Bundled JS files (`bootstrap.bundle.js` and minified `bootstrap.bundle.min.js`) include [Popper](https://github.com/floating-ui/popper-docs/blob/main/docs/v2/index.md).


            ## 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 [Astro](https://astro.build/) 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://docsearch.algolia.com/).


            ### Running documentation locally


            1. Run `npm install` to install the Node.js dependencies, including Astro (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 Astro by reading its [documentation](https://docs.astro.build/en/getting-started/).


            ### 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/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).


            Editor preferences are available in the [editor config](https://github.com/twbs/bootstrap/blob/main/.editorconfig) for easy use in common text editors. Read more and download plugins at <https://editorconfig.org/>.

            ## Versioning


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


            See [the Releases section of our GitHub project](https://github.com/twbs/bootstrap/releases) for changelogs for each release version of Bootstrap. Release announcement posts on [the official Bootstrap blog](https://blog.getbootstrap.com/) contain summaries of the most noteworthy changes made in each release.

	We provide compiled CSS and JS (`bootstrap.`), as well as compiled and minified CSS and JS (`bootstrap.min.`). [Source maps](https://web.dev/articles/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://github.com/floating-ui/popper-docs/blob/main/docs/v2/index.md).


	## 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 [Astro](https://astro.build/) 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://docsearch.algolia.com/).

	### Running documentation locally

	1. Run `npm install` to install the Node.js dependencies, including Astro (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 Astro by reading its [documentation](https://docs.astro.build/en/getting-started/).

	### 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/main/.github/CONTRIBUTING.md). Included are directions for opening issues, coding standards, and notes on development.

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.
