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 sections of a file on a pull request's Files changed tab in the form of individual line comments or as part of a pull request review. Adding line comments is a great way to discuss questions about implementation or provide feedback to the author.
For more information on adding line 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 comment, you'll need to navigate to the comment on either the Conversation tab or Files changed tab and add an additional line comment below it.
- Under your repository name, click Pull requests.
- In the list of pull requests, click the pull request where you'd like to leave line comments.
- On the pull request, click Files changed.
- Hover over the line of code where you'd like to add a comment, and click the blue comment icon.
- In the comment field, type your comment.
- Optionally, to suggest a specific change to the line, click , then edit the text within the suggestion block.
- When you're done, click Add single comment.
Anyone watching the pull request or repository will receive a notification of your comment.
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 "Opening an issue from a comment."
