Editing files in your GitHub repo online with Codespaces

Articles online about how to enable your GitHub projects to use Codespaces are not particularly clear about how to get started, whether you need access to the beta or not, whether it is free for personal use or whether you need to pay for a subscription.

I suspect there’s been some changes since the service launched. The easiest way to open a Codespace to edit any file in your repo is to browse to a file and drop down the edit menu and then select Open in GitHub.dev

One you open a single file, the VS Code web interface will load, allowing you to edit any file in that project.
