How to contribute to Backbone.js

Before you open a ticket or send a pull request, search for previous discussions about the same feature or issue. Add to the earlier ticket if you find one.
Before sending a pull request for a feature or bug fix, be sure to have tests.
If your pull request affects Backbone's public API, make relevant changes to the documentation. If appropriate, also add a line in the "Change Log" section.
Use the same coding style as the rest of the codebase.
In your pull request, do not re-build the minified backbone-min.js file. We'll do that before cutting a new release.
All pull requests should be made to master. If the patch is for documentation of the currently released version, please note this so that it can be cherry picked into gh-pages.
