+
+
+## What's included
+
+Within the download you'll find the following directories and files, logically grouping common assets and providing both compiled and minified variations. You'll see something like this:
+
+```text
+bootstrap/
+└── dist/
+ ├── css/
+ │ ├── bootstrap-grid.css
+ │ ├── bootstrap-grid.css.map
+ │ ├── bootstrap-grid.min.css
+ │ ├── bootstrap-grid.min.css.map
+ │ ├── bootstrap-reboot.css
+ │ ├── bootstrap-reboot.css.map
+ │ ├── bootstrap-reboot.min.css
+ │ ├── bootstrap-reboot.min.css.map
+ │ ├── bootstrap.css
+ │ ├── bootstrap.css.map
+ │ ├── bootstrap.min.css
+ │ └── bootstrap.min.css.map

+ ├── bootstrap.bundle.min.js.map
+ ├── bootstrap.js
+ ├── bootstrap.js.map
+ ├── bootstrap.min.js
+ └── bootstrap.min.js.map
+```
+
+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).
+
+Editor preferences are available in the [editor config](https://github.com/twbs/bootstrap/blob/master/.editorconfig) for easy use in common text editors. Read more and download plugins at <https://editorconfig.org/>.
+
+
+## Community
+
+Get updates on Bootstrap's development and chat with the project maintainers and community members.

+- Developers should use the keyword `bootstrap` on packages which modify or add to the functionality of Bootstrap when distributing through [npm](https://www.npmjs.com/browse/keyword/bootstrap) or similar delivery mechanisms for maximum discoverability.
+
+
+## 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.
+Thanks to [BrowserStack](https://www.browserstack.com/) for providing the infrastructure that allows us to test in real browsers!
