# Customize Flow Screens Using Aura Components

To customize the look and feel of your flow screen, build a custom Aura component. Configure the component and its design resource so that they’re compatible with flow screens. Then in Flow Builder, add a screen component to the screen.

- **[Configure Components for Flow Screens](/docs/platform/aura-platform/guide/components-config-for-flow-screens.md)**

  Make your custom Aura components available to flow screens in Flow Builder by implementing the `lightning:availableForFlowScreens` interface.

- **[Control Flow Navigation from an Aura Component](/docs/platform/aura-platform/guide/components-config-for-flow-screens-navigate.md)**

  By default, users navigate a flow by clicking standard buttons at the bottom of each screen. The `lightning:availableForFlowScreens` interface provides two attributes to help you fully customize your screen's navigation. To figure out which navigation actions are available for the screen, loop through the `availableActions` attribute. To programmatically trigger one of those actions, call the `navigateFlow` action from your JavaScript controller.

- **[Customize the Flow Header with an Aura Component](/docs/platform/aura-platform/guide/components-config-for-flow-screens-replace-header.md)**

  To replace the flow header with an Aura component, use the `screenHelpText` parameter from the `lightning:availableForFlowScreens` interface.

- **[Dynamically Update a Flow Screen with an Aura Component](/docs/platform/aura-platform/guide/components-config-for-flow-screens-replace-form.md)**

  To conditionally display a field on your screen, build an Aura component that uses `aura:if` to check when parts of the component should appear.
