it accessibly? What should I do when the system does not cover my case?

Documentation is the explanatory layer of the system: it describes the purpose of its foundations and components and how to apply them. As the Figma Help Center explains, documentation communicates the purpose of the system and how best to apply it. A catalog can help people locate an item; guidance helps them choose and use it well.
Organize the material in layers so readers can move from shared principles to the specific pattern or code they need.
#1 Best Overall
Principles and foundations
- Purpose and scope: Explain what the system supports, who it serves, and where its guidance applies.
- Design principles: State the criteria that guide decisions when there is no exact component or rule for a case.
- Foundations: Document color, typography, spacing, layout, tokens, naming conventions, and other shared visual or behavioral rules.
- Accessibility foundations: Set out the accessibility expectations that apply across components and patterns.
Components
Give each reusable component a page or section with enough information for someone unfamiliar with it to select, design, implement, and review it. The component checklist below covers the details to include.
Patterns and layouts
Show how components work together to support common user goals and flows. Include interaction guidance and responsive considerations; an isolated component example cannot explain every decision a complete flow requires.
Implementation and operations
Provide code and API references, framework integration notes, live examples, ownership, contribution and approval steps, a feedback channel, version or update notes, and onboarding or training resources. Link design references to their corresponding code documentation when those live in different places.

What to include on a component page
Write for a reader who has not seen the component before. Use plain language, explain necessary specialist terms, and use annotated visuals when they clarify anatomy or behavior. Figma’s documentation lesson recommends making guidance accessible from the component in the design file when the fuller documentation lives elsewhere.
- Purpose and choice: Describe what the component is for, when to use it, and when not to use it. If it is unsuitable for a case, point readers toward the appropriate pattern or explain the available alternative.
- Anatomy: Label the component’s parts and explain which are required, optional, or conditional.
- Variants and states: Show available variants and states, and explain what causes a state change. Include examples that distinguish similar options.
- Behavior: Explain interactions, validation or feedback, and responsive behavior where relevant.
- Accessibility: Document keyboard interaction, assistive-technology behavior, contrast and non-color cues where relevant, and the testing expectations for the component.
- Examples: Show realistic use, including a common misuse or edge case when that would prevent a likely mistake.
- Design and implementation references: Link to the design source, code or API details, framework notes, and a live or interactive example when available.
Meaning-based names help users choose and understand options. The Figma lesson on defining a system contrasts names such as “danger” or “primary” with raw color names or codes: a name based on meaning explains intent rather than merely describing appearance.
Where should design system documentation live?
Choose the home based on who needs each kind of information, how easily they can find it, how it fits their workflow, and who will keep it current. There is no universally best platform. A small team may get further with clear, owned guidance in its existing tools than with a custom site that nobody has time to maintain.
| Home | Works well for | Trade-off to consider |
|---|---|---|
| Figma files | Design-side foundations, annotations, component descriptions, and guidance close to the design work. | Long-form or implementation guidance may need a separate home; link to it from the relevant design component. Figma guidance |
| Storybook | Documentation alongside coded components and executable examples. Stories created during development can provide basic documentation; its Docs feature supports prose and layout, generated Autodocs pages, and custom MDX pages. Storybook documentation | Design intent and broader system principles may need links or a separate place if they are not covered by the component docs. |
| Dedicated documentation site | Organizations with multiple products, audiences, or specialized pathways that benefit from customization. | Building and maintaining a dedicated site takes resources. Figma guidance |
| Shared workspace or existing design files | Small teams that want to start with tools they already use. | Keep ownership clear and content easy to find as the material grows. Figma guidance |
Compare options by audience and discoverability, the balance of design versus code content, need for live examples, customization needs, maintenance capacity, and fit with current workflows. If design and implementation references are split across tools, link them at the component or pattern where the reader needs them.

Designers need to see intent where they make design decisions; developers need implementation guidance close to working code. Keep those views consistent by linking design-file annotations and descriptions to code examples, API or prop references, framework integration notes, and live examples. Storybook can keep coded examples with the components they describe, while design files can keep annotations close to design assets.
For teams working with an established system, look for reusable guidance before creating a new component. The CMS Design System guidance for designers organizes its material into guidelines, foundations, components, patterns, layouts, and utilities, and recommends starting with existing components and documenting gaps or deviations when the system cannot meet a need. That approach helps teams distinguish a genuine system gap from a use case already covered by an existing pattern.

Make accessibility and clear writing part of the guidance
Accessibility should be visible in component and pattern documentation, not left for readers to infer. Specify keyboard interaction, assistive-technology behavior, contrast or non-color cues where relevant, and what testing is expected. For status or other meaningful information, do not rely on color alone to communicate the distinction.
Ask people who rely on the system—including people with different accessibility needs—to review and test the guidance and examples. Use plain language, define necessary specialist terms, and choose names that communicate function where appropriate. The Figma guidance on defining a design system covers testing with a range of users and using names such as “danger” or “primary” rather than raw color labels. Confirm the applicable standard and jurisdiction with the people responsible for accessibility and legal review before stating a compliance requirement; guidance here is not jurisdiction-specific legal advice.
Capture decisions and maintain the system
Documentation loses value when it describes an old system or leaves users unsure how to improve it. Make documentation part of the system lifecycle: capture decisions as they happen, review guidance when components or patterns change, and give readers a way to flag missing or unclear material.
Best Value
- Assign ownership. Name the people or team responsible for foundations, components, patterns, and implementation references.
- Define contributions and approvals. Explain how someone proposes an addition or change, who reviews it, and how a decision is communicated.
- Update documentation alongside the system. Make the relevant guidance part of the definition of done for a new or changed component or pattern, rather than a later cleanup task.
- Collect and act on feedback. Provide a clear channel and use questions or reported gaps to improve the guidance.
- Support adoption. Keep version or update notes useful, and provide onboarding or training when readers need help applying the system.
Figma’s lesson on documentation recommends making documentation part of the definition of done for new components and patterns. Its design-system lesson also raises governance questions around updates, feedback, approval, collaboration, and training.
Capture visual examples for design system docs
For a visual example, first use the browser and the relevant design or component environment to bring the page into the state you want to document. Set the viewport and interaction state, wait for content to load, and take a screenshot. Review it against the live page before adding it to documentation; a screenshot is evidence of one state, not a substitute for behavior or accessibility guidance.

Check that the documentation works in practice
- Can a new reader find the right foundation, component, or pattern without relying on tribal knowledge?
- Does each component page explain when to use it and when not to, rather than only showing its appearance?
- Can a developer reach code and behavior guidance from the design reference, and can a designer reach the design intent from code documentation?
- Are accessibility behavior and review expectations explicit where they matter?
- Is there a named owner, a contribution route, and a plan to update the material when the system changes?
Frequently Asked Questions
How much detail should a component page have?
Enough for its intended readers to choose, design, implement, and review the component without relying on unexplained assumptions. The right level depends on the component and audience; prioritize the decisions and behaviors that affect correct use.
Should every team build a dedicated documentation website?
No. Use the simplest home that keeps the guidance findable and maintainable for your team. A dedicated site is worth considering when distinct audiences or products need specialized pathways and someone can own the ongoing upkeep.
