67 We provide compiled CSS and JS (`bootstrap.*`), as well as compiled and minified CSS and JS (`bootstrap.min.*`). CSS [source maps](https://developer.chrome.com/devtools/docs/css-preprocessors) (`bootstrap.*.map`) are available for use with certain browsers' developer tools.

70 ## Bugs and feature requests
72 Have a bug or a feature request? Please first read the [issue guidelines](https://github.com/twbs/bootstrap/blob/master/CONTRIBUTING.md#using-the-issue-tracker) and search for existing and closed issues. If your problem or idea is not addressed yet, [please open a new issue](https://github.com/twbs/bootstrap/issues/new).
74 Note that **feature requests must target [Bootstrap v4](https://github.com/twbs/bootstrap/tree/v4-dev),** because Bootstrap v3 is now in maintenance mode and is closed off to new features. This is so that we can focus our efforts on Bootstrap v4.
79 Bootstrap's documentation, included in this repo in the root directory, is built with [Jekyll](http://jekyllrb.com) and publicly hosted on GitHub Pages at <http://getbootstrap.com>. The docs may also be run locally.
81 ### Running documentation locally
83 1. If necessary, [install Jekyll](http://jekyllrb.com/docs/installation) and other Ruby dependencies with `bundle install`.
84 **Note for Windows users:** Read [this unofficial guide](http://jekyll-windows.juthilo.com/) to get Jekyll up and running without problems.
85 2. From the root `/bootstrap` directory, run `bundle exec jekyll serve` in the command line.
86 4. Open `http://localhost:9001` in your browser, and voilà.
88 Learn more about using Jekyll by reading its [documentation](http://jekyllrb.com/docs/home/).
90 ### Documentation for previous releases
92 Documentation for v2.3.2 has been made available for the time being at <http://getbootstrap.com/2.3.2/> while folks transition to Bootstrap 3.
94 [Previous releases](https://github.com/twbs/bootstrap/releases) and their documentation are also available for download.
99 Please read through our [contributing guidelines](https://github.com/twbs/bootstrap/blob/master/CONTRIBUTING.md). Included are directions for opening issues, coding standards, and notes on development.
101 Moreover, if your pull request contains JavaScript patches or features, you must include [relevant unit tests](https://github.com/twbs/bootstrap/tree/master/js/tests). All HTML and CSS should conform to the [Code Guide](https://github.com/mdo/code-guide), maintained by [Mark Otto](https://github.com/mdo).
103 **Bootstrap v3 is now closed off to new features.** It has gone into maintenance mode so that we can focus our efforts on [Bootstrap v4](https://github.com/twbs/bootstrap/tree/v4-dev), the future of the framework. Pull requests which add new features (rather than fix bugs) should target [Bootstrap v4 (the `v4-dev` git branch)](https://github.com/twbs/bootstrap/tree/v4-dev) instead.
105 Editor preferences are available in the [editor config](https://github.com/twbs/bootstrap/blob/master/.editorconfig) for easy use in common text editors. Read more and download plugins at <http://editorconfig.org>.

122 For transparency into our release cycle and in striving to maintain backward compatibility, Bootstrap is maintained under [the Semantic Versioning guidelines](http://semver.org/). Sometimes we screw up, but we'll adhere to those rules whenever possible.
