The GitHub PullRequest Template Selector is a Chrome extension designed to enhance the Pull Request creation process on GitHub. This free add-on allows users to select from multiple templates when submitting a Pull Request, streamlining workflow and improving efficiency. It does not require any token for usage, making it accessible for all users without added complexity.

To use this extension, users simply need to install it, click the extension icon, or select 'Options' from the menu. From there, they can input the repository name and the template name to save their settings. It's important to note that users must create markdown files for their templates in the specified directory within their repository prior to using the extension. This setup ensures a structured approach to managing Pull Requests.
