+.DESCRIPTION
+    Compute AssemblyVersion and PackageVersion
+
+.PARAMETER branchName
+    The branch of the trigger repo for which the build has been queued.
+    Please, use $(Build.SourceBranchName)
+
+.PARAMETER buildNumber
+    The name of the completed build, also known as the run number.
+    This value is formatted like "[Major].[Minor].[Revision].[Year:00].[DayOfYear].[BuildRevision]" (e.g. "4.6.1.24123.3")
+    Please, use $(Build.BuildNumber)
+
+.PARAMETER packageSuffix
+    Suffix to add to the computed version. Example "Preview", "RC.1", ...
+    This suffix overrides the one calculated for dev our main branches.
+    Default is "".
+
+.PARAMETER testProjects
+    Projects to tests, to define the variable "ShouldTest".
+    Not empty, ShouldTest will be "true".
+
+.EXAMPLE
+    $> .\compute-version-variables -branchName "dev" -buildNumber "4.6.1.24123.3" -packageSuffix "Preview"
