# How does W&B Launch build images?

The steps for building an image depend on the job source and the specified accelerator base image in the resource configuration.

<Note>
  When configuring a queue or submitting a job, include a base accelerator image in the queue or job resource configuration:

  ```json theme={null}
  {
      "builder": {
          "accelerator": {
              "base_image": "image-name"
          }
      }
  }
  ```
</Note>

The build process includes the following actions based on the job type and provided accelerator base image:

\| | Install Python using apt | Install Python packages | Create a user and workdir | Copy code into image | Set entrypoint | |
