This is the documentation for the unsupported version 2.1. Please consider upgrading your code to the latest stable version
Installation
The recommended installation method is via Composer.
composer require "league/commonmark:^2.1"
Ensure that you’ve set up your project to autoload Composer-installed packages.
Versioning
SemVer will be followed closely. It’s highly recommended that you use Composer’s caret operator to ensure compatibility; for example: ^2.1. This is equivalent to >=2.1 <3.0.
