# Stacked Pull Requests

PullApprove works with [GitHub stacked pull requests](https://docs.github.com/en/pull-requests/how-tos/stacked-pull-requests) without any configuration in `CODEREVIEW.toml`.

For a pull request in a stack, the `CODEREVIEW.toml` files are read from the stack's base branch (the branch the whole stack merges into) instead of the pull request's own base branch. Each pull request is still reviewed on its own diff.
