Bugs and feature requests
Have a bug or a feature request? Please open a new issue. Before opening any issue, please search for existing issues and read the Issue Guidelines, written by Nicolas Gallagher.
Documentation
Bootstrap's documentation, included in this repo in the root directory, is built with Jekyll and publicly hosted on GitHub Pages at http://getbootstrap.com. The docs may also be run locally.
Running documentation locally
- If necessary, install Jekyll (requires v1.x).
- From the
/bootstrapdirectory, runjekyll servein the command line. - Open http://localhost:9001 in your browser, and voilà.
Learn more about using Jekyll by reading their documentation.
Documentation for previous releases
Documentation for v2.3.2 has been made available for the time being at http://getbootstrap.com/2.3.2/docs while folks transition to Bootstrap 3.
Previous releases and their documentation are also available for download.
Compiling CSS and JavaScript
Bootstrap includes a makefile with convenient methods for working with the framework. Before getting started, install the necessary local dependencies:
$ npm install
When completed, you'll be able to run the various make commands provided.
Available makefile commands
Build - make
make runs the Recess compiler to rebuild the /less files and compile the docs. Requires recess and uglify-js.
Compile CSS, JS, and fonts - make bootstrap
make bootstrap creates the /bootstrap directory with compiled files. Requires recess and uglify-js.
Tests - make test
Runs jshint and qunit tests headlessly in phantomjs (used for ci). Requires phantomjs.
Watch - make watch
This is a convenience method for watching just Less files and automatically building them whenever you save. Requires the watchr gem.
Troubleshooting dependencies
Should you encounter problems with installing dependencies or running makefile commands, uninstall all previous dependency versions (global and local). Then, rerun npm install.
Contributing
Please read through our guidelines for contributing to Bootstrap. Included are directions for opening issues, coding standards, and notes on development.
More over, if your pull request contains JavaScript patches or features, you must include relevant unit tests. All HTML and CSS should conform to the Code Guide, maintained by Mark Otto.
Editor preferences are available in the editor config for easy use in common text editors. Read more and download plugins at http://editorconfig.org.

Versioning
For transparency and insight into our release cycle, and for striving to maintain backward compatibility, Bootstrap will be maintained under the Semantic Versioning guidelines as much as possible.
Releases will be numbered with the following format:
<major>.<minor>.<patch>
And constructed with the following guidelines:
- Breaking backward compatibility bumps the major (and resets the minor and patch)
- New additions without breaking backward compatibility bumps the minor (and resets the patch)
- Bug fixes and misc changes bumps the patch
