--- layout: default title: Installation description: Instructions on how to install the league/commonmark library --- # Installation The recommended installation method is via Composer. ```bash composer require "league/commonmark:^2.2" ``` 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: `^2.2`. This is equivalent to `>=2.2 <3.0`.
