• Installs monorepo-builder which has valuable tools to manage monorepo e.g. validating dependencies are similar across packages
• Streamlines package dependencies
• Adds build workflows & dependabot configuration
• Updates README to reflect changes

I assume you can JIT into the repo and add the token.
