-  PLEASE DON'T DELETE THIS TEMPLATE UNTIL YOU HAVE READ THE FIRST SECTION.
--->
+GitHub Issues in the `facebook/react-native` repository are used exclusively for tracking bugs in React Native.
 
-### Is this a bug report?
-
-(write your answer here)
-
-<!--
-  If you answered "Yes":
-
-    We expect that it will take you about 30 minutes to produce a high-quality bug report.
-    While this may seem like a lot, putting care into issues helps us fix them faster.
-    For bug reports, it is REQUIRED to fill the rest of this template, or the issue will be closed.
-
-  If you answered "No":
-
-    We use GitHub Issues exclusively for tracking bugs in React Native. If you're looking for help,
-    the Community page at http://facebook.github.io/react-native/help.html list various resources 
-    that should help you get started.
-
-  Now scroll below!
--->
-
-### Have you read the [Contributing Guidelines](https://facebook.github.io/react-native/docs/contributing.html)?
-
-(Write your answer here.)
-
-### Environment
-
-<!--
-  In your terminal run `react-native info` and paste its contents here. Next, specify your target platform, like this:
-
-  Environment:
-    OS:  macOS Sierra 10.12.6
-    Node:  8.4.0
-    Yarn:  0.27.5
-    npm:  5.4.0
-    Watchman:  4.7.0
-    Xcode:  Xcode 8.3.3 Build version 8E3004b
-    Android Studio:  2.3 AI-162.4069837

-  Packages: (wanted => installed)
-    react-native: 0.48.1 => 0.48.1
-    react: 16.0.0-alpha.12 => 16.0.0-alpha.12

-### Steps to Reproduce
-
-<!--
-  How would you describe your issue to someone who doesn’t know you or your project?
-  Try to write a sequence of steps that anybody can repeat to see the issue.
-  Be specific! If the bug cannot be reproduced, your issue may be closed.

-### Expected Behavior
-
-<!--
-  How did you expect your project to behave?
-  It’s fine if you’re not sure your understanding is correct.
-  Just write down what you thought would happen.
--->
-
-(Write what you thought would happen.)
-
-### Actual Behavior
-
-<!--
-  Did something go wrong?
-  Is something broken, or not behaving as you expected?
-  Describe this section in detail, and attach screenshots if possible.
-  Don't just say "it doesn't work"!
--->
-
-(Write what happened. Add screenshots!)
-
-### 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.

+GitHub Issues in the `facebook/react-native` repository are used exclusively for tracking bugs in React Native. GitHub may not be the ideal place to ask questions about using React Native, but we have compiled a list of resources that should help.
+
+### Get help with your React Native app or ask code-level questions
+
+Many members of the community use Stack Overflow to ask questions. Read through the [existing questions](http://stackoverflow.com/questions/tagged/react-native?sort=frequent) tagged with **react-native** or [ask your own](http://stackoverflow.com/questions/ask?tags=react-native)!
+
+### Talk about best practices or propose changes to React Native
+
+For longer-form conversations about React Native, we’ve set up a [discussion forum at **discuss.reactjs.org**](https://discuss.reactjs.org/t/welcome-react-native-community-group/10239). This forum is a great place for discussion about best practices and application architecture as well as the future of React Native.
+
+### Chat with React and React Native community members
+
+If you need an answer right away, check out the [Reactiflux Discord](https://discord.gg/0ZcbPKXt5bZjGY5n) community. There are usually a number of React Native experts there who can help out or point you to somewhere you might want to look.

 There are many ways to contribute to React Native, and many of them do not involve writing any code. Here's a few ideas to get started:
 
-* Simply start using React Native. Go through the [Getting Started](http://facebook.github.io/react-native/docs/getting-started.html) guide. Does everything work as expected? If not, we're always looking for improvements. Let us know by [opening an issue](http://facebook.github.io/react-native/docs/contributing.html#reporting-new-issues).
-* Look through the [open issues](https://github.com/facebook/react-native/issues). Provide workarounds, ask for clarification, or suggest labels. Help [triage issues](http://facebook.github.io/react-native/docs/contributing.html#triaging-issues-and-pull-requests).
-* If you find an issue you would like to fix, [open a pull request](http://facebook.github.io/react-native/docs/contributing.html#your-first-pull-request). Issues tagged as [_Good first issue_](https://github.com/facebook/react-native/labels/Good%20first%20issue) are a good place to get started.
-* Read through the [React Native docs](http://facebook.github.io/react-native/docs). If you find anything that is confusing or can be improved, you can make edits by clicking "Improve this page" at the bottom of most docs.

 * Browse [Stack Overflow](https://stackoverflow.com/questions/tagged/react-native) and answer questions. This will help you get familiarized with common pitfalls or misunderstandings, which can be useful when contributing updates to the documentation.
 * Take a look at the [features requested](https://react-native.canny.io/feature-requests) by others in the community and consider opening a pull request if you see something you want to work on.
