--- layout: default title: Installation description: Instructions on how to install the league/commonmark library --- # Installation The recommended installation method is via Composer. In your project root just run: ```bash composer require league/commonmark:^1.4 ``` Ensure that you’ve set up your project to [autoload Composer-installed packages](https://getcomposer.org/doc/01-basic-usage.md#autoloading). ## Versioning [SemVer](http://semver.org/) will be followed closely. **It's highly recommended that you use [Composer's caret operator](https://getcomposer.org/doc/articles/versions.md#caret-version-range-) to ensure compatibility**; for example: `^1.4`. This is equivalent to `>=1.4 <2.0`.
