After you open a pull request in a repository, collaborators or team members can comment on the comparison of files between the two specified branches, or leave general comments on the project as a whole.

You can comment on a pull request's Conversation tab to leave general comments, questions, or props.

Pull Request conversation

You can also comment on specific sections of a file on a pull request's Files changed tab. Adding line comments is a great way to discuss questions about implementation, or provide feedback to the author. You can reply directly to a line comment from the Files changed tab.

Tips:

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