# Create a repository for your source code
<a name="get-set-up-setup-repository"></a>

Before you use Amazon CodeGuru Reviewer to create code reviews, the source code that you want to analyze must be set up in a supported repository type. CodeGuru Reviewer supports AWS CodeCommit, Bitbucket, GitHub, and GitHub Enterprise Server. If you use Bitbucket or GitHub Enterprise Server, you must also create a connection to your repository using CodeConnections. For more information, see [What are connections?](https://docs.aws.amazon.com/dtconsole/latest/userguide/welcome-connections.html) in the *AWS Developer Tools User Guide*. 

If you want to suppress recommendations from CodeGuru Reviewer, you can create and add to the root directory of your repository an `aws-codeguru-reviewer.yml` file that lists files and directories to exclude from analysis. For more information, see [Suppress recommendations](recommendation-suppression.md). 

After you know the repository type and the name of your repository, you need to create a repository association. For GitHub repositories, you can create a repository association using only the CodeGuru Reviewer console. For the other supported repository types, you can use the console, AWS CLI, or Amazon CodeGuru Reviewer SDK to create a repository association. For more information, see [Working with repository associations in Amazon CodeGuru Reviewer](working-with-repositories.md).
