# Quickstart: Installing, using features in GitHub, and increasing usage limits
**Note**
Amazon Q Developer for GitHub is in preview release and is subject to change.
This tutorial provides a walkthrough of the following tasks:
1. Install the Amazon Q Developer app from the GitHub Marketplace and provide access to your repositories.
1. Get started with Amazon Q Developer in an issue by adding a label for feature development, or by creating a new pull request for code review. Alternatively, you can use slash commands in issues to initiate feature development. You can also initiate additional code reviews within pull requests with a slash command.
1. (Optional) Register your Amazon Q Developer app installation with your AWS account to increase your usage limits.
## Step 1: Install Amazon Q Developer in GitHub and authorize access
You can use Amazon Q Developer in GitHub free without the need to set up an AWS account to get started. The first step to using Amazon Q Developer in GitHub is to install the app from [https://github.com/marketplace/amazon-q-developer](https://github.com/marketplace/amazon-q-developer) . During this process, you can provide Amazon Q Developer access to all your GitHub repositories or selected repositories.
**Important**
To install the Amazon Q Developer app and authorize access to GitHub repositories, you must meet the requirements for the GitHub organization. For more information, see [Requirements to install a GitHub App](https://docs.github.com/en/enterprise-cloud@latest/apps/using-github-apps/installing-a-github-app-from-a-third-party#requirements-to-install-a-github-app) and [Roles in organization](https://docs.github.com/en/organizations/managing-peoples-access-to-your-organization-with-roles/roles-in-an-organization) in the *GitHub documentation*.
**To install Amazon Q Developer and authorize access**
1. Navigate to the [Amazon Q Developer for GitHub app](https://github.com/marketplace/amazon-q-developer) page.
1. If necessary, sign in to your [https://github.com/](https://github.com/) account using your GitHub credentials.
1. Review the Amazon Q Developer app's overview and features, and then choose **Install**.
1. Do one of the following to configure access to your GitHub repositories:
1. To provide access to all current and future repositories, choose **All repositories**.
1. To provide access to specific repositories, choose **Only select repositories**, choose the **Select repositories** dropdown, and then choose a repository you want to allow to access to.
1. Choose **Install** to complete installing Amazon Q Developer in GitHub and authorizing it to access your repositories.
After installing the app in GitHub and authorizing access, you're redirected to the Amazon Q Developer overview page in GitHub. You can navigate to your GitHub repository to begin using the Amazon Q Developer features.
**Note**
If your GitHub enterprise organization has enabled IP allowlisting, you must accept the allowed IP addresses on the GitHub app. You can also choose to automatically add the IP addresses to your allow list. For more information, see [Allowing access by GitHub Apps](https://docs.github.com/en/enterprise-cloud@latest/organizations/keeping-your-organization-secure/managing-security-settings-for-your-organization/managing-allowed-ip-addresses-for-your-organization#allowing-access-by-github-apps) and [Enabling allowed IP addresses](https://docs.github.com/en/enterprise-cloud@latest/organizations/keeping-your-organization-secure/managing-security-settings-for-your-organization/managing-allowed-ip-addresses-for-your-organization#enabling-allowed-ip-addresses) in the *GitHub documentation*.
The following IP addresses are used to access your GitHub resources:
```
34.228.181.128
44.219.176.187
54.226.244.221
```
## Step 2: Using Amazon Q Developer features in GitHub
After installing the Amazon Q Developer app in GitHub and authorizing access to your repositories, you can begin using the Amazon Q Developer agents for support across the software development lifecycle from coding, testing, and deploying to troubleshooting applications. For more information, see one of the following:
**Important**
The Amazon Q Developer app attempts to automatically create the **Amazon Q development agent** label in GitHub repositories you authorize access to. If the label is not automatically created, or if it's unintentionally deleted, you can manually create it in GitHub. The label must be named as **Amazon Q development agent** in order for it to be recognized and processed as a Amazon Q Developer label. For more information, see [Creating a label](https://docs.github.com/en/issues/using-labels-and-milestones-to-track-work/managing-labels#creating-a-label) in the *GitHub documentation*.

## Step 3: Increase free usage limits and configure details
You can use Amazon Q Developer agents in GitHub for free without the need to set up an AWS account to get started. You're provided with limited invocations per month for feature development and code review. You can increase your free usage at any time by registering your Amazon Q Developer app installation with your AWS account. Registering also provides with the ability to configure details such as disabling code reviews and adding tags for searching and filtering. For more information, see [Increasing usage limits and configuring details in Amazon Q Developer console](github-register-app-install.md).
**Important**
To register the app installation in the Amazon Q Developer console, you must meet the requirements for the GitHub organization. For more information, see [Requirements to install a GitHub App](https://docs.github.com/en/enterprise-cloud@latest/apps/using-github-apps/installing-a-github-app-from-a-third-party#requirements-to-install-a-github-app) and [OAuth apps and organizations](https://docs.github.com/en/apps/oauth-apps/using-oauth-apps/authorizing-oauth-apps#oauth-apps-and-organizations) in the *GitHub documentation*.
