+        Thanks for a new tool suggestion!

+        Normally, you don't need to open an issue to request support for a new tool.
+        Instead, please submit a pull request.
+        (See [DEVELOPMENT.md](https://github.com/taiki-e/install-action/blob/main/DEVELOPMENT.md) for how to add support for a new tool.)
+
+        That said, if you have any questions before getting started, or if you’re unable to contribute for any reason, feel free to open an issue.
