# SDK Customization

After integrating the Luciq SDK into your application, you will automatically be collecting data in the background of your app. The collected data includes the Session Profiler and other useful features that help you investigate bugs and improve the quality of your app.

However, you'll need to gather other information that requires input from your app users, such as for bug reporting, in-app surveys, and feature requests.

To make your users' experience as simple and seamless as possible, you can customize the colors of all Luciq screens, change the language, modify the messages and text that appear, change the invocation events, as well as control which popup should appear to your users and when.

The SDK Customizations section of the Luciq docs is divided into the following topics:

#### [Welcome Message](/flutter/setup-luciq-for-flutter/custom-settings/sdk-customization/welcome-message.md)

Discusses how you can on-board your users and teach them how to reach you using Luciq for either beta testers or live users.

#### [Prompt Options](/flutter/setup-luciq-for-flutter/custom-settings/sdk-customization/prompt-options.md)

Explains how to control the default menu that pops up when Luciq is invoked in your app.

#### [UI Color & Theme](/flutter/setup-luciq-for-flutter/custom-settings/sdk-customization/ui-color-and-theme.md)

Describes how to customize the SDK to match your app's design and brand palette.

#### [SDK Locale](/flutter/setup-luciq-for-flutter/custom-settings/sdk-customization/sdk-locale.md)

Explains how to change the language of the SDK as well as the content of all the messages that your users see.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.luciq.ai/flutter/setup-luciq-for-flutter/custom-settings/sdk-customization.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
