+### Using GitHub Codespaces for development
+
+To get started, create a codespace for this repository by clicking this 👇 
+
+[![Open in GitHub Codespaces](https://github.com/codespaces/badge.svg)](https://codespaces.new/withastro/astro)
+
+Your new codespace will open in a web-based version of Visual Studio Code. All development dependcies will be preinstalled and the tests will run automatically ensuring you've got a green base from which to start working.
+
+**Note**: Dev containers is now an open spec which is supported by [GitHub Codespaces](https://github.com/codespaces) and [other supporting tools](https://containers.dev/supporting).
