 Thanks for raising an issue! To help us help you, if you've found a bug please consider the following:
 
-* If you can demonstrate the bug using the interactive https://rollupjs.org/ demo, please do.
-* If that's not possible, perhaps because your bug involves plugins, we recommend creating a small repo that illustrates the problem: https://gist.github.com/Rich-Harris/88c5fc2ac6dc941b22e7996af05d70ff
-* If possible, use a config file as it's the standard, favoured approach to using Rollup: https://github.com/rollup/rollup/wiki/Command-Line-Interface#using-a-config-file

+Reproductions should be small, self-contained, correct examples – http://sscce.org. For example, if your bug isn't related to Gulp, **do not include Gulp in the repro**. (Side-note: if it *is* related to Gulp, this is the wrong issue tracker!) If possible, use a config file as it's the standard, favoured approach to using Rollup: https://github.com/rollup/rollup/wiki/Command-Line-Interface#using-a-config-file
 
 Occasionally, this won't be possible, and that's fine – we still appreciate you raising the issue. But please understand that Rollup is run by unpaid volunteers in their free time, and we will prioritise bugs that follow these instructions.
