It's hard to solve a problem when important details are missing. Now project maintainers can add templates for Issues and Pull Requests to projects, helping contributors add the right details at the start of a thread. This is the first of many improvements to Issues and Pull Requests that we're working on based on feedback from the community.
To add an Issue template to a repository create a file called ISSUE_TEMPLATE in the root directory. A file extension is optional, but Markdown files (.md) are supported. Markdown support makes it easy to add things like headings, links, @-mentions, and task lists to your templates.
Pull Request templates follows the same pattern: add a file called PULL_REQUEST_TEMPLATE to the root directory of your repository.
If you're worried about the added clutter in the root directory of your project, we also added support for a .github/ folder. You can put CONTRIBUTING.md, ISSUE_TEMPLATE.md, and PULL_REQUEST_TEMPLATE.md files in .github/ and everything will work as expected.
