 		Creates a project/file from a template.
 
@@ -49,6 +49,10 @@
 		By default, all parameters will be replaced during invocation.
 		In Raw mode, this is skipped, reproducing mostly the original template input (dynamic scriptblocks will now be named scriptblocks)).
 
+	.PARAMETER GenerateObjects
+		By default, Invoke-PSMDTemplate generates files.
+		In GenerateObjects mode, no file but objects are created.
+
 	.PARAMETER Force
 		If the target path the template should be written to (filename or folder name within $OutPath), then overwrite it.
 		By default, this function will fail if an overwrite is required.
