    21  ## Code of Conduct
    22  
    23  Please make sure to read and observe our [Code of Conduct](https://github.com/kubeedge/kubeedge/blob/master/CODE_OF_CONDUCT.md).
    24  
    25  ## Community Expectations
    26  
    27  KubeEdge is a community project driven by its community which strives to promote a healthy, friendly and productive environment.
    28  The goal of the community is to develop a cloud native edge computing platform built on top of Kubernetes to manage edge nodes and devices at scale and demonstrate resiliency, reliability in offline scenarios. To build a platform at such scale requires the support of a community with similar aspirations.
    29  
    30  - See [Community Membership](https://github.com/kubeedge/kubeedge/blob/master/docs/getting-started/community-membership.md) for a list of various community roles. With gradual contributions, one can move up in the chain.
    31  
    32  
    33  # Getting started
    34  
    35  - Fork the repository on GitHub
    36  - Read the [setup](https://github.com/kubeedge/kubeedge/blob/master/docs/setup/setup.md) for build instructions.
    37  
    38  
    39  # Your First Contribution
    40  
    41  We will help you to contribute in different areas like filing issues, developing features, fixing critical bugs and getting your work reviewed and merged.
    42  
    43  If you have questions about the development process, feel free to jump into our [Slack Channel](https://join.slack.com/t/kubeedge/shared_invite/enQtNjc0MTg2NTg2MTk0LWJmOTBmOGRkZWNhMTVkNGU1ZjkwNDY4MTY4YTAwNDAyMjRkMjdlMjIzYmMxODY1NGZjYzc4MWM5YmIxZjU1ZDI) or join our [mailing list](https://groups.google.com/forum/#!forum/kubeedge).
    44  
    45  ## Find something to work on
    46  
    47  We are always in need of help, be it fixing documentation, reporting bugs or writing some code.
    48  Look at places where you feel best coding practices aren't followed, code refactoring is needed or tests are missing.
    49  Here is how you get started.
    50  
    51  ### Find a good first topic
    52  
    53  There are [multiple repositories](https://github.com/kubeedge/) within the KubeEdge organization.
    54  Each repository has beginner-friendly issues that provide a good first issue.
    55  For example, [kubeedge/kubeedge](https://github.com/kubeedge/kubeedge) has [help wanted](https://github.com/kubeedge/kubeedge/issues?q=is%3Aopen+is%3Aissue+label%3A%22help+wanted%22) and [good first issue](https://github.com/kubeedge/kubeedge/issues?q=is%3Aopen+is%3Aissue+label%3A%22good+first+issue%22) labels for issues that should not need deep knowledge of the system.
    56  We can help new contributors who wish to work on such issues.
    57  
    58  Another good way to contribute is to find a documentation improvement, such as a missing/broken link. Please see [Contributing](#contributing) below for the workflow.
    59  
    60  #### Work on an issue
    61  
    62  When you are willing to take on an issue, you can assign it to yourself. Just reply with `/assign` or `/assign @yourself` on an issue,
    63  then the robot will assign the issue to you and your name will present at `Assignees` list.
    64  
    65  ### File an Issue
    66  
    67  While we encourage everyone to contribute code, it is also appreciated when someone reports an issue.
    68  Issues should be filed under the appropriate KubeEdge sub-repository.
    69  
    70  *Example:* a KubeEdge issue should be opened to [kubeedge/kubeedge](https://github.com/kubeedge/kubeedge/issues).
    71  
    72  Please follow the prompted submission guidelines while opening an issue.
    73  
    74  # Contributor Workflow
    75  
    76  Please do not ever hesitate to ask a question or send a pull request.
    77  
    78  This is a rough outline of what a contributor's workflow looks like:
    79  
    80  - Create a topic branch from where to base the contribution. This is usually master.
    81  - Make commits of logical units.
    82  - Make sure commit messages are in the proper format (see below).
    83  - Push changes in a topic branch to a personal fork of the repository.
    84  - Submit a pull request to [kubeedge/kubeedge](https://github.com/kubeedge/kubeedge).
    85  - The PR must receive an approval from two maintainers.
    86  
    87  ## Creating Pull Requests
    88  
    89  Pull requests are often called simply "PR".
    90  KubeEdge generally follows the standard [github pull request](https://help.github.com/articles/about-pull-requests/) process.
    91  To submit a proposed change, please develop the code/fix and add new test cases.
    92  After that, run these local verifications before submitting pull request to predict the pass or
    93  fail of continuous integration.
    94  
    95  * Run and pass `make verify`
    96  * Run and pass `make edge_test` or `make cloud_test`
    97  * Run and pass `make edge_integration_test`
    98  
    99  In addition to the above process, a bot will begin applying structured labels to your PR.
   100  
   101  The bot may also make some helpful suggestions for commands to run in your PR to facilitate review.
   102  These `/command` options can be entered in comments to trigger auto-labeling and notifications.
   103  Refer to its [command reference documentation](https://go.k8s.io/bot-commands).
   104  
   105  ## Code Review
   106  
   107  To make it easier for your PR to receive reviews, consider the reviewers will need you to:
   108  
   109  * follow [good coding guidelines](https://github.com/golang/go/wiki/CodeReviewComments).
   110  * write [good commit messages](https://chris.beams.io/posts/git-commit/).
   111  * break large changes into a logical series of smaller patches which individually make easily understandable changes, and in aggregate solve a broader issue.
   112  * label PRs with appropriate reviewers: to do this read the messages the bot sends you to guide you through the PR process.
   113  
   114  ### Format of the commit message
   115  
   116  We follow a rough convention for commit messages that is designed to answer two questions: what changed and why.
   117  The subject line should feature the what and the body of the commit should describe the why.
   118  
   119  ```
   120  scripts: add test codes for metamanager
   121  
   122  this add some unit test codes to imporve code coverage for metamanager
   123  
   124  Fixes #12
   125  ```
   126  
   127  The format can be described more formally as follows:
   128  
   129  ```
   130  <subsystem>: <what changed>
   131  <BLANK LINE>
   132  <why this change was made>
   133  <BLANK LINE>
   134  <footer>
   135  ```
   136  
   137  The first line is the subject and should be no longer than 70 characters, the second line is always blank, and other lines should be wrapped at 80 characters. This allows the message to be easier to read on GitHub as well as in various git tools.
   138  
   139  Note: if your pull request isn't getting enough attention, you can use the reach out on Slack to get help finding reviewers.
   140  
   141  ## Testing
   142  
   143  There are multiple types of tests.
   144  The location of the test code varies with type, as do the specifics of the environment needed to successfully run the test:
   145  
   146  * Unit: These confirm that a particular function behaves as intended. Unit test source code can be found adjacent to the corresponding source code within a given package. These are easily run locally by any developer.
   147  * Integration: These tests cover interactions of package components or interactions between KubeEdge components and Kubernetes control plane components like API server.  An example would be testing whether the device controller is able to create config maps when device CRDs are created in the API server.
   148  * End-to-end ("e2e"): These are broad tests of overall system behavior and coherence. The e2e tests are in [kubeedge e2e](https://github.com/kubeedge/kubeedge/tree/master/tests/e2e).
   149  
   150  Continuous integration will run these tests on PRs.
