 To obtain the `output.json` with a containerized execution, go into the `containerapp` directory and modify the `config.ts` as shown above. The `output.json`file should be generated in the data folder. Note: the `outputFileName` property in the `config.ts` file in the `containerapp` directory is configured to work with the container.
 
+#### Running as an API

 ### Upload your data to OpenAI
 
 The crawl will generate a file called `output.json` at the root of this project. Upload that [to OpenAI](https://platform.openai.com/docs/assistants/overview) to create your custom assistant or custom GPT.
