## Documentation
Bootstrap's documentation, included in this repo in the root directory, is built with [Hugo](https://gohugo.io/) and publicly hosted on GitHub Pages at . 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 Hugo (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 Hugo by reading its [documentation](https://gohugo.io/documentation/).
