-# Circle CI
-
-This directory is home to the Circle CI configuration files. Circle is our continuous integration service provider. You can see the overall status of React Native's builds at https://circleci.com/gh/facebook/react-native
-
-You may also see an individual PR's build status by scrolling down to the Checks section in the PR.
-
-## Purposes
-
-We use CircleCI for mainly 3 purposes:
-
-1. Testing changes
-2. Release Nightlies
-3. Release Stable Versions of React Native
-
-When testing changes, we run all the tests on commits that lands on `main`. For commits in PR, we try to understand which kind of changes the PR is about and we try to selectively run only the relevant tests. so, for example, if a PR only touches iOS files, we are going to run only iOS tests.
-
-A Nighly job runs every day at around 9:00 PM, GMT. They run from `main` and they publish a version of React Native using the current state of the codebase, creating a version number that follows the format: `0.<current-version+1>.0-nightly-<YYYYMMDD>-<short-commit-hash>`.
-The nightly job also publish all the monorepo packages, taking care of updating the transitive dependencies of those packages.
-
-Stable versions are released manually by the Release Crew and they run from a stable branch. Stable branches have the shape of `0.<version>-stable`.
-
-## How It Works?
-
-CircleCI execution is now split in two steps:
-- Setup
-- Testing
-
-The setup step takes care of analyzing the changes in the PR and of deciding which jobs needs to run.
-
-The testing flow is a set of workflows that executes the required tests.
-
-### Setup
-
-The code of the setup workflow lives in the root [`config.yml`](https://github.com/facebook/react-native/blob/main/.circleci/config.yml) file.
-It uses the `Continuation orb` from CircleCI to start a CI flow that depends on the changes present in the PR.
-
-If the changes are not coming from a PR (either a simple commit or if the CI is running on main) **we always run all the tests** as a cautionary measure.
-
-The setup job has also to expose all the pipeline parameters that we would need to pass to the actual workflow. Those parameters are **automatically forwarded** to the workflows that are started as a result of the setup.
-
-The setup job uses a JS script to carry on its logic. The [`pipeline_selection.js`](https://github.com/facebook/react-native/blob/main/scripts/circleci/pipeline_selection.js) script can be invoked with two commands:
-- `filter-jobs`
-- `create-configs`
-
-The **`filter-jobs`** command takes care of creating a JSON representation of the tests we need to run based on the changes in the PR.
-
-The **`create-configs`** command consumes the JSON representation to create a CircleCI configuration that can then executes all the required tests.
-
-#### Creating a Configuration
-
-To create a configuration, the `pipeline-selection` scripts collates together various pieces of `YML` files that lives in the [`Configurations` folder](https://github.com/facebook/react-native/tree/main/.circleci/configurations).
-
-The order in which these files are appended is **important** and it always contains the following.:
-
-1. `top_level.yml`: this file contains some high level directives for CircleCI, like the version, the list of orbs, the cache-keys, and the pipeline parameters that can be used by the workflows.
-2. `executors.yml`: this file contains the list of the executors used in our jobs and their configurations.
-3. `commands.yml`: this file contains all the commands that can be used by jobs to executes. Commands are reusable functions that are shared by multiple jobs.
-4. `jobs.yml`: this file contains the jobs that are used by workflows to carry on some specific tasks. They are composed of sequential commands.
-5. `workflows.yml`: this file contains the shared workflows that needs to (or can) be always executed, no matter which kind of changes are pushed to CI. An example of these workflows is `analysis` (which is always executed) or `nightly` (which can be executed if a specific pipeline parameter is passed to the CI).
-
-Then, the `pipeline_selection create-configs` attach some specific test workflows, depending on the changes that are present in the PR. These change-dependent workflows live in the [`test_workflows`](https://github.com/facebook/react-native/tree/main/.circleci/configurations/test_workflows) folder.
-These workflows are:
-* `testAll.yml` => runs all the possible tests. This workflow is executed on main and on PRs which change set touches both iOS and Android
-* `testAndroid.yml` => runs all the build steps and Android tests. This is used on changes that happens on the Android codebase and infra (`ReactAndroid` folder)
-* `testIOS.yml` => runs all the build steps and iOS tests. This is used on changes that happens on the iOS codebase and infra (`React` folder)
-* `testE2E.yml` => runs the E2E tests. As of today, E2E tests can be triggered if the commit message contains the `#run-e2e-tests` tag.
-* `testJS.yml` => For all the changes that do not touch native/platform code, we only run JS tests.
-
-Notice that if there are changes on files that do not represents code (for example `.md` files like this one or the `Changelog`) we don't run any CI.
-
-## Test workflows
-
-The test workflows for native code are composed of 2 parts:
-- building React Native
-- testing
-
-Building React Native requires us to build several parts of it:
-1. We need to build the Hermes JS engine
-2. We need to build Android to create prebuilds
-3. We need to package everything in an npm package that will mimic a React native release
-4. We need to create a local maven repository
-
-### Building Hermes Engine
-
-#### Android
-The `build_android` workflows takes care of building the Android version of Hermes and to put it properly in a local maven repository.
-See the [Build Android](#build_android) section below.
-
-#### iOS
-Hermes is a very complicated item to build for iOS.
-It is composed of the Hermes compiler (HermesC) and of the actual engine.
-
-Hermes is shipped as a universal XCFramework. This means that we need to build all the architecture slices and then put them together in the XCFramework archive.
-We also need to build 2 configurations: Debug and Release.
-
-In order to be efficient and to save costs, we parallelize the process as much as possible:
-
-1. We prepare the environment for building Hermes.
-2. We build HermesC which is required by all the slices.
-3. We start 8 jobs to build all the required slices in parallel:
-    1. `iphone` slice, Debug mode
-    1. `iphonesimulator` slice, Debug mode
-    1. `macos` slice, Debug mode
-    1. `catalyst` slice, Debug mode
-    1. `iphone` slice, Release mode
-    1. `iphonesimulator` slice, Release mode
-    1. `macos` slice, Release mode
-    1. `catalyst` slice, Release mode
-4. We then have 2 jobs to create the Debug and Release tarballs in parallel.
-    1. The Debug job receives the 4 Debug slices
-    1. The Release job receives the 4 Release slices
-
-The `Debug` and `Release` tarball are then uploaded as artifacts. Notice that these we use these artifacts to **test the release** of React Native.
-
-While building Hermes, we take also care of building the dSYMs. A dSYM (Debug Symbols) is an archive that contains the Debug Symbols that users can load to de-symbolicate the Hermes Stack traces. These symbols are published when we create a React Native release.
-
-A lot of these build steps are automated by some shell scripts that lives in the [`react-native/packages/react-native/sdks/hermes-engine/utils` folder](https://github.com/facebook/react-native/tree/main/packages/react-native/sdks/hermes-engine/utils).
-
-### Build Android
-
-The android build is all managed by Gradle, so building android should be as easy as calling a [`gradle` command](https://github.com/facebook/react-native/blob/main/.circleci/configurations/jobs.yml#L268-L274).
-
-The relevant part here is that the build android generates a `maven-local` repository that is passed to the [`build_npm_package`](https://github.com/facebook/react-native/blob/main/.circleci/configurations/jobs.yml#L1182) and that we use to test the releases.
-
-### Build NPM package
-
-This job is the responsible to create an NPM package that is suitable to be released or tested in CI.
-If we are in a release flow (for example the Nightly workflow), it also proceed with the publication.
-
-The job can be invoked with different parameters:
-- `dry-run` => it does not publish anything, but prepare the artifacts to be used for testing
-- `nightly` => it creates the artifacts and publish a nightly version of React Native.
-- `release` => it creates the artifacts and publish a stable version of React Native.
-
-The build NPM package takes all the artifacts produced in the previous steps (iOS' Hermes, iOS' Hermes dSYMs, Android's `maven-local`) and creates an npm package packing all the code.
-
-If in a release mode, it also proceed publishing the NPM package to NPM, and the artifacts to Maven central, which we use to distribute all the artifacts.
-
-This job also uploads the `maven-local` repository and a zipped version of the npm package to CircleCI's artifacts. We use these artifacts to **test the release** of React Native.
-
-## Testing React Native
-React Native tests runs in two different scenarios:
-- RNTester
-- A New App
-
-### RNTester
-RNTester is our internal testing app. It is a fully working React Native app that lives in the [`react-native/packages/rn-tester` folder](https://github.com/facebook/react-native/tree/main/packages/rn-tester) of the repository.
-RNTester is an app which contains code that exercise most part of the React Native frameworks.
-It also has the feature of building React Native **from source**. For that reason, it does not have to wait for the NPM package to be ready, but RNTester's tests can start as soon as the `build_android` step and the step that builds Hermes for iOS are done.
-
-Notice the Tests on RNTester for iOS consumes the Hermes engine that is built in the previous steps.
-
-For Android, these tests creates an APK that is uploaded as an artifact in CircleCI. We use these artifacts to **test the releases** of React Native..
-
-### A New App
-The React Native repo contains a template app in the [`react-native/packages/react-native/template` folder]() that is used to spin up a new application that is preconfigured with React Native.
-
-We have several tests that we run starting from the template, testing various configurations:
-- Debug/Release
-- JSC/Hermes (two different JS engine we support)
-- New/Old Architecture (two different Architectures for React Native)
-
-We want to test all the React Native changes against the template, but we can't publish a React native version on each change that is merged. Therefore, to run tests on the template we use a NPM registry proxy called [Verdaccio](https://verdaccio.org/).
-
-When running a Template test our CI follows roughly these steps:
-1. Prepare the executor
-2. Start a Verdaccio server
-3. Publish on Verdaccio all the monorepo [packages](https://github.com/facebook/react-native/tree/main/packages) on which React Native depends on.
-4. Publish on Verdaccio the react-native NPM package that has been created in the NPM step
-5. Spin up a new React native apps from the template, downloading react-native from Verdaccio.
-
-In this way, we are sure that we can test all the changes that happen in React Native on a new React Native app.

+
+    * 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.

+  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,

 # 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 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.
 
-To learn more about how to contribute check out the Contributing section on the React Native website:
-* https://reactnative.dev/contributing/overview
+## 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.
+
+## 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.
+
+## 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.
+
+To see what changes are coming and provide better feedback to React Native contributors, use the [latest release candidate](http://facebook.github.io/react-native/versions.html) when possible. By the time a release candidate is released, the changes it contains will have been shipped in production Facebook apps for over two weeks.
+
+## Bugs
+
+#### Where to Find Known Issues
+
+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.
+
+Questions and feature requests are tracked elsewhere:
+
+  - 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).
+
+#### Reporting New Issues
+
+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.
+
+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.
+
+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.
+
+## How to Get in Touch
+
+Many React Native users are active on [Stack Overflow](http://stackoverflow.com/questions/tagged/react-native).
+
+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.
+
+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.
+
+The React Native team sends out periodical updates through the following channels:
+
+* [Blog](https://facebook.github.io/react-native/blog/)
+* [Twitter](https://www.twitter.com/reactnative)
+
+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.
+
+## 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.
+
+## 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.
+
+*Before* submitting a pull request, please make sure the following is done…
+
+1. Fork the repo and create your branch from `master`.
+2. Add the copyright notice to the top of any new files you've added.
+3. Describe your **test plan** in your commit.
+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.
+
+> **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.
+
+#### Test plan
+
+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.
+
+  - 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 (see `website/README.md`)
+
+See "What is a Test Plan?" to learn more:
+https://medium.com/@martinkonicek/what-is-a-test-plan-8bfc840ec171#.y9lcuqqi9
+
+#### Continuous integration tests
+
+Make sure all **tests pass** on both [Travis][travis] and [Circle CI][circle]. PRs that break tests are unlikely to be merged.
+
+You can learn more about running tests and contributing to React Native here: https://facebook.github.io/react-native/docs/testing.html
+
+[travis]: https://travis-ci.org/facebook/react-native
+[circle]: http://circleci.com/gh/facebook/react-native
+
+#### Breaking changes
+
+When adding a new breaking change, follow this template in your pull request:
+
+```
+### New breaking change here
+
+- **Who does this affect**:
+- **How to migrate**:
+- **Why make this breaking change**:
+- **Severity (number of people affected x effort)**:
+```
+
+If your pull request is merged, a core contributor will update the [list of breaking changes](https://github.com/facebook/react-native/wiki/Breaking-Changes) which is then used to populate the release notes.
+
+#### Copyright Notice for files
+
+Copy and paste this to the top of your new file(s):
+
+```JS
+/**
+ * Copyright (c) 2015-present, Facebook, Inc.
+ * All rights reserved.
+ *
+ * This source code is licensed under the BSD-style license found in the
+ * LICENSE file in the root directory of this source tree. An additional grant
+ * of patent rights can be found in the PATENTS file in the same directory.
+ */
+```
+
+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.
+
+### Contributor License Agreement (CLA)
+
+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.
+
+Complete your CLA here: https://code.facebook.com/cla
+
+## Style Guide
+
+Our linter will catch most styling issues that may exist in your code. You can check the status of your code styling by simply running `node linter.js <files touched>`.
+
+However, there are still some styles that the linter cannot pick up.
+
+### Code Conventions
+
+#### General
+
+* **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"
+
+#### JavaScript
+
+* Use semicolons;
+* `'use strict';`
+* Prefer `'` over `"`
+* Do not use the optional parameters of `setTimeout` and `setInterval`
+* 80 character line length
+
+#### JSX
+
+* 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 `<`
+
+#### Objective-C
+
+* 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;`)
+
+#### Java
+
+* 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
+
+### Documentation
+
+* Do not wrap lines at 80 characters - configure your editor to soft-wrap when editing documentation.

+# 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 had not been written down before.
-
-There are three types of stakeholders:
-
-* **Partners:** Companies significantly invested in React Native and take responsibility for the React Native vision and community.
-* **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 demonstrate ownership. Informed by their use of React Native, they push for improvements of the core and/or the ecosystem around it. Examples of this may include large scale contributions to `react-native` or owning essential tools or libraries.
-
-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.
-
-### Application process
-To become a React Native partner, an existing partner needs to refer and champion your application. Partners will undergo a 3 month incubating period, after which Partners will vote to convert to full membership.
-
-Partnership is not a status symbol, it is a commitment to invest significant resources into improving React Native.
-
-Maintaining partner status requires consistently meeting the baseline responsibilities, including:
-* Attending monthly meeting.
-* Contributing to the release process.
-* Engaging in the core contributor Discord.
-
-Examples of contributing to the release include being a [community releaser](https://reactnative.dev/contributing/release-roles-responsibilities#release-role-2-community-releaser), testing new releases, and technical support for release issues.
-
-### Current partners:

-
-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 (~6 months or more), a core contributor may be contacted to understand if they’re still interested in being part of the program.
-
-You can use this [form](https://forms.gle/4jpA4QeNUvAUDnNe8) to either:
-* Apply yourself to become a Core Contributor. Make sure to include a list of valuable contributions you did to the React Native repository and ecosystem.
-* Nominate someone to become a Core Contributor.
-
-As a core contributor, you will have access to the core contributor Discord which is used for light-weight coordination and discussion.
-
-**We aim to make contributing to React Native as easy and transparent as possible.** We have discussion groups dedicated to the [new architecture rollout](https://github.com/reactwg/react-native-new-architecture), [releases](https://github.com/reactwg/react-native-releases), and [general questions and proposals](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. Meta 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).

+      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.

+          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

+          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

+      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.
