-# Docker Test Environment
-
-This is a high-level overview of the test configuration using Docker. 
-It explains how to run the tests locally.
-
-## Docker Installation
-
-It is required to have Docker running on your machine in order to build and run the tests in the Dockerfiles.
-See <https://docs.docker.com/engine/installation/> for more information on how to install.
-
-## Convenience Scripts
-
-We have added a number of default run scripts to the `package.json` file to simplify building and running your tests.
-
-### Configuring Docker Images
-
-The following two scripts need to be run first before you can move on to testing:
-
-- `yarn run docker-setup-android`: Pulls down the React Native Community Android image that serves as a base image when building the actual test image.
-
-- `yarn run docker-build-android`: Builds a test image with the latest dependencies and React Native library code, including a compiled Android test app.
-
-### Running Tests
-
-Once the test image has been built, it can be used to run our Android tests.
-
-- `yarn run test-android-run-unit` runs the unit tests, as defined in `scripts/run-android-docker-unit-tests.sh`.
-- `yarn run test-android-run-e2e` runs the end to end tests, as defined in `scripts/run-ci-e2e-tests.sh`.
-- `yarn run test-android-run-instrumentation` runs the instrumentation tests, as defined in `scripts/run-android-docker-instrumentation-tests.sh`.
-
-#### Instrumentation Tests
-
-The instrumentation test script accepts the following flags in order to customize the execution of the tests:
-
-`--filter` - A regex that filters which instrumentation tests will be run. (Defaults to .*)
-
-`--package` - Name of the java package containing the instrumentation tests (Defaults to com.facebook.react.tests)
-
-`--path` - Path to the directory containing the instrumentation tests. (Defaults to ./ReactAndroid/src/androidTest/java/com/facebook/react/tests)
-
-`--retries` - Number of times to retry a failed test before declaring a failure (Defaults to 2)
-
-For example, if locally you only wanted to run the InitialPropsTestCase, you could do the following:
-`yarn run test-android-run-instrumentation -- --filter="InitialPropsTestCase"`
-
-## Detailed Android Setup
-
-There are two Dockerfiles for use with the Android codebase.
-The base image used to build `reactnativecommunity/react-native-android` is located in the https://github.com/react-native-community/docker-android GitHub repository. 
-It contains all the necessary prerequisites required to run the React Android tests. 
-It is separated out into a separate Dockerfile because these are dependencies that rarely change and also because it is quite a beastly image since it contains all the Android dependencies for running Android and the emulators (~9GB).
-
-The good news is you should rarely have to build or pull down the base image!
-All iterative code updates happen as part of the `Dockerfile.android` image build.
-
-Lets break it down...
-
-First, you'll need to pull the base image. 
-You can use `docker pull` to grab the latest version of the `reactnativecommunity/react-native-android` base image.
-This is what you get when you run `yarn run docker-setup-android`.
-
-This will take quite some time depending on your connection and you need to ensure you have ~10GB of free disk space.
-
-Once you have downloaded the base image, the test image can be built using `docker build -t reactnativeci/android -f ./.circleci/Dockerfiles/Dockerfile.android .`. This is what `yarn run docker-build-android` does. Note that the `-t` flag is how you tell Docker what to name this image locally. You can then use `docker run -t reactnativeci/android` to run this image.
-
-Now that you've built the test image, you can run unit tests using what you've learned so far:
-
-```bash
-docker run --cap-add=SYS_ADMIN -it reactnativeci/android bash .circleci/Dockerfiles/scripts/run-android-docker-unit-tests.sh
-```
-
-> Note: `--cap-add=SYS_ADMIN` flag is required for the `.circleci/Dockerfiles/scripts/run-android-docker-unit-tests.sh` and `.circleci/Dockerfiles/scripts/run-android-docker-instrumentation-tests.sh` in order to allow the remounting of `/dev/shm` as writeable so the `buck` build system may write temporary output to that location.
-
-Every time you make any modifications to the codebase, including changes to the test scripts inside `.circleci/Dockerfiles/scripts`, you should re-run the `docker build ...` command in order for your updates to be included in your local docker test image.
-
-For rapid iteration, it's useful to keep in mind that Docker can pass along arbitrary commands to an image.
-For example, you can alternatively use Gradle in this manner:
-
-```bash
-docker run --cap-add=SYS_ADMIN -it reactnativeci/android ./gradlew RNTester:android:app:assembleRelease
-```

 # Contributing to React Native
 
-Thank you for your interest in contributing to React Native! From commenting on and triaging issues, to reviewing and sending Pull Requests, all contributions are welcome. We aim to build a vibrant and inclusive [ecosystem of partners, core contributors, and community](ECOSYSTEM.md) that goes beyond the main React Native GitHub repository.
+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 [facebook.com](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.
 
-The [Open Source Guides](https://opensource.guide/) website has a collection of resources for individuals, communities, and companies who want to learn how to run and contribute to an open source project. Contributors and people new to open source alike will find the following guides especially useful:
+## Our Development Process
 
-* [How to Contribute to Open Source](https://opensource.guide/how-to-contribute/)
-* [Building Welcoming Communities](https://opensource.guide/building-community/)
+Some of the core team will be working directly on GitHub. 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.
 
+### `master` is unsafe
 
-### [Code of Conduct](https://github.com/facebook/react-native/blob/HEAD/CODE_OF_CONDUCT.md)
+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 and version appropriately so you can lock into a specific version if need be.
 
-As a reminder, all contributors are expected to adhere to the [Code of Conduct](https://github.com/facebook/react-native/blob/HEAD/CODE_OF_CONDUCT.md).
+### Pull Requests
 
-## Ways to Contribute
+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.
 
-If you are eager to start contributing code right away, we have a list of [good first issues](https://github.com/facebook/react-native/labels/good%20first%20issue) that contain bugs which have a relatively limited scope. As you gain more experience and demonstrate a commitment to evolving React Native, you may be granted issue management permissions in the repository.
+**Please submit your pull request on the `master` branch**. If the fix is critical and should be included in a stable branch please mention it and it will be cherry picked into it by a project maintainer.
 
-There are other ways you can contribute without writing a single line of code. Here are a few things you can do to help out:
+*Before* submitting a pull request, please make sure the following is done…
 
-1. **Replying and handling open issues.** We get a lot of issues every day, and some of them may lack necessary information. You can help out by guiding people through the process of filling out the issue template, asking for clarifying information, or pointing them to existing issues that match their description of the problem. We cover more about this process in the [Issue Triage wiki](https://github.com/facebook/react-native/wiki/Triaging-GitHub-Issues).
-2. **Reviewing pull requests for the docs.** Reviewing [documentation updates](https://github.com/facebook/react-native-website/pulls) can be as simple as checking for spelling and grammar. If you encounter situations that can be explained better in the docs, click **Edit** at the top of most docs pages to get started with your own contribution.
-3. **Help people write test plans.** Some pull requests sent to the main repository may lack a proper test plan. These help reviewers understand how the change was tested, and can speed up the time it takes for a contribution to be accepted.
+1. Fork the repo and create your branch from `master`.
+2. **Describe your test plan in your commit.**
+  - If you've added code that should be tested, add tests!
+  - If you've changed APIs, update the documentation.
+  - If you've updated the docs, verify the website locally and submit screenshots if applicable.
 
-Each of these tasks is highly impactful, and maintainers will greatly appreciate your help.
+  ```
+  $ cd website
+  $ npm install && npm start
+  Open the following in your browser: http://localhost:8079/react-native/index.html
+  ```
 
-### Our Development Process
+3. Add the copyright notice to the top of any new files you've added.
+4. Ensure tests pass on Travis and Circle CI.
+5. Make sure your code lints (`node linter.js <files touched>`).
+6. If you haven't already, sign the [CLA](https://code.facebook.com/cla).
+7. Squash your commits (`git rebase -i`).
+   One intent alongside one commit makes it clearer for people to review and easier to understand your intention.
 
-We use GitHub issues and pull requests to keep track of bug reports and contributions from the community. All changes from engineers at Facebook will sync to [GitHub](https://github.com/facebook/react-native) through a bridge with Facebook's internal source control. Changes from the community are handled through GitHub pull requests. Once a change made on GitHub is approved, it will first be imported into Facebook's internal source control and tested against Facebook's codebase. Once merged at Facebook, the change will eventually sync back to GitHub as a single commit once it has passed Facebook's internal tests.
+> **Note:** It is not necessary to keep clicking `Merge master to your branch` on the PR page. You would want to merge master if there are conflicts or tests are failing. The Facebook-GitHub-Bot ultimately squashes all commits to a single one before merging your PR.
 
-You can learn more about the contribution process in the following documents:
+#### Copyright Notice for files
 
-* [Issues](https://github.com/facebook/react-native/wiki/Triaging-GitHub-Issues)
-* [Pull Requests](https://github.com/facebook/react-native/wiki/Managing-Pull-Requests)
+Copy and paste this to the top of your new file(s):
 
-We also have a thriving community of contributors who would be happy to help you get set up. You can reach out to us through [@ReactNative](http://twitter.com/reactnative) (the React Native team) and [@ReactNativeComm](http://twitter.com/reactnativecomm) (the React Native Community organization).

-### Repositories
+If you've added a new module, add a `@providesModule <moduleName>` at the end of the comment. This will allow the haste package manager to find it.
 
-The main repository, <https://github.com/facebook/react-native>, contains the React Native framework itself and it is here where we keep track of bug reports and manage pull requests.
+### Contributor License Agreement (CLA)
 
-There are a few other repositories you might want to familiarize yourself with:
+In order to accept your pull request, we need you to submit a CLA. You only need to do this once, so if you've done this for another Facebook open source project, you're good to go. If you are submitting a pull request for the first time, just let us know that you have completed the CLA and we can cross-check with your GitHub username.
 
-* **React Native website** which contains the source code for the website, including the documentation, located at <https://github.com/facebook/react-native-website>
-* **Releases**  Conversations for new releases are happening [in this discussion repo](https://github.com/reactwg/react-native-releases/discussions).
-* **Changelog** The changelog can be found [here](https://github.com/facebook/react-native/blob/main/CHANGELOG.md).
-* **Discussions** about the future of React Native take place in the <https://github.com/react-native-community/discussions-and-proposals> repository.
-* **High-quality plugins** for React Native can be found throughout the [React Native Community GitHub Organization](http://github.com/react-native-community/).
+[Complete your CLA here](https://code.facebook.com/cla)
 
-Browsing through these repositories should provide some insight into how the React Native open source project is managed.
+## Bugs
 
-## GitHub Issues
+### Where to Find Known Issues
 
-We use GitHub issues to track bugs exclusively. We have documented our issue handling processes in the [Issues wiki](https://github.com/facebook/react-native/wiki/Triaging-GitHub-Issues).
+We are using GitHub Issues for our public bugs. We keep a close eye on this and try to make it clear when we have an internal fix in progress. Before filing a new task, try to make sure your problem doesn't already exist.
+
+### Reporting New Issues
+
+The best way to get your bug fixed is to provide a reduced test case. Please provide either a public repository with a runnable example or a [Sketch](https://sketch.expo.io/).
 
 ### Security Bugs
 
-Facebook has a [bounty program](https://www.facebook.com/whitehat/) for the safe disclosure of security bugs. In those cases, please go through the process outlined on that page and do not file a public issue.
+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.
 
-## Helping with Documentation
+## How to Get in Touch
 
-The React Native documentation is hosted as part of the React Native website repository at https://github.com/facebook/react-native-website. The website itself is located at <https://reactnative.dev/> and it is built using [Docusaurus](https://docusaurus.io/). If there's anything you'd like to change in the docs, you can get started by clicking on the "Edit" button located on the upper right of most pages in the website.
+* [Facebook](https://www.facebook.com/groups/react.native.community/)
+* [Twitter](https://www.twitter.com/reactnative)
 
-If you are adding new functionality or introducing a change in behavior, we will ask you to update the documentation to reflect your changes.
+## Style Guide
 
-### Contributing to the Blog
+### Code
 
-The React Native blog is generated [from the Markdown sources for the blog](https://github.com/facebook/react-native-website/tree/HEAD/website/blog).
+#### General
 
-Please open an issue in the https://github.com/facebook/react-native-website repository or tag us on [@ReactNative on Twitter](http://twitter.com/reactnative) and get the go-ahead from a maintainer before writing an article intended for the React Native blog. In most cases, you might want to share your article on your own blog or writing medium instead. It's worth asking, though, in case we find your article is a good fit for the blog.
+* **Most important: Look around.** Match the style you see used in the rest of the project. This includes formatting, naming things in code, naming things in documentation.
+* Add trailing commas,
+* 2 spaces for indentation (no tabs)
+* "Attractive"
 
-We recommend referring to the [CONTRIBUTING](https://github.com/facebook/react-native-website/blob/HEAD/CONTRIBUTING.md) document for the `react-native-website` repository to learn more about contributing to the website in general.
+#### JavaScript
 
-## Contributing Code
+* Use semicolons;
+* `'use strict';`
+* Prefer `'` over `"`
+* Do not use the optional parameters of `setTimeout` and `setInterval`
+* 80 character line length
 
-Code-level contributions to React Native generally come in the form of [pull requests](https://help.github.com/en/articles/about-pull-requests). These are done by forking the repo and making changes locally. Directly in the repo, there is the [`rn-tester` app](/packages/rn-tester) that you can install on your device (or simulators) and use to test the changes you're making to React Native sources.
+#### JSX
 
-The process of proposing a change to React Native can be summarized as follows:
+* Prefer `"` over `'` for string literal props
+* When wrapping opening tags over multiple lines, place one prop per line
+* `{}` of props should hug their values (no spaces)
+* Place the closing `>` of opening tags on the same line as the last prop
+* Place the closing `/>` of self-closing tags on their own line and left-align them with the opening `<`
 
-1. Fork the React Native repository and create your branch from `main`.
-2. Make the desired changes to React Native sources. Use the `packages/rn-tester` app to test them out.
-3. If you've added code that should be tested, add tests.
-4. If you've changed APIs, update the documentation, which lives in [another repo](https://github.com/facebook/react-native-website/).
-5. Ensure the test suite passes, either locally or on CI once you opened a pull request.
-6. Make sure your code lints (for example via `yarn lint --fix`).
-7. Push the changes to your fork.
-8. Create a pull request to the React Native repository.
-9. Review and address comments on your pull request.
-    1. A bot may comment with suggestions. Generally we ask you to resolve these first before a maintainer will review your code.
-    2. If changes are requested and addressed, please [request review](https://docs.github.com/en/github/collaborating-with-pull-requests/proposing-changes-to-your-work-with-pull-requests/requesting-a-pull-request-review) to notify reviewers to take another look.
-10. If you haven't already, please complete the [Contributor License Agreement](https://github.com/facebook/react-native/wiki/Contributor-License-Agreement) ("CLA"). **[Complete your CLA here.](https://code.facebook.com/cla)**
+#### Objective-C
 
-If all goes well, your pull request will be merged. If it is not merged, maintainers will do their best to explain the reason why.
+* Space after `@property` declarations
+* Brackets on *every* `if`, on the *same* line
+* `- method`, `@interface`, and `@implementation` brackets on the following line
+* *Try* to keep it around 80 characters line length (sometimes it's just not possible...)
+* `*` operator goes with the variable name (e.g. `NSObject *variableName;`)
 
-### Step-by-step Guide
+#### Java
 
-Whenever you are ready to contribute code, check out our [step-by-step guide to sending your first pull request](https://github.com/facebook/react-native/wiki/How-to-Open-a-Pull-Request), or read the [How to Contribute Code](https://github.com/facebook/react-native/wiki/How-to-Contribute-Code) wiki for more details.
+* If a method call spans multiple lines closing bracket is on the same line as the last argument.
+* If a method header doesn't fit on one line each argument goes on a separate line.
+* 100 character line length
 
-### Tests
+### Documentation
 
-Tests help us prevent regressions from being introduced to the codebase. The GitHub repository is continuously tested using Circle and Appveyor, the results of which are available through the Checks functionality on [commits](https://github.com/facebook/react-native/commits/HEAD) and pull requests. You can learn more about running and writing tests in the [Tests wiki](http://github.com/facebook/react-native/wiki/Tests).
+* Do not wrap lines at 80 characters - configure your editor to soft-wrap when editing documentation.
 
-## Community Contributions
+## License
 
-Contributions to React Native are not limited to GitHub. You can help others by sharing your experience using React Native, whether that is through blog posts, presenting talks at conferences, or simply sharing your thoughts on Twitter and tagging @ReactNative.

-## Where to Get Help
-
-As you work on React Native, it is natural that sooner or later you may require help. In addition to the resources listed in [SUPPORT](.github/SUPPORT.md), people interested in contributing may take advantage of the following:
-
-* **Twitter**. The React Native team at Facebook has its own account at [@reactnative](https://twitter.com/reactnative), and the React Native Community uses [@reactnativecomm](https://twitter.com/reactnativecomm). If you feel stuck, or need help contributing, please do not hesitate to reach out.
-* **Proposals Repository**. If you are considering working on a feature large in scope, consider [creating a proposal first](https://github.com/react-native-community/discussions-and-proposals). The community can help you figure out the right approach, and we'd be happy to help.
-* **React Native Community Discord**. While we try to hold most discussions in public, sometimes it can be beneficial to have conversations in real time with other contributors. People who have demonstrated a commitment to moving React Native forward through sustained contributions to the project may eventually be invited to join the React Native Community Discord.

+# Dockerfile Tests
+
+This is a high level overview of the test configuration using docker. It explains how to run the tests locally
+and how they integrate with the Jenkins Pipeline script to run the automated tests on ContainerShip <https://www.containership.io/>.
+
+## Docker Installation
+
+It is required to have Docker running on your machine in order to build and run the tests in the Dockerfiles.
+See <https://docs.docker.com/engine/installation/> for more information on how to install.
+
+## Convenience NPM Run Scripts
+
+We have added a number of default run scripts to the `package.json` file to simplify building and running your tests.
+
+`npm run test-android-setup` - Pulls down the base android docker image used for running the tests
+
+`npm run test-android-build` - Builds the docker image used to run the tests
+
+`npm run test-android-run-unit` - Runs all the unit tests that have been built in the latest react/android docker image (note: you need to run test-android-build before executing this, if the image does not exist it will fail)
+
+`npm run test-android-run-instrumentation` - Runs all the instrumentation tests that have been built in the latest react/android docker image (note: you need to run test-android-build before executing this, if the image does not exist it will fail). You can also pass additional flags to filter which tests instrumentation tests are run. Ex: `npm run test-android-run-instrumentation -- --filter=TestIdTestCase` to only run the TestIdTestCase instrumentation test. See below for more information
+on the instrumentation test flags.
+
+`npm run test-android-run-e2e` - Runs all the end to end tests that have been built in the latest react/android docker image (note: you need to run test-android-build before executing this, if the image does not exist it will fail)
+
+`npm run test-android-unit` - Builds and runs the android unit tests.
+
+`npm run test-android-instrumentation` - Builds and runs the android instrumentation tests.
+
+`npm run test-android-e2e` - Builds and runs the android end to end tests.
+
+## Detailed Android Setup
+
+There are two Dockerfiles for use with the Android codebase.
+
+The `Dockerfile.android-base` contains all the necessary prerequisites required to run the React Android tests. It is
+separated out into a separate Dockerfile because these are dependencies that rarely change and also because it is quite
+a beastly image since it contains all the Android depedencies for running android and the emulators (~9GB).
+
+The good news is you should rarely have to build or pull down the base image! All iterative code updates happen as
+part of the `Dockerfile.android` image build.
+
+So step one...
+
+`docker pull containership/android-base:latest`
+
+This will take quite some time depending on your connection and you need to ensure you have ~10GB of free disk space.
+
+Once this is done, you can run tests locally by executing two simple commands:
+
+1. `docker build -t react/android -f ./ContainerShip/Dockerfile.android .`
+2. `docker run --cap-add=SYS_ADMIN -it react/android bash ContainerShip/scripts/run-android-docker-unit-tests.sh`
+
+> Note: `--cap-add=SYS_ADMIN` flag is required for the `ContainerShip/scripts/run-android-docker-unit-tests.sh` and
+`ContainerShip/scripts/run-android-docker-instrumentation-tests.sh` in order to allow the remounting of `/dev/shm` as writeable
+so the `buck` build system may write temporary output to that location
+
+Every time you make any modifications to the codebase, you should re-run the `docker build ...` command in order for your
+updates to be included in your local docker image.
+
+The following shell scripts have been provided for android testing:
+
+`ContainerShip/scripts/run-android-docker-unit-tests.sh` - Runs the standard android unit tests
+
+`ContainerShip/scripts/run-android-docker-instrumentation-tests.sh` - Runs the android instrumentation tests on the emulator. *Note* that these
+tests take quite some time to run so there are various flags you can pass in order to filter which tests are run (see below)
+
+`ContainerShip/scripts/run-ci-e2e-tests.sh` - Runs the android end to end tests
+
+#### ContainerShip/scripts/run-android-docker-instrumentation-tests.sh
+
+The instrumentation test script accepts the following flags in order to customize the execution of the tests:
+
+`--filter` - A regex that filters which instrumentation tests will be run. (Defaults to .*)
+
+`--package` - Name of the java package containing the instrumentation tests (Defaults to com.facebook.react.tests)
+
+`--path` - Path to the directory containing the instrumentation tests. (Defaults to ./ReactAndroid/src/androidTest/java/com/facebook/react/tests)
+
+`--retries` - Number of times to retry a failed test before declaring a failure (Defaults to 2)
+
+For example, if locally you only wanted to run the InitialPropsTestCase, you could do the following:
+
+`docker run --cap-add=SYS_ADMIN -it react/android bash ContainerShip/scripts/run-android-docker-instrumentation-tests.sh --filter="InitialPropsTestCase"`
+
+# Javascript Setup
+
+There is a single Dockerfile for use with the javascript codebase.
+
+The `Dockerfile.javascript` base requires all the necessary dependencies for running Javascript tests.
+
+Any time you make an update to the codebase, you can build and run the javascript tests with the following three commands:
+
+1. `docker build -t react/js -f ./ContainerShip/Dockerfile.javascript .`
+2. `docker run -it react/js yarn test --maxWorkers=4`
+3. `docker run -it react/js yarn run flow -- check`

-# The React Native Ecosystem
-
-We aim to build a vibrant and inclusive ecosystem of partners, core contributors, and community that goes beyond the main React Native GitHub repository. This document explains the roles and responsibilities of various stakeholders and provides guidelines for the community organization. The structure outlined in this document has been in place for a while but hadn't been written down before.
-
-There are three types of stakeholders:
-
-* **Partners:** Companies that are significantly invested in React Native and have been for years.
-* **Core Contributors:** Individual people who contribute to the React Native project.
-* **Community Contributors:** Individuals who support projects in the [react-native-community](https://github.com/react-native-community) organization.
-
-## Partners
-
-Partners are companies that are significantly invested in React Native and have been for years. Informed by their use of React Native, they push for improvements of the core and/or the ecosystem around it. Partners think of React Native as a product: they understand the trade offs that the project makes as well as future plans and goals. Together we shape the vision for React Native to make it the best way to build applications.
-
-React Native's current set of partners include Callstack, Expo, Facebook, Infinite Red, Microsoft and Software Mansion. Many engineers from these companies are core contributors, and their partner responsibilities also include:
-
-* **[Callstack](https://callstack.com/):** Manages releases, maintains the [React Native CLI](https://github.com/react-native-community/react-native-cli) and organizes [React Native EU](https://react-native.eu/)
-* **[Expo](https://expo.io/):** Builds [expo](https://github.com/expo/expo) on top of React Native to simplify app development
-* **[Facebook](https://opensource.facebook.com):** Oversees the React Native product and maintains the [React Native core repo](https://reactnative.dev/) 
-* **[Infinite Red](https://infinite.red/):** Maintains the [ignite cli/boilerplate](https://github.com/infinitered/ignite), organizes [Chain React Conf](https://cr.infinite.red/)
-* **[Microsoft](http://aka.ms/reactnative):** Develops [React Native Windows](https://github.com/Microsoft/react-native-windows) and [React Native macOS](https://github.com/microsoft/react-native-macos) for building apps that target Windows and macOS
-* **[Software Mansion](https://swmansion.com/):** Maintain core infrastructure including JSC, Animated, and other popular third-party plugins.
-
-In terms of open source work, pull requests from partners are commonly prioritized. When you are contributing to React Native, you'll most likely meet somebody who works at one of the partner companies and who is a core contributor:
-
-## Core Contributors
-
-Core contributors are individuals who contribute to the React Native project. A core contributor is somebody who displayed a lasting commitment to the evolution and maintenance of React Native. The work done by core contributors includes responsibilities mentioned in the “Partners” section above, and concretely means that they:
-
-* Consistently contribute high quality changes, fixes and improvements
-* Actively review changes and provide quality feedback to contributors
-* Manage the release process of React Native by maintaining release branches, communicating changes to users and publishing releases
-* Love to help out other users with issues on GitHub
-* Mentor and encourage first time contributors
-* Identify React Native community members who could be effective core contributors
-* Help build an inclusive community with people from all backgrounds
-* Are great at communicating with other contributors and the community in general
-
-These are behaviors we have observed in our existing core contributors. They aren't strict rules but rather outline their usual responsibilities. We do not expect every core contributor to do all of the above things all the time. Most importantly, we want to create a supportive and friendly environment that fosters collaboration. Above all else, **we are always polite and friendly.**
-
-Core contributor status is attained after consistently contributing and taking on the responsibilities outlined above and granted by other core contributors. Similarly, after a long period of inactivity, a core contributor may be removed.
-
-We aim to make contributing to React Native as easy and transparent as possible. All important topics are handled through a [discussion or RFC process on GitHub](https://github.com/react-native-community/discussions-and-proposals). We are always looking for active, enthusiastic members of the React Native community to become core contributors.
-
-## Community Contributors
-
-Community contributors are individuals who support projects in the [react-native-community](https://github.com/react-native-community) organization. This organization exists as an incubator for high quality components that extend the capabilities of React Native with functionality that many but not all applications require. Facebook engineers will provide guidance to help build a vibrant community of people and components that make React Native better.
-
-This structure has multiple benefits:
-
-* Keep the core of React Native small, which improves performance and reduces the surface area
-* Provide visibility to projects through shared representation, for example on the React Native website or on Twitter
-* Ensure a consistent and high standard for code, documentation, user experience, stability and contributions for third-party components
-* Upgrade the most important components right away when we make breaking changes and move the ecosystem forward at a fast pace
-* Find new maintainers for projects that are important but were abandoned by previous owners
-
-Additionally, some companies may choose to sponsor the development of one or many of the packages that are part of the community organization. They will commit to maintain projects, triage issues, fix bugs and develop features. In turn, they will be able to gain visibility for their work, for example through a mention of active maintainers in the README of individual projects after a consistent period of contributions. Such a mention may be removed if maintainers abandon the project.
-
-If you are working on a popular component and would like to move it to the React Native community, please create an issue on the [discussions-and-proposals repository](https://github.com/react-native-community/discussions-and-proposals).

+# UIExplorer
+
+The UIExplorer is a sample app that showcases React Native views and modules.
+
+## Running this app
+
+Before running the app, make sure you ran:
+
+    git clone https://github.com/facebook/react-native.git
+    cd react-native
+    npm install
+
+### Running on iOS
+
+Mac OS and Xcode are required.
+
+- Open `Examples/UIExplorer/UIExplorer.xcodeproj` in Xcode
+- Hit the Run button
+
+See [Running on device](https://facebook.github.io/react-native/docs/running-on-device.html) if you want to use a physical device.
+
+### Running on Android
+
+You'll need to have all the [prerequisites](https://github.com/facebook/react-native/tree/master/ReactAndroid#prerequisites) (SDK, NDK) for Building React Native installed.
+
+Start an Android emulator ([Genymotion](https://www.genymotion.com) is recommended).
+
+    cd react-native
+    ./gradlew :Examples:UIExplorer:android:app:installDebug
+    ./packager/packager.sh
+
+_Note: Building for the first time can take a while._
+
+Open the UIExplorer app in your emulator.
+
+See [Running on Device](https://facebook.github.io/react-native/docs/running-on-device.html) in case you want to use a physical device.
+
+### Running with Buck
+
+Follow the same setup as running with gradle.
+
+Install Buck from [here](https://buckbuild.com/setup/install.html).
+
+Run the following commands from the react-native folder:
+
+    ./gradlew :ReactAndroid:packageReactNdkLibsForBuck
+    buck fetch uiexplorer
+    buck install -r uiexplorer
+    ./packager/packager.sh
+
+_Note: The native libs are still built using gradle. Full build with buck is coming soon(tm)._
+
+## Built from source
+
+Building the app on both iOS and Android means building the React Native framework from source. This way you're running the latest native and JS code the way you see it in your clone of the github repo.
+
+This is different from apps created using `react-native init` which have a dependency on a specific version of React Native JS and native code, declared in a `package.json` file (and `build.gradle` for Android apps).
