<summary>🪧 Tips</summary>

### Chat

There are 3 ways to chat with [CodeRabbit](https://coderabbit.ai?utm_source=oss&utm_medium=github&utm_campaign=vacanza/holidays&utm_content=2492):

- Review comments: Directly reply to a review comment made by CodeRabbit. Example:
  - `I pushed a fix in commit <commit_id>, please review it.`
  - `Generate unit testing code for this file.`
  - `Open a follow-up GitHub issue for this discussion.`
- Files and specific lines of code (under the "Files changed" tab): Tag `@coderabbitai` in a new review comment at the desired location with your query. Examples:
  - `@coderabbitai generate unit testing code for this file.`
  -	`@coderabbitai modularize this function.`
- PR comments: Tag `@coderabbitai` in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples:
  - `@coderabbitai gather interesting stats about this repository and render them as a table. Additionally, render a pie chart showing the language distribution in the codebase.`
  - `@coderabbitai read src/utils.ts and generate unit testing code.`
  - `@coderabbitai read the files in the src/scheduler package and generate a class diagram using mermaid and a README in the markdown format.`
  - `@coderabbitai help me debug CodeRabbit configuration file.`

Note: Be mindful of the bot's finite context window. It's strongly recommended to break down tasks such as reading entire modules into smaller chunks. For a focused discussion, use review comments to chat about specific files and their changes, instead of using the PR comments.

### CodeRabbit Commands (Invoked using PR comments)

- `@coderabbitai pause` to pause the reviews on a PR.
- `@coderabbitai resume` to resume the paused reviews.
- `@coderabbitai review` to trigger an incremental review. This is useful when automatic reviews are disabled for the repository.
- `@coderabbitai full review` to do a full review from scratch and review all the files again.
- `@coderabbitai summary` to regenerate the summary of the PR.
- `@coderabbitai generate docstrings` to [generate docstrings](https://docs.coderabbit.ai/finishing-touches/docstrings) for this PR.
- `@coderabbitai generate sequence diagram` to generate a sequence diagram of the changes in this PR.
- `@coderabbitai resolve` resolve all the CodeRabbit review comments.
- `@coderabbitai configuration` to show the current CodeRabbit configuration for the repository.
- `@coderabbitai help` to get help.

### Other keywords and placeholders

- Add `@coderabbitai ignore` anywhere in the PR description to prevent this PR from being reviewed.
- Add `@coderabbitai summary` to generate the high-level summary at a specific location in the PR description.
- Add `@coderabbitai` anywhere in the PR title to generate the title automatically.
