+## Asking a Question?
+
+Please don't file GitHub issues to ask questions! Instead use:
+* Stack Overflow: http://stackoverflow.com/questions/tagged/react-virtualized
+* The react-virtualized Slack channel: https://react-virtualized.now.sh
+
+### Do you want to request a *feature* or report a *bug*?
+
+Requesting a feature?
+
+Provide as much information as possible about your requested feature. Here are a few questions you may consider answering:
+
+* What's your use case? (Tell me about your application and what problem you're trying to solve.)
+* What interface do you have in mind? (What new properties or methods do you think might be helpful?)
+* Can you point to similar functionality with any existing libraries or components? (Working demos can be helpful.)
+
+Reporting a Bug?
+
+Please include either a failing unit test or a simple repro. You can start by forking this Code Sandbox: https://codesandbox.io/s/03qpzq1p9p?module=%2FExample.js
+
+### What is the current behavior?
+
+If the current behavior is a bug, please provide the steps to reproduce and if possible a minimal demo of the problem. Your bug will get fixed much faster if we can run your code and it doesn't have dependencies other than React and react-virtualized. Paste the link to your [Code Sandbox](https://codesandbox.io/s/03qpzq1p9p?module=%2FExample.js) below:
+
+### What is the expected behavior?
+
+### Which versions of React and react-virtualized, and which browser / OS are affected by this issue? Did this work in previous versions of react-virtualized?
+|                   |          |
+|-------------------|----------|
+| Browser           |          |

+Thanks for contributing to react-virtualized!
+
+**Before submitting a pull request,** please complete the following checklist:
+
+- [ ] The existing test suites (`npm test`) all pass
+- [ ] For any new features or bug fixes, both positive and negative test cases have been added
+- [ ] For any new features, documentation has been added
+- [ ] For any documentation changes, the text has been proofread and is clear to both experienced users and beginners.
+- [ ] Format your code with [prettier](https://github.com/prettier/prettier) (`npm run prettier`).
+- [ ] Run the [Flow](https://flowtype.org/) typechecks (`npm run typecheck`).
+
+Here is a short checklist of additional things to keep in mind before submitting:
+* Please make sure your pull request description makes it very clear what you're trying to accomplish. If it's a bug fix, please also provide a failing test case (if possible). In either case, please add additional unit test coverage for your changes. :)
+* Be sure you have notifications setup so that you'll see my code review responses. (I may ask you to make some adjustments before merging.)
