| ## Bugs |
| |
| If you find a bug in the source code, you can help us by [submitting a GitHub Issue](https://github.com/project-chip/connectedhomeip/issues/new). The best bug reports provide a detailed description of the issue and step-by-step instructions for predictably reproducing the issue. Even better, you can [submit a Pull Request](#submitting-a-pull-request) with a fix. |
| |
| ## New Features |
| |
| You can request a new feature by [submitting a GitHub Issue](https://github.com/project-chip/connectedhomeip/issues/new). |
| |
| If you would like to implement a new feature, please consider the scope of the new feature: |
| |
| * *Large feature*: first [submit a GitHub |
| Issue](https://github.com/project-chip/connectedhomeip/issues/new) and communicate |
| your proposal so that the community can review and provide feedback. Getting |
| early feedback will help ensure your implementation work is accepted by the |
| community. This will also allow us to better coordinate our efforts and |
| minimize duplicated effort. |
| |
| * *Small feature*: can be implemented and directly [submitted as a Pull |
| Request](#submitting-a-pull-request). |
| |
| ## Contributing Code |
| |
| CHIP follows the "Fork-and-Pull" model for accepting contributions. |
| |
| ### Initial Setup |
| |
| Setup your GitHub fork and continuous-integration services: |
| |
| 1. Fork the [CHIP |
| repository](https://github.com/project-chip/connectedhomeip) by clicking "Fork" |
| on the web UI. |
| |
| 2. All contributions must pass all checks and reviews to be accepted. |
| |
| Setup your local development environment: |
| |
| ```bash |
| # Clone your fork |
| git clone git@github.com:<username>/connectedhomeip.git |
| |
| # Configure upstream alias |
| git remote add upstream git@github.com:project-chip/connectedhomeip.git |
| ``` |
| |
| ### Submitting a Pull Request |
| |
| #### Branch |
| |
| For each new feature, create a working branch: |
| |
| ```bash |
| # Create a working branch for your new feature |
| git branch --track <branch-name> origin/master |
| |
| # Checkout the branch |
| git checkout <branch-name> |
| ``` |
| |
| #### Create Commits |
| |
| ```bash |
| # Add each modified file you'd like to include in the commit |
| git add <file1> <file2> |
| |
| # Create a commit |
| git commit |
| ``` |
| |
| This will open up a text editor where you can craft your commit message. |
| |
| #### Upstream Sync and Clean Up |
| |
| Prior to submitting your pull request, you might want to do a few things to |
| clean up your branch and make it as simple as possible for the original |
| repository's maintainer to test, accept, and merge your work. |
| |
| If any commits have been made to the upstream master branch, you should rebase |
| your development branch so that merging it will be a simple fast-forward that |
| won't require any conflict resolution work. |
| |
| ```bash |
| # Fetch upstream master and merge with your repository's master branch |
| git checkout master |
| git pull upstream master |
| |
| # If there were any new commits, rebase your development branch |
| git checkout <branch-name> |
| git rebase master |
| ``` |
| |
| Now, it may be desirable to squash some of your smaller commits down into a |
| small number of larger more cohesive commits. You can do this with an |
| interactive rebase: |
| |
| ```bash |
| # Rebase all commits on your development branch |
| git checkout |
| git rebase -i master |
| ``` |
| |
| This will open up a text editor where you can specify which commits to squash. |
| |
| |
| #### Push and Test |
| |
| ```bash |
| # Checkout your branch |
| git checkout <branch-name> |
| |
| # Push to your GitHub fork: |
| git push origin <branch-name> |
| ``` |
| |
| This will trigger the continuous-integration checks. You |
| can view the results in the respective services. Note that the integration |
| checks will report failures on occasion. |
| |

| ### Prior to review, all changes require: |
| - [GitHub Workflows](../.github/workflows) pass |
| - [Certification Tests](tests/certification/README.md) pass |
| - [Unit Tests](tests/unit/README.md) pass |
| - [Fuzz Tests](tests/fuzz/README.md) pass |
| - [Integration Tests](tests/integration/README.md) pass |
| - Linting passes |
| - Code style passes |
| |
| Each type of change has unique additional requirements, here's a table of those: |
| | Type | Reviewer Requirements | New Unit Tests | New Certification Tests | New Fuzz Tests | New Integration Tests | |
| |----|----|----|----|----|----| |

| #### Submit Pull Request |
| |
| Once you've validated the CI results, go to the page for |
| your fork on GitHub, select your development branch, and click the pull request |
| button. If you need to make any adjustments to your pull request, just push the |
| updates to GitHub. Your pull request will automatically track the changes on |
| your development branch and update. |
| |
| #### Code reviews |
| |
| All submissions, including submissions by project members, require 3 reviews to be accepted from different member companies. |
| |
| #### Merge Requirements |
