+
+
+            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

+            insufficient, a new and minimal repository with instructions on
