+# Code of Conduct
+
+## 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

 ## 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.
+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`.
 
 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`.
 
-Instead of manually writing a test which ensures parity with web implementations of Flexbox you can run `gentest/gentest.rb` to generated a test for you. You can write html which you want to verify in Yoga, in `gentest/fixtures` folder, such as the following.

 .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`.
 
-## Code style
-For the main C implementation of Yoga clang-format is used to ensure a consistent code style. Please run `bash format.sh` before submitting a pull request. For other languages just try to follow the current code style.

 ## 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.

+## Maintainer Release Guide
 
+To publish a new release, follow these steps:
+
+1. Ensure you have your GPG key set up and your [OSS Sonatype](https://oss.sonatype.org/) credentials handy.
+2. Add the follow entries to either your local `gradle.properties` (don't forget to revert) or your global `~/.gradle/gradle.properties`:
+
+```
+# You get these from https://oss.sonatype.org/#profile;User%20Token
+mavenCentralRepositoryUsername=<username>
+mavenCentralRepositoryPassword=<password>
+
+# You can get the keyId (in GPG 1.4 format) by running `gpg1 --list-keys`.
+signing.secretKeyRingFile=</path/to/secring.gpg>
+signing.keyId=<key_id>
+signing.password=<key_password>
+```
+
+3. Change the `VERSION_NAME` in `gradle.properties` to a non-SNAPSHOT release.
+4. Commit and land the version change.
+5. Run `./gradlew publishToMaven`.
+6. Run `./gradlew closeAndReleaseRepository`.
+7. Change the `VERSION_NAME` in `gradle.properties` back to a new SNAPSHOT release.
+8. Commit and land the version change.
+9. Celebrate! You've made a release!
