# What is Yak?

This guide introduces the Yak package manager.

## Overview

Yak is a package manager for the Rhino ecosystem. Yak assists in the discovery, installation, and management of Rhino and Grasshopper resources. Examples include plug-ins, components, scripts, and material definitions.

Yak has several goals.

• Make it easier for users to discover and manage plug-ins and more
• Help developers to share their work
• Provide simple system administration tools

Not wanting to reinvent the wheel, we’ve taken inspiration from Linux and the software development world. The package management system can be broken down into three main areas.

## Server

The package server is the heart of the system. It can be hosted almost anywhere and keeps the packages organised for its clients – the command line tool and Rhino (via integrations).

## Command Line Tool

The command line tool provides a basic interface but with full functionality. It is modelled on well known domain-specific package managers such as Ruby’s gem and Python’s pip. It communicates with the server as well as hooking into Rhino Accounts for authentication.

## Integrations

Built on top of the same code that is used by the command line tool, integrations provide direct access to the package ecosystem from inside of Rhino.

Thus far Yak has been integrated into Grasshopper’s “Unrecognized Objects” dialog, providing package restore functionality.
