+### Reproducible Demo
+
+<!--
+  Please share a project that reproduces the issue.
+  There are two ways to do it:
+
+    * Create a new app using https://snack.expo.io/ and try to reproduce the issue in it.
+      This is useful if you roughly know where the problem is, or can’t share the real code.
+
+    * Or, copy your app and remove things until you’re left with the minimal reproducible demo.
+      This is useful for finding the root cause. You may then optionally create a Snack.
+
+  This is a good guide to creating bug demos: https://stackoverflow.com/help/mcve
+  Once you’re done, copy and paste the link to the Snack or a public GitHub repository below:

+
+(Paste the link to an example project and exact instructions to reproduce the issue.)
+
+<!--
+  What happens if you skip this step?
+
+  Someone will read your bug report, and maybe will be able to help you,
+  but it’s unlikely that it will get much attention from the team. Eventually,
+  the issue will likely get closed in favor of issues that have reproducible demos.
+
+  Please remember that:
+
+    * Issues without reproducible demos have a very low priority.
+    * The person fixing the bug would have to do that anyway. Please be respectful of their time.
+    * You might figure out the issues yourself as you work on extracting it.

-Thanks for submitting a PR! Please read these instructions carefully:
+<!--
+Thank you for sending the PR!
 
-- [ ] Explain the **motivation** for making this change.
-- [ ] Provide a **test plan** demonstrating that the code is solid.
-- [ ] Match the **code formatting** of the rest of the codebase.
-- [ ] Target the `master` branch, NOT a "stable" branch.
+If you changed any code, please provide us with clear instructions on how you verified your changes work. In other words, a test plan is *required*. Bonus points for screenshots and videos!
 
-## Motivation (required)
+Please read the Contribution Guidelines at https://github.com/facebook/react-native/blob/master/CONTRIBUTING.md to learn more about contributing to React Native.
 
-What existing problem does the pull request solve?
-
-## Test Plan (required)
-
-A good test plan has the exact commands you ran and their output, provides screenshots or videos if the pull request changes UI or updates the website. See [What is a Test Plan?][1] to learn more.  
-
-If you have added code that should be tested, add tests.
-
-## Next Steps
-
-Sign the [CLA][2], if you haven't already.
-
-Small pull requests are much easier to review and more likely to get merged. Make sure the PR does only one thing, otherwise please split it.
-
-Make sure all **tests pass** on both [Travis][3] and [Circle CI][4]. PRs that break tests are unlikely to be merged.
