How rnr Works

rnr binaries are committed to your repository. Contributors clone and run - no installation needed.

curl -fsSL .../rnr-linux-amd64 -o rnr
# Initialize (downloads platform binaries)
./rnr init
# Commit everything
git add .rnr/ rnr rnr.cmd rnr.yaml

For Contributors

# Clone the repo
git clone <repo>
# Run any task - it just works!
./rnr build
# Works on any platform
rnr test # Windows
