We'd love for you to contribute to our source code and to make Material Design Lite even better than it is today! Here are the guidelines we'd like you to follow:
- [Code of Conduct](#coc)
- [Question or Problem?](#question)
- [Issues and Bugs](#issue)
- [Feature Requests](#feature)
- [Submission Guidelines](#submit)
- [Coding Rules](#rules)
- [Signing the CLA](#cla)
## <a name="coc"></a> Code of Conduct
As contributors and maintainers of the Material Design Lite project, we pledge to respect everyone who contributes by posting issues, updating documentation, submitting pull requests, providing feedback in comments, and any other activities.
Communication through any of Material Design Lite's channels (GitHub, StackOverflow, Google+, Twitter, etc.) must be constructive and never resort to personal attacks, trolling, public or private harrassment, insults, or other unprofessional conduct.
We promise to extend courtesy and respect to everyone involved in this project regardless of gender, gender identity, sexual orientation, disability, age, race, ethnicity, religion, or level of experience. We expect anyone contributing to the Material Design Lite project to do the same.
If any member of the community violates this code of conduct, the maintainers of the Material Design Lite project may take action, removing issues, comments, and PRs or blocking accounts as deemed appropriate.
If you are subject to or witness unacceptable behavior, or have any other concerns, please drop us a line at addyo@google.com.
## <a name="question"></a> Got a Question or Problem?
If you have questions about how to use Material Design Lite, please direct these to [StackOverflow][stackoverflow] and use the `material-design-lite` tag. We are also available on GitHub issues.
## <a name="issue"></a> Found an Issue?
If you find a bug in the source code or a mistake in the documentation, you can help us by
submitting an issue to our [GitHub Repository][github]. Even better you can submit a Pull Request
with a fix.
## <a name="feature"></a> Want a Feature?
You can request a new feature by submitting an issue to our [GitHub Repository][github]. If you
would like to implement a new feature then consider what kind of change it is:
* **Major Changes** that you wish to contribute to the project should be discussed first on our
[issue tracker][github] so that we can better coordinate our efforts, prevent
duplication of work, and help you to craft the change so that it is successfully accepted into the
project.
* **Small Changes** can be crafted and submitted to the [GitHub Repository][github] as a Pull Request.
*[Website](https://developers.google.com/web/mdl/) related issues should be filed on the [Web Fundamentals](https://github.com/google/WebFundamentals/issues/new) issue tracker.*
## <a name="submit"></a> Submission Guidelines
### Submitting an Issue
Before you submit your issue search the archive, maybe your question was already answered.
If your issue appears to be a bug, and hasn't been reported, open a new issue.
Help us to maximize the effort we can spend fixing issues and adding new
features, by not reporting duplicate issues. Providing the following information will increase the
chances of your issue being dealt with quickly:
* **Overview of the Issue** - if an error is being thrown a non-minified stack trace helps
* **Motivation for or Use Case** - explain why this is a bug for you
* **Material Design Lite Version(s)** - is it a regression?
* **Browsers and Operating System** - is this a problem with all browsers or only IE9?
* **Reproduce the Error** - provide a live example (using JSBin) or a unambiguous set of steps.
* **Related Issues** - has a similar issue been reported before?
* **Suggest a Fix** - if you can't fix the bug yourself, perhaps you can point to what might be
causing the problem (line of code or commit)
**If you get help, help others. Good karma rulez!**
### Submitting a Pull Request
Before you submit your pull request consider the following guidelines:
* Search [GitHub](https://github.com/google/material-design-lite/pulls) for an open or closed Pull Request
that relates to your submission. You don't want to duplicate effort.
* Please sign our [Contributor License Agreement (CLA)](#cla) before sending pull
requests. We cannot accept code without this.
* Make your changes in a new git branch:
```shell
git checkout -b my-fix-branch master
```
* Create your patch, **including appropriate test cases**.
* Follow our [Coding Rules](#rules).
* Run the full Material Design Lite test suite (`gulp test`),
and ensure that all tests pass.
* Avoid checking in files that shouldn't be tracked (e.g `node_modules`, `gulp-cache`, `.tmp`, `.idea`). We recommend using a [global](#global-gitignore) gitignore for this.
* Make sure **not** to include a recompiled version of the files found in `/css` and `/js` as part of your PR. We will generate these automatically.
* Commit your changes using a descriptive commit message.
```shell
git commit -a
```
Note: the optional commit `-a` command line option will automatically "add" and "rm" edited files.
* Build your changes locally to ensure all the tests pass:
```shell
gulp
```
* Push your branch to GitHub:
```shell
git push origin my-fix-branch
```
* In GitHub, send a pull request to `material-design-lite:master`.
* If we suggest changes then:
* Make the required updates.
* Re-run the Material Design Lite test suite to ensure tests are still passing.
* Rebase your branch and force push to your GitHub repository (this will update your Pull Request):
```shell
git rebase master -i
git push origin my-fix-branch -f
```
That's it! Thank you for your contribution!
#### After your pull request is merged
After your pull request is merged, you can safely delete your branch and pull the changes
from the main (upstream) repository:
* Delete the remote branch on GitHub either through the GitHub web UI or your local shell as follows:
```shell
git push origin --delete my-fix-branch
```
* Check out the master branch:
```shell
git checkout master -f
```
* Delete the local branch:
```shell
git branch -D my-fix-branch
```
* Update your master with the latest upstream version:
```shell
git pull --ff upstream master
```
## <a name="rules"></a> Coding Rules
We generally follow the [Google JavaScript style guide](js-style-guide) with a few minor exceptions documented in our
[JSCS configuration.](jscs-config).
[JSCS](http://jscs.info) is a tool for linting code against a style guide and has plugins available for both editors and build tools. Should
you find that you would prefer to automatically format your code to match our style guide, you can use the JSCS [autoformatting](autoformatting)
feature.
## <a name="cla"></a> Signing the CLA
Please sign our Contributor License Agreement (CLA) before sending pull requests. For any code
changes to be accepted, the CLA must be signed. It's a quick process, we promise!
* For individuals we have a [simple click-through form][individual-cla].
* For corporations we'll need you to
[print, sign and one of scan+email, fax or mail the form][corporate-cla].
