Its just an empty repo to use codespaces when I dont need to create separate repo for project.
"Spin up fully configured dev environments in the cloud that start in seconds with up to 60 hours a month free." Github Codespaces https://github.com/features/codespaces
To begin using codespaces you got to have a repository with minimum one file, readme for example. Or create codespaces for any of your current project repos.
Happy coding!
