# About full repository analysis and incremental code reviews
<a name="repository-analysis-vs-pull-request"></a>

There are three different kinds of code reviews that CodeGuru Reviewer can do to provide recommendations.
+ *Incremental code reviews* are created automatically when you create a pull request from your repository context on an associated repository. These code reviews scan the changed code in a pull request. 
+ *Full repository analysis code reviews* are done when you create a full repository analysis code review in the CodeGuru Reviewer console. These code reviews scan all the code in a specified branch. 
**Note**  
Your first full repository analysis is created for you when you associate your repository.
+ *Full repository analysis code reviews for CI/CD workflows* scan all the source code in your CI/CD workflow. For more information, see [Create code reviews with GitHub Actions](https://docs.aws.amazon.com/codeguru/latest/reviewer-ug/working-with-cicd.html).

You can receive recommendations in code reviews by creating a full repository analysis or submitting a pull request. After you associate a repository, CodeGuru Reviewer automatically creates a full repository analysis code review, and every pull request in that repository creates an incremental code review. You can also choose to create additional full repository analysis code reviews.
