 It is possible to validate the docs before bundling them with the following
 command in the `x-pack/plugins/actions/docs/openapi/` folder:
 
-  ```
-    npx swagger-cli validate entrypoint.yaml
-  ```
+```
+npx swagger-cli validate entrypoint.yaml
+npx swagger-cli validate entrypoint_serverless.yaml
+```
 
 Then you can generate the `bundled` files by running the following commands:
 
-  ```
-    npx @redocly/cli bundle entrypoint.yaml --output bundled.yaml --ext yaml
-    npx @redocly/cli bundle entrypoint.yaml --output bundled.json --ext json
-  ```
+```
+npx @redocly/cli bundle entrypoint.yaml --output bundled.yaml --ext yaml
+npx @redocly/cli bundle entrypoint.yaml --output bundled.json --ext json
+npx @redocly/cli bundle entrypoint_serverless.yaml --output bundled_serverless.yaml --ext yaml
+npx @redocly/cli bundle entrypoint_serverless.yaml --output bundled_serverless.json --ext json
+```
 
 You can run additional linting with the following command:
 
-  ```
-     npx @redocly/cli lint bundled.json
-  ```
+```
+npx @redocly/cli lint bundled.json
+npx @redocly/cli lint bundled_serverless.json
+```
