DevSession Common Package
TLDR: You're probably looking for the readme of the main repo.
This package contains utilities for the collaborative webbased IDE devsession. The package is organized as part of a monorepo located at https://github.com/lukasbach/devsession. Follow the instructions there to setup and run the application for development purposes.
If you just want to run the devsession application, run npx devsession in the directory in which
you want to host the coding session or download prebuilt binaries from here.
