+[DBOS CLI](../api-reference/cli.md) v0.6 adds the `dbos-openapi generate` command that generates an [OpenAPI 3.0.x](https://www.openapis.org/) definition file for a DBOS application.
 This definition file can be used to automatically generate strongly typed client code to invoke DBOS application endpoints.
 
 ### Generate OpenAPI Definition File
 
-To generate a OpenAPI definition file for a DBOS application, run the following `dbos-sdk` cli command:
+First, install `@dbos-inc/dbos-openapi` as a development dependency in your project:
+```shell
+npm install --save-dev @dbos-inc/dbos-openapi
+```
+
+To generate a OpenAPI definition file for a DBOS application, run the following `dbos-openapi` cli command:
 
 ```shell
-npx dbos-sdk openapi src/operations.ts
+npx dbos-openapi generate src/operations.ts
 ```
 
 This command takes a single required argument - the path to the DBOS application's TypeScript entrypoint file.
 For DBOS applications generated by [`dbos-sdk init`](../api-reference/cli.md#npx-dbos-sdk-init), the entrypoint will be `src/operations.ts`.
 
-The `dbos-sdk openapi` command generates an OpenAPI definition file `openapi.yaml` in the same folder as the entrypoint file.
+The `dbos-openapi generate` command generates an OpenAPI definition file `openapi.yaml` in the same folder as the entrypoint file.

 This entrypoint argument is slightly different from the [`runtimeConfig.entrypoint`](../api-reference/configuration.md#runtime) config setting.
