 # Contributing to React Native
 
-<!-- generated_contributing_start -->
-React Native is one of Facebook's first open source projects that is both under very active development and is also being used to ship code to everybody using Facebook's mobile apps. If you're interested in contributing to React Native, hopefully this document makes the process for contributing clear.
+React Native is one of Facebook's first open source projects that is both under very active development and is also being used to ship code to everybody on https://facebook.com. We're still working out the kinks to make contributing to this project as easy and transparent as possible, but we're not quite there yet. Hopefully this document makes the process for contributing clear and preempts some questions you may have.
 
-Core contributors to React Native meet monthly and post their meeting notes on the [React Native blog](https://facebook.github.io/react-native/blog). You can also find ad hoc discussions in the [React Native Core Contributors](https://www.facebook.com/groups/reactnativeoss/) Facebook group.
-
-## [Code of Conduct](https://code.facebook.com/codeofconduct)
+## Code of Conduct
 
 Facebook has adopted a Code of Conduct that we expect project participants to adhere to. Please read [the full text](https://code.facebook.com/codeofconduct) so that you can understand what actions will and will not be tolerated.
 
-## How to contribute
-
-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 Task`](https://github.com/facebook/react-native/labels/Good%20First%20Task) 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.
-
-Contributions are very welcome. If you think you need help planning your contribution, please hop into [#react-native](https://discord.gg/0ZcbPKXt5bZjGY5n) and let people know you're looking for a mentor.
-
-### Triaging issues and pull requests
-
-One great way you can contribute to the project without writing any code is to help triage issues and pull requests as they come in.
-
-* Ask for more information if the issue does not provide all the details required by the template.
-* Suggest [labels](https://github.com/facebook/react-native/labels) that can help categorize issues.
-* Flag issues that are stale or that should be closed.
-* Ask for test plans and review code.
-
-Adding labels, closing and reopening issues, and merging pull requests is, as you may expect, limited to a subset of contributors. Simply commenting on the issue or pull request can still go a long way towards helping us keep the number of outstanding issues under control.
-
-Once you have become an active contributor in the community, you may gain access to the Facebook GitHub Bot, allowing you to perform some of these operations yourself. You can learn more about the bot in the [maintainer's guide](docs/maintainers.html#facebook-github-bot).
-

-## Our development process
+## Our Development Process
 
 Some of the core team will be working directly on [GitHub](https://github.com/facebook/react-native). These changes will be public from the beginning. Other changesets will come via a bridge with Facebook's internal source control. This is a necessity as it allows engineers at Facebook outside of the core team to move fast and contribute from an environment they are comfortable in.
 
-When a change made on GitHub is approved, it will first be imported into Facebook's internal source control. The change will eventually sync back to GitHub as a single commit once it has passed all internal tests.
-
-### Branch organization
+## Branch Organization
 
 We will do our best to keep `master` in good shape, with tests passing at all times. But in order to move fast, we will make API changes that your application might not be compatible with. We will do our best to [communicate these changes](https://github.com/facebook/react-native/releases) and version appropriately so you can lock into a specific version if need be.

 ## Bugs
 
-We use [GitHub Issues](https://github.com/facebook/react-native/issues) for our public bugs. If you would like to report a problem, take a look around and see if someone already opened an issue about it. If you a are certain this is a new, unreported bug, you can submit a [bug report](http://facebook.github.io/react-native/docs/contributing.html#reporting-new-issues).
+#### Where to Find Known Issues
 
-If you have questions about using React Native, the [help page](http://facebook.github.io/react-native/support.html) list various resources that should help you get started.
+We are using [GitHub Issues](https://github.com/facebook/react-native/issues) for our public bugs. Before filing a new task, try to make sure your problem doesn't already exist.
 
-We also have a [place where you can request features or enhancements](https://react-native.canny.io/feature-requests). If you see anything you'd like to be implemented, vote it up and explain your use case.
+Questions and feature requests are tracked elsewhere:
 
-## Reporting new issues
+  - Have a question? [Ask on Stack Overflow](http://stackoverflow.com/questions/tagged/react-native).
+  - If you have a question regarding future plans, check out the [roadmap](https://github.com/facebook/react-native/wiki/Roadmap).
+  - Have a feature request that is not covered in the roadmap? [Add it here](https://react-native.canny.io/feature-requests).
 
-When [opening a new issue](https://github.com/facebook/react-native/issues/new), always make sure to fill out the [issue template](https://raw.githubusercontent.com/facebook/react-native/master/.github/ISSUE_TEMPLATE.md). **This step is very important!** Not doing so may result in your issue getting closed. Don't take this personally if this happens, and feel free to open a new issue once you've gathered all the information required by the template.
+#### Reporting New Issues
 
-* **One issue, one bug:** Please report a single bug per issue.
-* **Provide a Snack:** The best way to get attention on your issue is to provide a reduced test case. You can use [Snack](https://snack.expo.io/) to demonstrate the issue.
-* **Provide reproduction steps:** List all the steps necessary to reproduce the issue. Provide a Snack or upload a sample project to GitHub. The person reading your bug report should be able to follow these steps to reproduce your issue with minimal effort.
-* **Try out the latest version:** Verify that the issue can be reproduced locally by updating your project to use [React Native from `master`](http://facebook.github.io/react-native/versions.html). The bug may have already been fixed!
+The best way to get your bug fixed is to provide a reduced test case. Please provide either a [Sketch](https://sketch.expo.io/) or a public repository with a runnable example.
 
-We're not able to provide support through GitHub Issues. If you're looking for help with your code, consider asking on [Stack Overflow](http://stackoverflow.com/questions/tagged/react-native) or reaching out to the community through [other channels](https://facebook.github.io/react-native/support.html).
+Please report a single bug per issue. Always provide reproduction steps. You can use Snack in many cases to demonstrate an issue: https://snack.expo.io/. If the bug cannot be reproduced using Snack, verify that the issue can be reproduced locally by targeting the latest release candidate. Ideally, check if the issue is present in master as well.
 
-### Security bugs
+Do not forget to include sample code that reproduces the issue. Only open issues for bugs affecting either the latest stable release, or the current release candidate, or master (see http://facebook.github.io/react-native/versions.html). If it is not clear from your report that the issue can be reproduced in one of these releases, your issue will be closed.
+
+We're not able to provide support through GitHub Issues. If you're looking for help with your code, consider asking on Stack Overflow:  http://stackoverflow.com/questions/tagged/react-native
+
+#### Security Bugs
 
 Facebook has a [bounty program](https://www.facebook.com/whitehat/) for the safe disclosure of security bugs. With that in mind, please do not file public issues; go through the process outlined on that page.
 
-## Pull requests
+## How to Get in Touch
 
-### Your first pull request
+Many React Native users are active on [Stack Overflow](http://stackoverflow.com/questions/tagged/react-native).
 
-So you have decided to contribute code back to upstream by opening a pull request. You've invested a good chunk of time, and we appreciate it. We will do our best to work with you and get the PR looked at.
+If you  want to get a general sense of what React Native folks talk about, check out the [React Native Community](https://www.facebook.com/groups/react.native.community) Facebook group.
 
-Working on your first Pull Request? You can learn how from this free video series:
+There is also [an active community of React and React Native users on the Discord chat platform](https://discord.gg/0ZcbPKXt5bZjGY5n) in case you need help.
 
-[**How to Contribute to an Open Source Project on GitHub**](https://egghead.io/courses/how-to-contribute-to-an-open-source-project-on-github)
+The React Native team sends out periodical updates through the following channels:
 
-We have a list of [beginner friendly issues](https://github.com/facebook/react-native/labels/Good%20First%20Task) to help you get your feet wet in the React Native codebase and familiar with our contribution process. This is a great place to get started.
+* [Blog](https://facebook.github.io/react-native/blog/)
+* [Twitter](https://www.twitter.com/reactnative)
 
-### Proposing a change
+Core contributors to React Native meet monthly and post their meeting notes on the React Native blog. You can also find ad hoc discussions in the [React Native Core Contributors](https://www.facebook.com/groups/reactnativeoss/) Facebook group.
 
-If you would like to request a new feature or enhancement but are not yet thinking about opening a pull request, we have a [place to track feature requests](https://react-native.canny.io/feature-requests).
+## Proposing a Change
 
 If you intend to change the public API, or make any non-trivial changes to the implementation, we recommend [filing an issue](https://github.com/facebook/react-native/issues/new). This lets us reach an agreement on your proposal before you put significant effort into it.
 
 If you're only fixing a bug, it's fine to submit a pull request right away but we still recommend to file an issue detailing what you're fixing. This is helpful in case we don't accept that specific fix but want to keep track of the issue.
 
-### Sending a pull request
+## Pull Requests
+
+If you send a pull request, please do it against the master branch. We maintain stable branches for stable releases separately but we don't accept pull requests to them directly. Instead, we cherry-pick non-breaking changes from master to the latest stable version.
+
+The core team will be monitoring for pull requests. When we get one, we'll run some Facebook-specific integration tests on it first. From here, we'll need to get another person to sign off on the changes and then merge the pull request. For API changes we may need to fix internal uses, which could cause some delay. We'll do our best to provide updates and feedback throughout the process.
 
 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.

+      Object form, made available under the License, as indicated by a
+      copyright notice that is included in or attached to the work
+      (an example is provided in the Appendix below).
+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes
+      of this License, Derivative Works shall not include works that remain

+   2. Grant of Copyright License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,

+      Work and such Derivative Works in Source or Object form.
+
+   3. Grant of Patent License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,

+      (except as stated in this section) patent license to make, have made,
+      use, offer to sell, sell, import, and otherwise transfer the Work,

+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and
+
+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.
