Documentation

Bootstrap's documentation, included in this repo in the root directory, is built with Hugo and publicly hosted on GitHub Pages at https://v5.getbootstrap.com/. The docs may also be run locally.

Documentation search is powered by Algolia's DocSearch. Working on our search? Be sure to set

debug: true

in

site/assets/js/src/search.js

file.

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.

Versioning

For transparency into our release cycle and in striving to maintain backward compatibility, Bootstrap is maintained under the Semantic Versioning guidelines. Sometimes we screw up, but we adhere to those rules whenever possible.
