[GitHub Issues](https://github.com/videojs/video.js/issues) are used for all discussions around the codebase, including **bugs**, **features**, and other **enhancements**.
3. Isolate the problem —**create a [reduced test case](http://css-tricks.com/6263-reduced-test-cases/)** with a live example. You can possibly use [this JSBin example](http://jsbin.com/axedog/7/edit) as a starting point.

### Requesting a Feature
1. [Check the plugin list](https://github.com/videojs/video.js/wiki/Plugins) for any plugins that may already support the feature.
2. [Search the issues](https://github.com/videojs/video.js/issues) for any previous requests for the same feature, and give a thumbs up or +1 on existing requests.
2. If no previous requests exist, create a new issue. Please be as clear as possible about why the feautre is needed and the intended use case.

Contributing code
-----------------
To contibute code you'll need to be able to build a copy of Video.js and run tests locally. There are a few requirements before getting started.
- Node.js -- Video.js uses Node for build and test automation. Node is available for Windows, Mac OS X, Linux, and SunOS, as well as source code if that doesn't scare you. [Download and install Node.js](http://nodejs.org/download/)
On Unix-based systems, you'll have to do this as a superuser:
```bash
sudo npm install -g grunt-cli
```
On Windows, you can just run:
```bash
npm install -g grunt-cli
```
- Contribflow -- A homegrown git workflow tool for managing feature/hotfix branches and submitting pull requests. If you have your own preferred git workflow, contribflow isn't required, but the following instructions will assume you're using it.
On Unix-based systems, you'll have to do this as a superuser:
First, [fork](http://help.github.com/fork-a-repo/) the video.js git repository. At the top of every github page, there is a Fork button. Click it, and the forking process will copy Video.js into your own GitHub account.
Clone your fork of the repo into your code directory
Install the required node.js modules using node package manager
```bash
npm install
```
> A note to Windows developers: If you run npm commands, and you find that your command prompt colors have suddenly reversed, you can configure npm to set color to false to prevent this from happening.
> `npm config set color false`
> Note that this change takes effect when a new command prompt window is opened; the current window will not be affected.
Video.js is also configured to run tests with Karma. Karma is installed as a grunt plugin to run QUnit tests in real browsers, as opposed to simply running the tests in phantomjs, a headless browser. To run the tests with Karma:
At this point you should have a built copy of video.js in a directory named `dist`, and all tests should be passing.
### Making Changes
Whether you're adding something new, making something better, or fixing a bug, you'll first want to search the [GitHub issues](https://github.com/videojs/video.js/issues) and [plugins list](https://github.com/videojs/video.js/wiki/Plugins) to make sure you're aware of any previous discussion or work. If an unclaimed issue exists, claim it via a comment. If no issue exists for your change, submit one, follwing the [issue filing guidelines](#filing-issues).
There are two categories of changes in video.js land, features and hotfixes (Video.js follows a branching model similar to [gitflow](http://nvie.com/posts/a-successful-git-branching-model/)). Hotfixes are for urgent fixes that need to be released immediately as a patch. Features are for everything else (including non-urgent fixes). If you think you have a hotfix scenario, verify that (via comment) before starting the work. We'll focus on features here, but you can swap `hotfix` for `feature` in any command.
Start a new development branch
```bash
contrib feature start
```
You'll be prompted to name the branch. After that, contrib will create the branch locally, and use git to push it up to your origin, and track it. You're now ready to start building your feature or fixing that bug! Be sure to read the [Code Style Guide](#code-style-guide).
While you're developing, you can ensure your changes are working by writing tests (in the `test` directory) and running `grunt test`.
There's also a sandbox directory where you can add any file and it won't get tracked as a change. To start you can copy the example index file and see a working version of a player (using the local source code) by loading it in a browser.
> 2. [Disable the version of Flash included with Chrome](http://helpx.adobe.com/flash-player/kb/flash-player-google-chrome.html#How_can_I_run_debugger_or_alternate_versions_of_Flash_Player_in_Google_Chrome) and enable a system-wide version of Flash instead.
Commit and push changes as you go (using git directly). Write thorough descriptions of your changes in your commit messages.
```bash
git add .
git commit -av
git push
```
> GitHub allows you to close an issue through your commit message using the [fixes](https://github.com/blog/831-issues-2-0-the-next-generation) keyword.
>
> ```bash
> My commit message. fixes #123
> Testing: (briefly describe any testing here, for example, 'unit tests and cross-browser manual tests around playback and network interruption')
> ```
### Submitting your changes
First, thoroughly test your feature or fix, including writing tests to make sure your change doesn't get regressed in a future update. If you're fixing a bug, we recommend in addition to testing the fix itself, to do some testing around the areas that your fix has touched. For example, a brief smoketest of the player never hurts.
Make sure your changes are pushed to origin
```bash
git push
```
Use contrib to submit a a pull request (make sure you're in your feature branch)
```bash
contrib feature submit
```
You'll be prompted for title and description for the Pull Request. After that, contrib will use Git to submit your pull request to video.js.
You're Done! (except for cleanup.) To clean up your feature or hotfix branch:
First, checkout your feature or issue branch:
```bash
git checkout (branchname)
```
Run this command to clean up your feature:
```bash
contrib feature delete
```
Run this command to clean up your bug fix:
```bash
contrib hotfix delete
```
> PLEASE NOTE: THIS WILL DELETE YOUR LOCAL AND REMOTE COPIES OF THE FEATURE.
> This is meant to clean up your local and remote branches, so make sure any changes you don't want to lose have been pulled into the parent project or another branch first.
Please follow [Google's JavaScript Style Guide](http://google-styleguide.googlecode.com/svn/trunk/javascriptguide.xml) to the letter. If your editor supports [.editorconfig](http://editorconfig.org/#download) it will make it easier to manage differences from your own coding style.
### Style examples include:
* Two space indents.
* Delimit strings with single-quotes `'`, not double-quotes `"`.
* No trailing whitespace, except in markdown files where a linebreak must be forced.
* No more than [one assignment](http://benalman.com/news/2012/05/multiple-var-statements-javascript/) per `var` statement.
* Prefer `if` and `else` to ["clever"](http://programmers.stackexchange.com/a/25281) uses of `? :` conditional or `||`, `&&` logical operators.
* **When in doubt, follow the conventions you see used in the source already.**
If you happen to find something in the codebase that does not follow the style guide, that's a good opportunity to make your first contribution!
