Contributions to Chart.js are welcome and encouraged, but please have a look through the guidelines in this document before raising an issue, or writing code for the project.
The [issue tracker](https://github.com/nnnick/Chart.js/issues) is the preferred channel for reporting bugs, requesting new features and submitting pull requests.
If you're suggesting a new chart type, please take a look at [writing new chart types](https://github.com/nnnick/Chart.js/blob/master/docs/06-Advanced.md#writing-new-chart-types) in the documentation, and some of the [community extensions](https://github.com/nnnick/Chart.js/blob/master/docs/06-Advanced.md#community-extensions) that have been created already.
To keep the library lightweight for everyone, it's unlikely we'll add many more chart types to the core of Chart.js, but issues are a good medium to design and spec out how new chart types could work and look.
Please do not use issues for support requests. For help using Chart.js, please take a look at the [`chartjs`](http://stackoverflow.com/questions/tagged/chartjs) tag on Stack Overflow.
Reporting bugs
--------------
Well structured, detailed bug reports are hugely valuable for the project.
Guidlines for reporting bugs:
- Check the issue search to see if it has already been reported
- Isolate the problem to a simple test case
- Provide a demonstration of the problem on [jsbin](http://jsbin.com) or similar
Please provide any additional details associated with the bug, if it's browser of screen density specific, or only happens with a certain configuration or data.
Pull requests
-------------
Clear, concise pull requests are excellent at continuing the projects community driven growth. But please review the guidelines below before starting work on the project.
Guidlines:
- Please ask before starting significant work on a pull request to check it's a change within the project scope, and isn't a duplicate effort
- Please make changes to the files in [`/src`](https://github.com/nnnick/Chart.js/tree/master/src), not `Chart.js` or `Chart.min.js` in the repo root directory
- Tabs for indentation, not spaces please.
- If adding new functionality, please also update the relevant `.md` file in [`/docs`](https://github.com/nnnick/Chart.js/tree/master/docs)
- Please make your commits in logical sections with clear commit messages
- Please avoid committing in the build Chart.js & Chart.min.js file, as it may cause conflicts when merging back
