Reviewing changes in pull requests
After a pull request has been opened, you can review and discuss the set of proposed changes.
About pull request reviews
Reviews allow collaborators to comment on the changes proposed in pull requests, approve the changes, or request further changes before the pull request is merged. Repository administrators can require that all pull requests are approved before being merged.
Reviewing proposed changes in a pull request
In a pull request, you can review and discuss commits, changed files, and the differences (or "diff") between the files in the base and compare branches.
Finding changed methods and functions in a pull request
You can quickly find proposed changes to a method or function in a pull request in .go, .js, .ts, .py, .php, and .rb files.
Commenting on a pull request
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.
Viewing a pull request review
You can view all of the comments made in a single pull request review.
Approving a pull request with required reviews
If your repository requires reviews, a repository administrator or collaborator with write access must approve each pull request before it can be merged.
Dismissing a pull request review
If your repository requires reviews, you can dismiss pull request reviews that are no longer valid or are unable to be approved by the reviewer.
Checking out pull requests locally
When someone sends you a pull request from a fork or branch of your repository, you may want to merge it locally to resolve a merge conflict or to test and verify the changes on your local computer before merging on GitHub.
