+
+# Operation Imports
+
+You can import operation definitions from your API schema and render them in your Docusaurus Docs. You'll need to create an `.mdx` file and import the React Component. Read more [here about MDX in Docusaurus](https://docusaurus.io/docs/markdown-features/react).
+
+# Import Operation Model in Docs
+
+The `pointer` prop is passed on to [Redoc](https://redoc.ly/docs/resources/ref-guide/#pointer).
+
+Note that `/` is escaped as `~1`.
+
+```tsx
+import ApiOperation from '@theme/ApiOperation';
+
+<ApiOperation pointer="#/paths/~1pet/post" />;
+```
+
+### Results
+
+<ApiOperation pointer="#/paths/~1pet/post" />
+
+## Import Operation Model (with example) in Docs
+
+```tsx
+import ApiOperation from '@theme/ApiOperation';
+
+<ApiOperation example pointer="#/paths/~1pet/post" />;
+```
+
+### Results
+
+<ApiOperation example pointer="#/paths/~1pet/post" />
+
+## Importing Operation Model with multiple OpenAPI schemas
+
+If you have multiple APIs loaded with redocusaurus, then it is recommended to add `id`s to the config so that you can refer them when loading operation models.
+
+```js title="docusaurus.config.js"
+const config = {
+  presets: [
+    '@docusaurus/preset-classic',
+    [
+      'redocusaurus',
