+# Plugin for managing dynamic page creation in OSD
+Use this plugin to create pages that multiple plugins can contribute to. A typical use case is the OSD homepage,
+which can have contents contributed by different plugins, see the screenshot:
+
+![image](https://github.com/user-attachments/assets/501c2433-38c5-4b53-9974-de6f63eab94d)
+
+## Getting started
+### Step 1: Add `contentManagement` to `requiredPlugins`
+Ensure `contentManagement` is listed in the `requiredPlugins` array of your plugin's manifest file.
+```json
+{
+  "requiredPlugins": ["contentManagement"]
+}
+```
+
+### Step 2: Create a page with defined sections
+A section is typically a container on the page, and a page could have multiple sections. Using the homepage as an example:
+```typescript
+export const HOME_PAGE_ID = 'osd_homepage';
+export enum SECTIONS {
+  GET_STARTED = `get_started`,
+  SERVICE_CARDS = `service_cards`,
+  RECENTLY_VIEWED = `recently_viewed`,
+}
+
+export class MyPlugin implements Plugin {
+  public setup(core, { contentManagement }) {
+    contentManagement.registerPage({
+      id: HOME_PAGE_ID,
+      title: 'Home',
+      sections: [
+        {
+          id: SECTIONS.SERVICE_CARDS,
+          order: 3000,
+          kind: 'dashboard',
+        },
+        {
+          id: SECTIONS.RECENTLY_VIEWED,
+          order: 2000,
+          title: 'Recently viewed',
+          kind: 'custom',
+          render: (contents) => (
+            <>
+              {contents.map((content) => content.kind === 'custom' ? content.render() : null)}
+            </>
+          ),
+        },
+        {
+          id: SECTIONS.GET_STARTED,
+          order: 1000,
+          title: 'Define your path forward with OpenSearch',
+          kind: 'card',
+        },
+      ],
+    });
+  }
+}
+```
+Here we defined a page with three different kinds of sections: `dashboard`, `custom` and `card`, the sections will be sorted by `order` in ascending order.
+Each type of section serves a different purpose:
+
+#### `card` section
+A `card` section is one of the pre-defined section type that renders a horizontal list of OuiCard components, to add
+contents to a `card` section, call `contentManagement.registerContentProvider` with a `title` and `description`, and the content
+will be sorted by its `order` in ascending order.
+```typescript
+export class MyPlugin implements Plugin {
+  public start(core, { contentManagement }) {
+    contentManagement.registerContentProvider({
+      id: `home_get_start`, // id for the content provider, could be any unique string
+      getTargetArea: () => `${HOME_PAGE_ID}/${SECTIONS.GET_STARTED}`, // target area follow the convention: {page_id}/{section_id}
+      getContent: () => ({
+        id: 'card_content_id', // id for the content, could be any unique string
+        kind: 'card',
+        order: 1000,
+        description: 'Card description',
+        title: 'Card title'
+      }),
+    });
+  }
+}
+```
+
+#### `dashboard` section
+A `dashboard` section is typically a dashboard embeddable container, it can render visualization or dashboard by their id,
+or it can render arbitrary React components.
+
+Add a saved visualization to a `dashboard` section **statically**
+```typescript
+export class MyPlugin implements Plugin {
+  public start(core, { contentManagement }) {
+    contentManagement.registerContentProvider({
+      id: `visualization_content_provider`,
+      getTargetArea: () => `${HOME_PAGE_ID}/${SECTIONS.SERVICE_CARDS}`,
+      getContent: () => ({
+        id: 'visualization_content_id', // id for the content, could be any unique string
+        kind: 'visualization',
+        order: 1000,
+        input: {
+          kind: 'static',
+          id: 'c0ba29f0-eb8f-11ed-8e00-17d7d50cd7b2' // the visualization id
+        }
+      }),
+    });
+  }
+}
+```
+
+Add a saved visualization to a `dashboard` section **dynamically**
+```diff
+export class MyPlugin implements Plugin {
+  public start(core, { contentManagement }) {
+    contentManagement.registerContentProvider({
+      id: `visualization_content_provider`,
+      getTargetArea: () => `${HOME_PAGE_ID}/${SECTIONS.SERVICE_CARDS}`,
+      getContent: () => ({
+        id: 'visualization_content_id',
+        kind: 'visualization', // with `visualization` kind
+        order: 1000,
+        input: {
+-          kind: 'static',
+-          id: 'c0ba29f0-eb8f-11ed-8e00-17d7d50cd7b2' // the visualization id
++          kind: 'dynamic',
++          get: () => Promise.resolve('c0ba29f0-eb8f-11ed-8e00-17d7d50cd7b2') // the visualization id
+        }
+      }),
+    });
+  }
+}
+```
+
+Add a saved dashboard to a `dashboard` section **statically**
+```typescript
+export class MyPlugin implements Plugin {
+  public start(core, { contentManagement }) {
+    contentManagement.registerContentProvider({
+      id: `dashboard_content_provider`,
+      getTargetArea: () => `${HOME_PAGE_ID}/${SECTIONS.SERVICE_CARDS}`,
+      getContent: () => ({
+        id: 'dashboard_content_id',
+        kind: 'dashboard', // with `dashboard` kind
+        order: 1000,
+        input: {
+          kind: 'static',
+          id: 'c39012d0-eb7a-11ed-8e00-17d7d50cd7b2' // the saved dashboard id
+        }
+      }),
+    });
+  }
+}
+```
+
+Similarly, you can add a saved dashboard to a `dashboard` section **dynamically**
+```diff
+export class MyPlugin implements Plugin {
+  public start(core, { contentManagement }) {
+    contentManagement.registerContentProvider({
+      id: `dashboard_content_provider`,
+      getTargetArea: () => `${HOME_PAGE_ID}/${SECTIONS.SERVICE_CARDS}`,
+      getContent: () => ({
+        id: 'dashboard_content_id',
+        kind: 'dashboard', // with `dashboard` kind
+        order: 1000,
+        input: {
+-          kind: 'static',
+-          id: 'c39012d0-eb7a-11ed-8e00-17d7d50cd7b2' // the saved dashboard id
++          kind: 'dynamic',
++          get: () => Promise.resolve('c39012d0-eb7a-11ed-8e00-17d7d50cd7b2') // the saved dashboard id
+        }
+      }),
+    });
+  }
+}
+```
+
+You can also add custom components to a `dashboard` section
+```typescript
+export class MyPlugin implements Plugin {
+  public start(core, { contentManagement }) {
+    contentManagement.registerContentProvider({
+      id: `custom_content_provider`,
+      getTargetArea: () => `${HOME_PAGE_ID}/${SECTIONS.SERVICE_CARDS}`,
+      getContent: () => ({
+        id: 'custom_content_id',
+        kind: 'custom', // with `dashboard` kind
+        order: 1000,
+        render: () => <MyComponent />
+      }),
+    });
+  }
+}
+```
+
+#### `custom` section
+If the existing pre-defined sections do not meet your needs, you could use `custom` section to customize the rendering of the contents,
+a custom section is typically defined with `kind: 'custom'` and a `render` function:
+```typescript
+{
+  id: SECTIONS.RECENTLY_VIEWED,
+  order: 2000,
+  title: 'Recently viewed',
+  kind: 'custom',
+  render: (contents) => (
+    <>
+      {contents.map((content) => content.kind === 'custom' ? content.render() : null)}
+    </>
+  ),
+}
+```
+
+Now adds content to a `custom` section
+```typescript
+export class MyPlugin implements Plugin {
+  public start(core, { contentManagement }) {
+    contentManagement.registerContentProvider({
+      id: 'recent_provider_id',
+      getContent: () => {
+        return {
+          order: 1,
+          id: 'recent_content_id',
+          kind: 'custom',
+          render: () => <RecentWork />,
+        };
+      },
+      getTargetArea: () => `${HOME_PAGE_ID}/${SECTIONS.RECENTLY_VIEWED}`,
+    });
+  }
+}
+```
+
+### Step 3: Render the page
+Finally, render the page in your application:
+```typescript
+<Route exact path="/">
+  {contentManagement.renderPage(HOME_PAGE_ID)}
+</Route>
+```
