 Yes! MinVer is also available as a [command line tool](https://www.nuget.org/packages/minver-cli). Run `minver --help` for usage. The calculated version is printed to standard output (stdout).
 
+Sometimes you may want to version both .NET projects and other outputs, such as non-.NET projects, or a container image, in the same build. In those scenarios, you should use both the command line tool _and_ the regular MinVer package. Before building any .NET projects, your build script should run the command line tool and set the [`MINVERVERSIONOVERRIDE`](#options) environment variable to the calculated version. The MinVer package will then use that value rather than calculating the version a second time. This ensures that the command line tool and the MinVer package produce the same version.

 ### What if the history diverges, and more than one tag is found?
 
 The tag with the higher version is used.
