 # 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.fb.com/codeofconduct/) so that you can understand what actions will and will not be tolerated.
+## Our Pledge
+
+In the interest of fostering an open and welcoming environment, we as
+contributors and maintainers pledge to make participation in our project and
+our community a harassment-free experience for everyone, regardless of age, body
+size, disability, ethnicity, sex characteristics, gender identity and expression,
+level of experience, education, socio-economic status, nationality, personal
+appearance, race, religion, or sexual identity and orientation.
+
+## Our Standards
+
+Examples of behavior that contributes to creating a positive environment
+include:
+
+* Using welcoming and inclusive language
+* Being respectful of differing viewpoints and experiences
+* Gracefully accepting constructive criticism
+* Focusing on what is best for the community
+* Showing empathy towards other community members
+
+Examples of unacceptable behavior by participants include:
+
+* The use of sexualized language or imagery and unwelcome sexual attention or
+  advances
+* Trolling, insulting/derogatory comments, and personal or political attacks
+* Public or private harassment
+* Publishing others' private information, such as a physical or electronic
+  address, without explicit permission
+* Other conduct which could reasonably be considered inappropriate in a
+  professional setting
+
+## Our Responsibilities
+
+Project maintainers are responsible for clarifying the standards of acceptable
+behavior and are expected to take appropriate and fair corrective action in
+response to any instances of unacceptable behavior.
+
+Project maintainers have the right and responsibility to remove, edit, or
+reject comments, commits, code, wiki edits, issues, and other contributions
+that are not aligned to this Code of Conduct, or to ban temporarily or
+permanently any contributor for other behaviors that they deem inappropriate,
+threatening, offensive, or harmful.
+
+## Scope
+
+This Code of Conduct applies within all project spaces, and it also applies when
+an individual is representing the project or its community in public spaces.
+Examples of representing a project or community include using an official
+project e-mail address, posting via an official social media account, or acting
+as an appointed representative at an online or offline event. Representation of
+a project may be further defined and clarified by project maintainers.
+
+## Enforcement
+
+Instances of abusive, harassing, or otherwise unacceptable behavior may be
+reported by contacting the project team at <opensource-conduct@fb.com>. All
+complaints will be reviewed and investigated and will result in a response that
+is deemed necessary and appropriate to the circumstances. The project team is
+obligated to maintain confidentiality with regard to the reporter of an incident.
+Further details of specific enforcement policies may be posted separately.
+
+Project maintainers who do not follow or enforce the Code of Conduct in good
+faith may face temporary or permanent repercussions as determined by other
+members of the project's leadership.
+
+## Attribution
+
+This Code of Conduct is adapted from the [Contributor Covenant][homepage], version 1.4,
+available at https://www.contributor-covenant.org/version/1/4/code-of-conduct.html

+
+Yoga is an embeddable and performant flexbox layout engine with bindings for multiple languages.
 
 ## Building
-Yoga builds with [buck](https://buckbuild.com). Make sure you install buck before contributing to Yoga. Yoga's main implementation is in C, with bindings to supported languages and frameworks. When making changes to Yoga please ensure the changes are also propagated to these bindings when applicable.
 
-## Testing
-For testing we rely on [gtest](https://github.com/google/googletest) as a submodule. After cloning Yoga run `git submodule init` followed by `git submodule update`.
+Yoga's main implementation targets C++ 20 with accompanying build logic in CMake. A wrapper is provided to build the main library and run unit tests.
 
-For any changes you make you should ensure that all the tests are passing. In case you make any fixes or additions to the library please also add tests for that change to ensure we don't break anything in the future. Tests are located in the `tests` directory. Run the tests by executing `buck test //:yoga`.
+```sh
+./unit_tests <Debug|Release>
+```
 
-Instead of manually writing a test which ensures parity with web implementations of Flexbox you can run `gentest/gentest.rb` to generate a test for you. You can write html which you want to verify in Yoga, in `gentest/fixtures` folder, such as the following.
+While not required, this script will use [ninja](https://ninja-build.org/) if it is installed for faster builds.
+
+Yoga is additionally part of the [vcpkg](https://github.com/Microsoft/vcpkg/) collection of ports maintained by Microsoft and community contributors. If the version is out of date, please [create an issue or pull request](https://github.com/Microsoft/vcpkg) on the vcpkg repository.
+
+## Adding Tests
+
+Many of Yoga's tests are automatically generated, using HTML fixtures describing node structure. These are rendered in Chrome to generate an expected layout result for the tree. New fixtures can be added to `gentest/fixtures`.
 
 ```html
 <div id="my_test" style="width: 100px; height: 100px; align-items: center;">

 </div>
 ```
 
-Run `gentest/gentest.rb` to generate test code and re-run `buck test //:yoga` to validate the behavior. One test case will be generated for every root `div` in the input html.
+To generate new tests from added fixtures:
 
-You may need to install the latest watir-webdriver gem (`gem install watir-webdriver`) and [ChromeDriver](https://sites.google.com/a/chromium.org/chromedriver/) to run `gentest/gentest.rb` Ruby script.
+1. Ensure you have [yarn classic](https://classic.yarnpkg.com) installed.
+2. Run `yarn install` to install dependencies for the test generator.
+3. Run `yarn gentest` in the `yoga` directory.
 
-### .NET
-.NET testing is not integrated in buck yet, you might need to set up .NET testing environment. We have a script which to launch C# test on macOS, `csharp/tests/Facebook.Yoga/test_macos.sh`.
+## Debugging
 
-## Benchmarks
-Benchmarks are located in `benchmark/YGBenchmark.c` and can be run with `buck run //benchmark:benchmark`. If you think your change has affected performance please run this before and after your change to validate that nothing has regressed. Benchmarks are run on every commit in CI.
-
-### JavaScript
-Installing through NPM
-```sh
-npm install yoga-layout
-```
-By default this will install the library and try to build for all platforms (node, browser asm, and standalone webpack). You may receive errors if you do not have the required platform development tools already installed. To preset the platform you'd like to build for you can set a .npmrc property first.
-```sh
-npm config set yoga-layout:platform standalone
-```
-This will now only run the standalone webpack build upon install.
-
-## Build Platforms
-
-| name           | description                                     |
-|----------------|-------------------------------------------------|
-| all (default)  | Builds all of these platforms.                  |
-| browser        | Builds asm js browser version.                  |
-| node           | Builds node js version.                         |
-| standalone     | Runs webpack.                                   |
-| none           | Does nothing. You can use the prepackaged libs. |
+Yoga provides a VSCode "launch.json" configuration which allows debugging unit tests. Simply add your breakpoints, and run "Debug C++ Unit tests (lldb)" (or "Debug C++ Unit tests (vsdbg)" on Windows).
