## 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.

## 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 . 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 the `_scripts.html` include.
### Running documentation locally
1. Run through the [tooling setup](https://github.com/twbs/bootstrap/blob/v4-dev/docs/getting-started/build-tools.md#tooling-setup) to install Jekyll (the site builder) and other Ruby dependencies with `bundle install`.
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 `bundle exec jekyll serve` in the command line.
4. Open in your browser, and voilà.
Learn more about using Jekyll by reading its [documentation](https://jekyllrb.com/docs/home/).
### Documentation for previous releases
Documentation for v2.3.2 has been made available for the time being at while folks transition to Bootstrap 3.
[Previous releases](https://github.com/twbs/bootstrap/releases) and their documentation are also available for download.
