+
+    .PARAMETER Version
+    The version of Go that should be built.
+
+    .PARAMETER Platform
+    The platform of Go that should be built.
+
+    .PARAMETER Architecture
+    The architecture with which Go should be built.
+
+    .PARAMETER TempFolderLocation
+    The location of temporary files that will be used during Go package generation. Using system BUILD_STAGINGDIRECTORY variable value.
+
+    .PARAMETER ArtifactLocation
+    The location of generated Go artifact. Using system environment BUILD_BINARIESDIRECTORY variable value.
