We provide compiled CSS and JS (bootstrap.*), as well as compiled and minified CSS and JS (bootstrap.min.*). Source maps (bootstrap.*.map) are available for use with certain browsers' developer tools. Bundled JS files (bootstrap.bundle.js and minified bootstrap.bundle.min.js) include Popper, but not jQuery.

Bootstrap's documentation, included in this repo in the root directory, is built with Hugo and publicly hosted on GitHub Pages at https://getbootstrap.com/. The docs may also be run locally.
Documentation search is powered by Algolia's DocSearch. Working on our search? Be sure to set debug: true in site/assets/js/search.js.
