Please first read the [issue guidelines](https://github.com/twbs/bootstrap/blob/v4-dev/.github/CONTRIBUTING.md#using-the-issue-tracker) and search for existing and closed issues.

## 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.
