Commenting on a pull request

About pull request comments

You can comment on a pull request's Conversation tab to leave general comments, questions, or props. You can also suggest changes that the author of the pull request can apply directly from your comment.

You can also comment on specific files or sections of a file in a pull request's Files changed tab in the form of individual line or file comments, or as part of a pull request review. Adding line or file comments is a great way to discuss questions about implementation or provide feedback to the author. For more information about pull request reviews, see About pull request reviews.

For more information on adding line or file comments to a pull request review, see Reviewing proposed changes in a pull request.

Note

If you reply to a pull request via email, your comment will be added on the Conversation tab and will not be part of a pull request review.

To reply to an existing line or file comment, you'll need to navigate to the comment on either the Conversation tab or Files changed tab and add an additional comment below it.

Tip

  • Pull request comments support the same formatting as regular comments on GitHub, such as @mentions, emoji, and references.
  • You can add reactions to comments in pull requests in the Files changed tab.

Resolving conversations

You can resolve a conversation in a pull request if you opened the pull request or if you have write access to the repository where the pull request was opened.

To indicate that a conversation on the Files changed tab is complete, click Resolve conversation.

The entire conversation will be collapsed and marked as resolved, making it easier to find conversations that still need to be addressed.

If the suggestion in a comment is out of your pull request's scope, you can open a new issue that tracks the feedback and links back to the original comment. For more information, see "Creating an issue."

Discovering and navigating conversations

You can discover and navigate to all the conversations in your pull request using the Conversations menu that's shown at the top of the Files Changed tab.

From this view, you can see which conversations are unresolved, resolved, and outdated. This makes it easy to discover and resolve conversations.
