* jQuery Core API documentation issues can be filed [at the API repo](http://github.com/jquery/api.jquery.com/issues).

* Bugs or suggestions for other jQuery Foundation projects should be filed in [their respective repos](http://github.com/jquery/).

More information on how to contribute to this and other jQuery Foundation projects is at [contribute.jquery.org](http://contribute.jquery.org), including a short guide with tips, tricks, and ideas on [getting started with open source](http://contribute.jquery.org/open-source/). Please review our [commit & pull request guide](http://contribute.jquery.org/commits-and-pull-requests/) and [style guides](http://contribute.jquery.org/style-guide/) for instructions on how to maintain a fork and submit patches. Before we can merge any pull request, we'll also need you to sign our [contributor license agreement](http://contribute.jquery.org/cla/).

jQuery is so popular that many developers have knowledge of its capabilities and limitations. Most questions about using jQuery can be answered on popular forums such as [Stack Overflow](http://stackoverflow.com). Please start there when you have questions, even if you think you've found a bug.

The jQuery Core team watches the [jQuery Development Forum](http://forum.jquery.com/developing-jquery-core). If you have longer posts or questions that can't be answered in places such as Stack Overflow, please feel free to post them there. If you think you've found a bug, please [file it in the bug tracker](#how-to-report-bugs). The Core team can be found in the [#jquery-dev](http://webchat.freenode.net/?channels=jquery-dev) IRC channel on irc.freenode.net.

The jQuery Core team has a weekly meeting to discuss the progress of current work. The meeting is held in the [#jquery-meeting](http://webchat.freenode.net/?channels=jquery-meeting) IRC channel on irc.freenode.net at [Noon EST](http://www.timeanddate.com/worldclock/fixedtime.html?month=1&day=17&year=2011&hour=12&min=0&sec=0&p1=43) on Mondays.

[jQuery Core Meeting Notes](http://meetings.jquery.org/category/core/)

Ask for help first in the [Using jQuery Forum](http://forum.jquery.com/using-jquery) or another discussion forum like [Stack Overflow](http://stackoverflow.com/). You will get much quicker support, and you will help avoid tying up the jQuery team with invalid bug reports.

Bugs in old versions of jQuery may have already been fixed. In order to avoid reporting known issues, make sure you are always testing against the [latest build](http://code.jquery.com/jquery.js). We cannot fix bugs in older released files, if a bug has been fixed in a subsequent version of jQuery the site should upgrade.

When experiencing a problem, [reduce your code](http://webkit.org/quality/reduction.html) to the bare minimum required to reproduce the issue. This makes it *much* easier to isolate and fix the offending code. Bugs reported without reduced test cases take on average 9001% longer to fix than bugs that are submitted with them, so you really should try to do this if at all possible.

Remember that jQuery supports multiple browsers and their versions; any contributed code must work in all of them. You can refer to the [browser support page](http://jquery.com/browser-support/) for the current list of supported browsers.

- [Browser support](http://jquery.com/browser-support/) differs between the master branch and the compat branch. Specifically, the master branch does not support legacy browsers such as IE8. The jQuery team continues to provide support for legacy browsers on the compat branch. Use the latest compat release if support for those browsers is required. See [browser support](http://jquery.com/browser-support/) for more info.

For Windows, you have to download and install [git](http://git-scm.com/downloads) and [Node.js](http://nodejs.org/download/).
