+## 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
+    └── js/
+        ├── bootstrap.bundle.js
+        ├── bootstrap.bundle.js.map
+        ├── bootstrap.bundle.min.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/4.3/assets/js/src/search.js` file.
+
+### Running documentation locally
+
+1. Run through the [tooling setup](https://getbootstrap.com/docs/4.3/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/).
+

+## 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.
