Repository maintainers can add templates in a repository to help contributors create high-quality issues and pull requests.
With issue and pull request templates, you can customize and standardize the information you'd like contributors to include when they open issues and pull requests in your repository.
When you create issue templates for your repository using the issue template builder, they'll be available for contributors to use when they open new issues in the repository.
When you add a pull request template to your repository, project contributors will automatically see the template's contents in the pull request body.
When you add a manually-created issue template to your repository, project contributors will automatically see the template's contents in the issue body.
