 ## 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.

 #### Pull Request Requirements

 CHIP considers there to be a few different types of pull requests:

 -   Trivial bug fix
 -   -   Decription 1
 -   -   Decription 2
 -   Small Bug fix
 -   -   Decription 1

 | ------------------- | -------------------------------------- | -------------- | ----------------------- | -------------- | --------------------- |

 | Small Bug fix       | 3 [approved reviewers](./REVIEWERS.md) |                |                         |                |                       |
 | Bug Fix             | 3 [approved reviewers](./REVIEWERS.md) |                |                         |                |                       |
 | Significiant Change | 3 [approved reviewers](./REVIEWERS.md) |                |                         |                |                       |
 | Feature             | 3 [approved reviewers](./REVIEWERS.md) |                |                         |                |                       |
 | Architecture Change | 3 [approved reviewers](./REVIEWERS.md) |                |                         |                |                       |

 Note: Where multiple reviewers are required, each reviewer must be from a
 different member company.

 #### 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.

 #### Merge Requirements

 -   Passes [Review Requirements](#review-requirements)
 -   [GitHub Workflows](.github/workflows) pass
 -   [Certification Tests](tests/certification/README.md) pass
 -   [Fuzz Tests](tests/fuzz/README.md) pass
 -   [Integration Tests](tests/integration/README.md) pass
 -   Linting passes
 -   Code style passes

 **When can I merge?** After these have been satisfied, any reviewer, or the
 originator can merge the PR into master.
