+# CodeRabbit Configuration
+
+This document explains how CodeRabbit is configured for CUDA Python. For review
+commands and guidance, see the
+[CodeRabbit section of the contributing guide](../CONTRIBUTING.md#coderabbit).
+For complete product documentation, see the
+[CodeRabbit documentation](https://docs.coderabbit.ai/).
+
+CUDA Python configures CodeRabbit through [`.coderabbit.yaml`](../.coderabbit.yaml)
+in the repository root. For pull requests from a branch in the same repository,
+the configuration in that branch is used for the review. Pull requests from
+forks use the target branch's configuration instead, so changes to
+`.coderabbit.yaml` in a fork do not affect that review.
+
+When setting up or updating CodeRabbit:
+
+1. Keep repository-specific settings in `.coderabbit.yaml`.
+2. Use `@coderabbitai configuration` on a pull request to inspect the resolved
+   configuration. This is useful when checking whether CodeRabbit is using the
+   expected repository settings for that pull request.
+3. Use `@coderabbitai generate configuration` to export the resolved
+   configuration if a new baseline is needed. This is useful when moving
+   settings into a reviewable repository configuration file.
+4. Keep configuration changes small and reviewable.
+5. Use `reviews.path_instructions` for path-specific review guidance.
+6. Use `knowledge_base.code_guidelines.filePatterns` for CUDA Python guidance
+   files that CodeRabbit should read as review context.
+
+The CUDA Python configuration should keep comments focused on correctness, API
+stability, performance, security, and other high-impact issues. Avoid enabling
+features that add noisy generated comments or code by default.

+## CodeRabbit
+
+This section explains how to use CodeRabbit for CUDA Python pull request review.
+For complete product documentation, see the
+[CodeRabbit documentation](https://docs.coderabbit.ai/).
+
+### Review Guidance
+
+We treat CodeRabbit feedback as review assistance, not as a merge requirement by
+itself. Maintainers remain responsible for deciding whether comments are
+actionable and whether a pull request has adequate tests and CI coverage.
+
+### Pull Request Reviews
+
+Automatic reviews may be disabled or restricted by the repository
+configuration. PR authors and maintainers can request a review explicitly by
+posting a comment on the pull request:
+
+```text
+@coderabbitai review
+```
+
+Use a full review when the pull request should be reviewed again from scratch:
+
+```text
+@coderabbitai full review
+```
+
+Other useful commands:
+
+- `@coderabbitai help` shows the current command reference.
+- `@coderabbitai configuration` shows the active configuration.
+- `@coderabbitai summary` can be placed in the pull request description as a
+  placeholder for the generated summary.
+- `@coderabbitai pause` and `@coderabbitai resume` pause or resume automatic
+  review behavior. This is useful when a pull request is still being updated
+  frequently and should not be reviewed again until it is ready.
+- `@coderabbitai ignore` can be placed in the pull request description to
+  disable automatic reviews.
+
 ## Pixi lockfiles
 
 The repository checks in a `pixi.lock` next to each `pixi.toml`. Those lockfiles
