-# Contributor Covenant Code of Conduct
+# Code of Conduct
 
-## Our Pledge
+The code of conduct for this project can be found at https://swift.org/code-of-conduct.
 
-In the interest of fostering an open and welcoming environment, we as
-contributors and maintainers pledge to making 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 both within project spaces and in public spaces
-when an individual is representing the project or its community. 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 swifttracing@slashmo.codes. 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.

+## Legal
+
+By submitting a pull request, you represent that you have the right to license
+your contribution to Apple and the community, and agree by submitting the patch
+that your contributions are licensed under the Apache 2.0 license (see
+`LICENSE.txt`).
+
+## How to submit a bug report
+
+Please ensure to specify the following:
+
+* Swift Distributed Tracing Baggage commit hash
+* Contextual information (e.g. what you were trying to achieve with Swift Distributed Tracing Baggage)
+* Simplest possible steps to reproduce
+    * More complex the steps are, lower the priority will be.
+    * A pull request with failing test case is preferred, but it's just fine to paste the test case into the issue description.
+* Anything that might be relevant in your opinion, such as:
+    * Swift version or the output of `swift --version`
+    * OS version and the output of `uname -a`
+    * Network configuration
+
+### Example
+
+ ```
+ Commit hash: b17a8a9f0f814c01a56977680cb68d8a779c951f
+ Context:
+ While testing my application that uses with Swift Distributed Tracing Baggage, I noticed that ...
+ Steps to reproduce:
+ 1. ...
+ 2. ...
+ 3. ...
+ 4. ...
+ $ swift --version
+ Swift version 4.0.2 (swift-4.0.2-RELEASE)
+ Target: x86_64-unknown-linux-gnu
+ Operating system: Ubuntu Linux 16.04 64-bit
+ $ uname -a
+ Linux beefy.machine 4.4.0-101-generic #124-Ubuntu SMP Fri Nov 10 18:29:59 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux
+ My system has IPv6 disabled.
+ ```
+
+## Writing a Patch
+
+A good patch is:
+
+1. Concise, and contains as few changes as needed to achieve the end result.
+2. Tested, ensuring that any tests provided failed before the patch and pass after it.
+3. Documented, adding API documentation as needed to cover new functions and properties.
+4. Accompanied by a great commit message, using our commit message template.
+
+### Commit Message Template
+
+We require that your commit messages match our template. The easiest way to do that is to get git to help you by explicitly using the template. To do that, `cd` to the root of our repository and run:
+
+     git config commit.template dev/git.commit.template
+
+### Run `./scripts/soundness.sh`
+
+The scripts directory contains a [soundness.sh script](https://github.com/apple/swift-distributed-tracing-baggage/blob/main/scripts/soundness.sh)
+that enforces additional checks, like license headers and formatting style.
+
+Please make sure to `./scripts/soundness.sh` before pushing a change upstream, otherwise it is likely the PR validation will fail
+on minor changes such as a missing `self.` or similar formatting issues.
+
+> The script also executes the above mentioned `generate_linux_tests.rb`.
+For frequent contributors, we recommend adding the script as a [git pre-push hook](https://git-scm.com/book/en/v2/Customizing-Git-Git-Hooks), which you can do via executing the following command in the project root directory:
+
+ ```bash
+ cat << EOF > .git/hooks/pre-push
+ #!/bin/bash
+ if [[ -f "scripts/soundness.sh" ]]; then
+   scripts/soundness.sh
+ fi
+ EOF
+ ```
+
+Which makes the script execute, and only allow the `git push` to complete if the check has passed.
+
+In the case of formatting issues, you can then `git add` the formatting changes, and attempt the push again.
+
+## How to contribute your work
+
+Please open a pull request at https://github.com/apple/swift-distributed-tracing-baggage. Make sure the CI passes, and then wait for code review.
