We provide compiled CSS and JS (`bootstrap.*`), as well as compiled and minified CSS and JS (`bootstrap.min.*`). [Source maps](https://developers.google.com/web/tools/chrome-devtools/javascript/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](https://popper.js.org/). ## Bugs and feature requests Have a bug or a feature request? Please first read the [issue guidelines](https://github.com/twbs/bootstrap/blob/main/.github/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/choose). ## Documentation Bootstrap's documentation, included in this repo in the root directory, is built with [Hugo](https://gohugo.io/) and publicly hosted on GitHub Pages at . The docs may also be run locally. Documentation search is powered by [Algolia's DocSearch](https://docsearch.algolia.com/). ### Running documentation locally 1. Run `npm install` to install the Node.js dependencies, including Hugo (the site builder). 2. Run `npm run test` (or a specific npm script) to rebuild distributed CSS and JavaScript files, as well as our docs assets. 3. From the root `/bootstrap` directory, run `npm run docs-serve` in the command line. 4. Open `http://localhost:9001/` in your browser, and voilà. Learn more about using Hugo by reading its [documentation](https://gohugo.io/documentation/). ### Documentation for previous releases You can find all our previous releases docs on . [Previous releases](https://github.com/twbs/bootstrap/releases) and their documentation are also available for download. ## Contributing Please read through our [contributing guidelines](https://github.com/twbs/bootstrap/blob/main/.github/CONTRIBUTING.md). Included are directions for opening issues, coding standards, and notes on development. Moreover, if your pull request contains JavaScript patches or features, you must include [relevant unit tests](https://github.com/twbs/bootstrap/tree/main/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).
