 ## Project Structure
 
-Ionic's documentation is built using [Stencil](https://stenciljs.com). The content is written as Markdown or pulled in as JSON data from other Ionic repositories.
-
-At a high level, the production documentation works like this:
-
-1. At build time, the `build-pages` script reads the Markdown in `src/pages/` and creates a JSON representation of each page at the same path
-   ```
-   pages/
-   ├── index.json
-   └── index.md
-   ```
-2. At runtime, the `docs-page` component receives the current path (e.g. `/docs`)
-3. The `docs-page` component fetches and parses the [JSON representation](https://ionicframework.com/docs/pages/index.json) of that page
-4. The `docs-page` component renders that data using a [template](https://github.com/ionic-team/ionic-docs/tree/master/src/components/page/templates)
-
-> **Note**: most reference content (e.g. APIs, native plugins, CLI commands) is not stored as Markdown. Those pages are created using data provided by other repositories to the `build-pages` script.
+Ionic's documentation is built using [Docusaurus](https://docusaurus.io/). The content is either written or generated as Markdown.
 
 ### Directories
 
-- `scripts/` - build scripts used to generate JSON representations of each page and other data used in the docs
+- `scripts/` - build scripts used to generate markdown or json files
 - `src/` - source code and content of the docs
-  - `assets/` - static assets used on the site, like images and fonts
-  - `components/` - Stencil components used in the documentation UI
-  - `demos/` - Self-contained demos, optionally presented by pages via `demoUrl` YAML frontmatter
-  - `pages/` - Markdown content organized by route and uncommitted JSON representation of each page
-  - `styles/` - Global and page-specific styles (non-component styles)
-
-### Page Templates
-
-The [`docs-page`](https://github.com/ionic-team/ionic-docs/blob/master/src/components/page/page.tsx) component is responsible for loading and rendering page content. Page content is rendered using one of the templates exported [here](https://github.com/ionic-team/ionic-docs/blob/master/src/components/page/templates/index.ts). Pages can specify a template via the `template` key in their frontmatter, or the default template will be used.
-
-```tsx
-const Template = templates[page.template] || template.default;
-return <Template page={page} />;
-```
-
-### Menu Templates
-
-The [`docs-menu`](https://github.com/ionic-team/ionic-docs/blob/master/src/components/menu/menu.tsx) component is responsible for rendering the side menu. The menu content differs by path and is specified in [per-section templates](https://github.com/ionic-team/ionic-docs/tree/master/src/components/menu/templates).

-### Authoring Locally
-
-To edit or create content locally, you'll need to [run the development server](#development-workflow). By default, the pages are only built once while starting the server. You can rebuild the pages continuously as you edit them by concurrently running the `watch-pages` script:
-
-```sh
-$ npm run watch-pages
-```
-
-> **Note**: the `watch-pages` script won't reload the page. You will need to reload the page manually after your page is rebuilt.

-# Overwrite the ionic-docs native.json file with the new changes
-mv scripts/docs-json/plugins.json /path/to/docs/scripts/data/native.json

-
-3) Open a PR in the `ionic-docs` repo, submitting the new `native.json` file.

 ## Translation
 
 The Ionic docs have been translated into Japanese and are in the process of being translated into Chinese, French, Portuguese, and Spanish. We've chosen these languages because we believe they have the greatest number of developers where English-only documentation would be a barrier.
@@ -152,26 +88,6 @@ _Please submit translation issues to the Crowdin page and not the Ionic Docs Git
 
 The Japanese translation of the docs were built by an independent team, lead by [rdlabo](https://github.com/rdlabo) and can be found and contributed to on the [ionic-jp group's `ionic-docs` project page](https://github.com/ionic-jp/ionic-docs).
 
-### Add new pages / Updating sidebar menus
-
-When adding new pages to the docs, add a new token representing the page name to the appropriate Menu template (`src/components/menu/templates`).
-
-For example, in `src/components/menu/templates/main.tsx`:
-
-```javascript
-// 'token': 'path'
-'menu-intro-cli': '/docs/intro/cli',

+# Docs folder
+
+The `/docs` folder houses all markdown files. The page structure loosely maps to the routing on the site since paths can be changed in the frontmatter.
+
+## Versioning
+
+This folder can also contain components, assets, and whatever else is meant to be versioned when the docusaurus versioning script is run. For example, if there is a page component that is only relevant to the `layout` section in the current version of Ionic, it could be added to a `_components/` folder in `docs/layout/`. When the versioning script is run, the component will be copied to `versioned_docs/verion-{X}/layout/_components/` and there will now be a separate component in `docs/layout/_components/` that can be deleted or updated to the latest version. The same concept applies to images and other files.
+
+If components are meant to be shared across versions, they can be put in `src/components/`. If images and other served files are meant to be shared across versions they can be put in `static/`.
+
+## Auto Generated Files
+
+All markdown files in these directories are generated from [scripts](/scripts):
+
+- `docs/api/`
+- `docs/cli/commands/`
+- `docs/native/`
