To find the documentation for the latest Bootstrap 3 compatible release, [go here](https://react-bootstrap-v3.netlify.com). ### Migrating from Bootstrap 3 to Bootstrap 4 If you would like to update React-Bootstrap within an existing project to use Bootstrap 4, please read our docs for **[migrating to React-Bootstrap V1](https://react-bootstrap.github.io/migrating/)**. ## Related modules - [react-router-bootstrap][react-router-bootstrap] – Integration with [React Router][react-router] - [Awesome React Bootstrap Components][awesome-react-bootstrap-components] - Additional components like off-canvas navbar, switch and sliders. ## Local setup Yarn is our package manager of choice here. Check out setup instructions [here](https://yarnpkg.com/en/docs/install) if you don't have it installed already. After that you can run `yarn run bootstrap` to install all the needed dependencies. From there you can: - Run the tests once with `yarn test` (Or run them in watch mode with `yarn run tdd`). - Start a local copy of the docs site with `yarn start` - Or build a local copy of the library with `yarn run build` ## CodeSandbox Examples [Click here](https://github.com/react-bootstrap/code-sandbox-examples) to explore some React-Bootstrap [CodeSandbox](https://codesandbox.io/) examples.
