A package is a container that stores various types of features or assets, such as:
- Editor tools and libraries, such as a text editor, an animation viewer, or test frameworks.
- Runtime tools and libraries, such as the Physics API or a Graphics pipeline.
- Asset collections, such as Textures or animations.
- Project templates to share common project types with others.
Packages deliver a wide range of enhancements to Unity through the Package Manager. To help find and use these packages, the Package Manager window provides collections of packages that you can use together, called feature sets.
In the Editor, you can access the Package Manager window through this menu: Window > Package Manager.
The Package Manager also supports management of packages you download or import from the Unity Asset Store.
Unity provides three Package Manager interfaces: Package Manager window, scripting API, and manifest files. The following table contains introductions to each interface, and more.
