We’ve moved the Meta Environment from github.com/iandunn/wordpress-meta-environment to github.com/wordpress/meta-environment. Links to the old repository will redirect to the new one.
The goal of the Environment is to make it easy to contribute to the Meta team by giving you a local development environment that’s already setup with the official websites, so you don’t have to manually piece them together.
If you’ve been wanting to working on a patch for something, please check it out 🙂
