 ## How Can Designers Contribute?
 
 If you'd like to contribute to the design or front-end, feel free to contribute to tickets labelled [Needs Design](https://github.com/WordPress/gutenberg/issues?q=is%3Aissue+is%3Aopen+label%3A%22Needs+Design%22) or [Needs Design Feedback](https://github.com/WordPress/gutenberg/issues?q=is%3Aissue+is%3Aopen+label%3A"Needs+Design+Feedback%22). We could use your thoughtful replies, mockups, animatics, sketches, doodles. Proposed changes are best done as minimal and specific iterations on the work that precedes it so we can compare. If you use <a href="https://www.sketchapp.com/">Sketch</a>, you can grab <a href="https://cloudup.com/cMPXM8Va2cy">the source file for the mockups</a> (updated April 6th).
 
 ## Contribute to the Documentation
 
-Documentation is automatically synced from master to the [Gutenberg Documentation Website](https://wordpress.org/gutenberg/handbook/) every 15 minutes.
-
-To add a new documentation page, you'll have to create a Markdown file in the [docs](https://github.com/WordPress/gutenberg/tree/master/docs) folder and add an item to the [toc.json](/docs/toc.json).
-
-### Using links
-
-It's very likely that at some point you will want to link to other documentation pages. It's worth emphasizing that all documents can be browsed in different contexts:
-- Gutenberg Handbook
-- GitHub website
-- npm website
-
-That's why it's recommended to use absolute links without the `https://github.com/WordPress/gutenberg` part for all files which match the following patterns:
-- `/docs/*.md`
-- `/packages/*/README.md`
-- `/packages/components/src/**/README.md`
+Please see the [Documentation section](/docs/contributors/document.md) of the Contributor Handbook.
 
-This way they will be properly handled in all three aforementioned contexts.

-#### THREE: Beware of “simple,” “easy,” and “just.” 
+#### THREE: Beware of “simple,” “easy,” and “just.”
 It is not for us to decide what is simple: it’s for the user to decide. If we say something is easy and the user doesn’t have an easy experience, it undermines their trust in us and what we’re building. Same goes for “just”—many of us know to avoid “simple,” but still use “just” all the time. “Just click here.” “Just enter your username.” It’s the same thing: it implies that something will be no big deal, but we can’t know what the user will find to be a big deal.
 
 It’s also safer and more helpful to be specific. “Easy” and “simple” are shorthand for explanations that we haven’t written; whenever you see them, take a minute to think about what they’re standing in for. Maybe “It’s easy to add a block by hitting ‘enter’” really means “You can add more content to the page without taking your hands off the keyboard.” Great! Say the specific thing instead of relying on “easy.”
 
 This isn’t to say that you should banish these words from your vocabulary. You might want to write a tooltip describing how the cover image block now requires less configuration, or an email about how we’re building a tool for quick creation of custom blocks, and you could legitimately say that the cover image block has been simplified or that we’re working to make custom block creation easier—there, the terms are descriptive and relative. But be on the lookout for ways you might be using (or overusing) them to make absolute claims that something is easy or simple, and use those as opportunities to be more specific and clear.
 
 #### FOUR: Look out for “we.”
-Any time text or instructions uses “we” a lot, it means the focus of the text is on the people behind the software and not the people using the software. Sometimes that’s what you actually want—but it’s usually not. The focus should typically be on the user, what they need, and how they benefit rather than “what we did” or “what we want.”

Sometimes that’s what you actually want—but it’s usually not. The focus should typically be on the user, what they need, and how they benefit rather than “what we did” or “what we want.”
 
 We’re the only ones that care about what we did or want; the user just wants software that works. If you see a lot of “we”s, think about whether you should reframe what you’re writing to focus on the benefits to and successes of the user.

+# Documentation Contributions
+
+Documentation for Gutenberg is maintained in the `/docs/` directory in the same Gutenberg Github repository. The docs are published every 15 minutes to the [Gutenberg Handbook site](https://wordpress.org/gutenberg/handbook/).
+
+## New Document
+
+To add a new documentation page:
+
+1. Create a Markdown file in the [docs](https://github.com/WordPress/gutenberg/tree/master/docs) folder
+2. Add item to the [toc.json](https://github.com/WordPress/gutenberg/blob/master/docs/toc.json) hierarchy
+3. Update manifest.json by running `npm run docs:build`
+4. Commit manifest.json with other files updated
+
+## Using Links
+
+It's very likely that at some point you will want to link to other documentation pages. It's worth emphasizing that all documents can be browsed in different contexts:
+
+- Gutenberg Handbook
+- GitHub website
+- npm website
+
+To create links that work in all contexts, you should use absolute path links without the `https://github.com/WordPress/gutenberg` prefix. You can reference files using the following patterns:
+
+- `/docs/*.md`
+- `/packages/*/README.md`
+- `/packages/components/src/**/README.md`
+
+This way they will be properly handled in all three aforementioned contexts.
