The Unity Manual provides documentation for a specific version of Unity. Each package has its own version, so each package provides documentation for a specific version of that package. For this reason, the package documentation isn’t part of the main Unity Manual documentation; instead, documentation for each package lives on its own micro-site on Unity’s documentation server.
To access the documentation for a specific package, you have two options:
When the package page opens, you can see four links at the top of the page.
To switch back and forth between the Manual documentation, the Scripting API documentation, the Changelog, and the License information for this package, click the corresponding link at the top of the page.
Each version of the Unity Manual documentation provides the Packages documentation page, which lists the packages you can use with that version of Unity:
You can click the link in the list to open the latest version of that package documentation, where latest means the highest version generated. If you can’t find the package you want in this list, there might be several reasons:
You might be able to access the documentation through the Packages window for preview packages and packages released in another version of Unity. In the case of private packages, try to contact the developer directly to request access.
You can find out more about a package by viewing its documentation, changelog, or license information.
To access any of these pages, you can click the View documentation, View changelog, or View licenses links from inside the Packages window.
To access the documentation for a specific package version:
Open the Packages window in Unity.
If you are looking for a preview package, select Show preview packages from the Advanced drop-down menu.
Select the package you want information for from the list on the left.
Expand the arrow to the left of the package in the list.
A new row appears, displaying the See all versions link.
Click the See all versions link.
A scrollable list appears with all available versions.
Click on another version to select it.
The package details appear in the pane on the right.
Notice the verified tag no longer appears in this example because version 1.2.4 of the TextMesh Pro package is not verified for Unity version 2019.1.
Click the View documentation link to open the documentation for the selected version of the package.
NOTE: If you are offline when you click the View documentation link and the package is on your computer (that is, embedded or installed from a local folder), the Package Manager opens the first MD file it finds under the
<package-root-folder>/Documentation~ folder in your default MD viewer. If the Package Manager installed the package from a server (that is, from a package registry server or a Git remote repository), the following message appears instead:
You can follow this procedure for any version of any package. Note that the documentation is not necessarily different for each package version release, since some version updates (patches) involve only bug fixes or trivial changes.
