Use the Unity Package Manager (in Unity’s top menu: Window > Package Manager) to view which packages are available for installation or already installed in your project. In addition, you can use this window to see which versions are available, and install, remove, disable, or update packages for each project.
The Package Manager window displays:
(A) The experimental package indicator, which warns you if your project contains experimental packages.
(B) The add button, which you can click to install a package directly into your project by entering a git URL, a local path, or a package name.
(C) The Packages drop-down menu, which you can use to change what appears in the list (context).
(D) The Sort drop-down menu, which lets you sort the list of packages by name or date.
For Asset Store packages, two additional controls give you some additional filtering options:
(E) Advanced settings , which you can use to access the project settings for the Package Manager or reset your project’s packages to default.
(F) The search box, which you can use to look for packages by name.
(G) The packages list view, which displays all packages that match the filter and search parameters you specify.
(H) The package-specific detail view, which displays information specific to the package selected in the list.
(I) The status bar, which displays messages about the package load status and any errors or warnings.
(J) The reload drop-down menu, which lets you force Package Manager to reload or resolve the packages in your project.
(K) Buttons to perform any of the following actions:
The advanced settings drop-down menu allows you to perform these actions:
|Drop-down menu item||Action results|
|Advanced Project Settings||Select this item to open the Package Manager project settings, where you can:

- See which packages are installed as dependencies of another installed package (indirect dependencies).
|Reset Packages to defaults||Select this item to return to Package Manager default settings.
Warning: This removes all customization from your project manifest file. Only use this a last resort when you can’t figure out what is wrong with your project manifest file.
The Package Manager displays messages in the status bar at the bottom left of the Package Manager window.
There are typically four status messages that you might see:
The first time you open the Package Manager window in a new project, the Loading packages message appears briefly:
This message also appears when you select Refresh list from the reload drop-down menu.
Most of the time the status bar displays the date and time of when the Package Manager window last refreshed its information:
However, if the Package Manager detects a problem, such as a missing network connection, the Package Manager displays an error in the status bar:
If your network connection is working, but you are not signed into your Unity account, the Package Manager doesn’t display any Asset Store packages. When you try to use the My Assets scope, the Package Manager displays an error in the status bar:
In the list view, click the Sign in button to sign into your Unity account through the Unity Hub.
