# Build Configuration

> Install additional software into your application's build image.

## Introduction

Private Cloud customers may install additional software, known as add-ons, into their application's build image beyond Laravel Cloud's supported PHP extensions. Add-ons are useful when your application depends on a PHP extension or other system-level software, such as media processing libraries or monitoring agents, that is not included in the default build image.

<Note>
  Build add-ons must be enabled for your organization by Laravel. If you do not see the "Build configuration" section in your environment's settings, [contact support](/support) to request access.
</Note>

## Managing add-ons

Add-ons are configured per environment. The add-ons available to your organization are determined by Laravel and shown in the "Add-ons" selector.

<Steps>
  <Step title="Open the environment's settings">
    Navigate to "Environment > Settings > General" and find the "Build configuration" section.
  </Step>

  <Step title="Select your add-ons">
    Open the "Add-ons" selector and choose the add-ons your application needs. The available options are scoped to your organization.
  </Step>

  <Step title="Save and redeploy">
    Save your changes and trigger a new deployment. Like PHP version and extension changes, add-ons are baked into a freshly built image, so changes only take effect after the environment is redeployed.
  </Step>
</Steps>

The first deployment that includes a new add-on may take longer than usual while Laravel Cloud builds and caches the updated build image. Subsequent deployments will use the cached image.

Once deployed, you may confirm a PHP extension add-on is loaded by running `php -m` from the environment's "Commands" tab.
