# Answer questions with GitLab Duo Chat **(ULTIMATE SAAS BETA)**

> Introduced in GitLab 16.6 as a [Beta](../policy/experiment-beta-support.md#beta).

You can get AI-generated support from GitLab Duo Chat about:

- How to use GitLab.
- The contents of an issue or issue.
- The contents of a code or CI/CD configuration file.

You can also use GitLab Duo Chat to create code and CI/CD files.

When you get an answer, you can ask follow-up questions to learn more.

This is a Beta feature. We're continuously extending the capabilities and reliability of the responses.

## Ask about GitLab

You can ask questions about how GitLab works. Things like:

- `Explain the concept of a 'fork' in a concise manner.`
- `Provide step-by-step instructions on how to reset a user's password.`

## Ask about your work

You can ask about GitLab issues and epics. For example:

- `Generate a summary for the issue identified via this link: <link to your issue>`
- `Generate a concise summary of the current issue.`

## Ask about code

You can also ask GitLab Duo Chat to generate code:

- `Write a Ruby function that prints 'Hello, World!' when called.`
- `Develop a JavaScript program that simulates a two-player Tic-Tac-Toe game. Provide both game logic and user interface, if applicable.`

And you can ask GitLab Duo Chat to explain code:

- `Provide a clear explanation of the given Ruby code: def sum(a, b) a + b end. Describe what this code does and how it works.`

## Ask about CI/CD

You can ask GitLab Duo Chat to create a CI/CD configuration:

- `Create a .gitlab-ci.yml configuration file for testing and building a Ruby on Rails application in a GitLab CI/CD pipeline.`

## Ask follow up questions

You can ask follow-up questions to delve deeper into the topic or task at hand.
This helps you get more detailed and precise responses tailored to your specific needs,
whether it's for further clarification, elaboration, or additional assistance.

A follow-up to the question `Write a Ruby function that prints 'Hello, World!' when called` could be:

- `Can you also explain how I can call and execute this Ruby function in a typical Ruby environment, such as the command line?`
