# Welcome

`nr` (short for "[npm run](https://docs.npmjs.com/cli/v7/commands/npm-run-script)") is a modern, type-safe task runner for JavaScript projects.

It can serve as a replacement for or complement to [NPM package scripts](https://docs.npmjs.com/cli/v7/commands/npm-run-script).

This guide will show you how to use `nr` to define, organize and document package scripts.
