+## Issues and Pull Request Templates
+
+Have you ever found yourself in a situation where you're reviewing pull requests or triaging issues, but you can't understand what's happening because contributors didn't provide sufficient information? Or, have you had to close an issue or pull request because the description, screenshot, or other crucial information was missing?
+
+The good news is that you can address these problems by creating issue and pull request templates. These templates allow you to customize and standardize it to include necessary information. You can see them as guides for contributors to follow when writing an issue or pull request for your project. By creating templates, you can save time on triaging issues, reviewing pull requests, and ensuring you get all the information you need from your contributors. Additionally, future contributors can benefit from these templates by understanding the history of changes made, which can help them debug or understand the code involved.

 ## Saved Replies
 
 Sometimes, you repeatedly write the same reply to issues or pull requests. It's crucial to keep clear communication between maintainers and contributors. So, when you write all comments manually, your message will no longer be consistent, and they may be unclear. You can create saved replies when you frequently respond to issues and pull requests with the same comments.
