## 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.

![Pull Request conversation](/assets/images/help/pull_requests/conversation.png)

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](/pull-requests/collaborating-with-pull-requests/reviewing-changes-in-pull-requests/about-pull-request-reviews). 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](/pull-requests/collaborating-with-pull-requests/reviewing-changes-in-pull-requests/reviewing-proposed-changes-in-a-pull-request)."

{% note %}

**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.

{% endnote %}

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.

{% tip %}

**Tips:**
- Pull request comments support the same [formatting](/categories/writing-on-github) as regular comments on {% data variables.product.product_name %}, such as @mentions, emoji, and references.
- You can add reactions to comments in pull requests in the **Files changed** tab.

{% endtip %}
