+            We really appreciate you taking the time to report an issue. The 
+            collaborators on this project attempt to help as many people as 
+            possible, but we're a limited number of volunteers, so it's 
+            possible this won't be addressed swiftly.
+
+
+            If you need any help, or just have general Babel or JavaScript questions, we have a 
+            vibrant [Slack community](https://babeljs.slack.com) that typically always has someone 
+            willing to help. You can sign-up [here](https://slack.babeljs.io/) for an invite."

+            This issue is missing some important information we'll need
+            to be able to reproduce this issue.
+
+
+            Please understand that we receive a high volume of issues,
+            and there are only a limited number of volunteers that help
+            maintain this project. The easier it is for us to decipher an
+            issue with the info provided, the more likely it is that we'll
+            be able to help.
+
+
+            Please make sure you have the following information documented in
+            this ticket:
+            
+            1. Your Babel configuration (typically from `.babelrc` or `babel.config.js`)
+
+            2. The current (incorrect) behavior you're seeing
+
+            3. The behavior you expect
+
+            4. A [short, self-contained example](http://sscce.org/)
+
+
+            Please provide either a link to the problem via the
+            [`repl`](https://babeljs.io/repl/), or if the `repl` is
+            insufficient, a new and minimal repository with instructions on
+            how to build/replicate the issue.
