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/), but not [jQuery](https://jquery.com/).
## Bugs and feature requests
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).
## Documentation
Bootstrap's documentation, included in this repo in the root directory, is built with [Jekyll](https://jekyllrb.com/) 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](https://community.algolia.com/docsearch/). Working on our search? Be sure to set `debug: true` in `site/docs/4.5/assets/js/src/search.js` file.
### Running documentation locally
1. Run through the [tooling setup](https://getbootstrap.com/docs/4.5/getting-started/build-tools/#tooling-setup) to install Jekyll (the site builder) and other Ruby dependencies with `bundle install`.
2. Run `npm install` to install Node.js dependencies.
3. Run `npm start` to compile CSS and JavaScript files, generate our docs, and watch for changes.
4. Open `http://localhost:9001` in your browser, and voilà.
Learn more about using Jekyll by reading its [documentation](https://jekyllrb.com/docs/).
### Documentation for previous releases
You can find all our previous releases docs on <https://getbootstrap.com/docs/versions/>.
[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/master/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/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).

Release announcement posts on [the official Bootstrap blog](https://blog.getbootstrap.com/) contain summaries of the most noteworthy changes made in each release.
