# Updating a pull request
<a name="pull-requests-update"></a>

You can make it easier for other project members to review code by updating the pull request. You can update a pull request to change its reviewers, its links to issues, the title of the pull request, or its description. For example, you might want to change the required reviewers for a pull request to remove someone who's away on vacation, and add someone else. You can also update a pull request with further code changes by pushing commits to the source branch of an open pull request. Each push to the source branch of a pull request in the CodeCatalyst source repository creates a revision. Project members can view the differences between revisions in a pull request.<a name="pull-requests-update-reviewers"></a>

**To update the reviewers for a pull request**

1. Navigate to the project where you want to update the reviewers of a pull request.

1. On the project page, under **Open pull requests**, choose the pull request where you want to update reviewers. Alternatively, in the navigation pane, choose **Code**, choose **Pull requests**, and then choose the pull request you want to update. 

1. (Optional) In **Overview**, in the **Pull request details** area, choose the plus sign to add required or optional reviewers. Choose the **X** next to a reviewer to remove them as an optional or required reviewer.

   

1. (Optional) In **Overview**, in the **Pull request details** area, choose **Link issues** to link an issue to the pull request, and then either choose an issue from the list or enter its ID. To unlink an issue, choose the unlink icon next to the issue you want to unlink. <a name="pull-requests-update-code"></a>

**To update files and code in the source branch of a pull request**

1. To update multiple files, either [create a Dev Environment](devenvironment-create.md), or clone the repository and its source branch and use a Git client or an integrated development environment (IDE) to make changes to the files in the source branch. Commit and push the changes to the source branch in the CodeCatalyst source repository to automatically update the pull request with the changes. For more information, see [Cloning a source repository](source-repositories-clone.md) and [Understanding changes in source code with commits in Amazon CodeCatalyst](source-commits.md).

1. To update an individual file in a source branch, you can use a Git client or IDE as you would for multiple files. You can also edit it directly in the CodeCatalyst console. For more information, see [Editing a file](source-files-edit.md).<a name="pull-requests-update-pull-request"></a>

**To update the title and description of a pull request**

1. Navigate to the project where you want to update the title or description of a pull request.

1. The project page displays open pull requests, including information about who created the pull request, what repository contains the branches for the pull request, and when the pull request was created. You can filter the open pull request view by source repository. Choose the pull request that you want to change from the list.

1. To view all pull requests, choose **View all**. Alternatively, in the navigation pane, choose **Code**, and then choose **Pull requests**. Use the filter box or sort functions to find the pull request you want to change, and then choose it.

1.  In **Overview**, choose **Edit**.

1. Change the title or description, and then choose **Save**.
