 When backing up files opened with exclusive lock in Windows, Kopia would fail the snapshot task because it can't read the file content.
 One of the popular solutions is taking a [shadow copy](https://en.wikipedia.org/wiki/Shadow_Copy) of the storage volume and ask Kopia to backup that instead.
 
-In this example, we will use PowerShell to take a shadow copy in the "before" action of the target directory and clean everything up in the "after" action.
+In this example, we will use [PowerShell](https://github.com/PowerShell/PowerShell/) to take a shadow copy in the "before" action of the target directory and clean everything up in the "after" action.
+The script also self-elevates as administrator (required to take shadow copy) if Kopia is ran with an unprivileged account.
+
+Make sure `pwsh` is reachable in the PATH environment variable.
