     These Tasks are Git tasks to work with repositories used by other tasks
     in your Pipeline.
+
+    The git-clone-checkout Task will clone a repo from the provided url into the
+    output Workspace. By default the repo will be cloned into the root of
+    your Workspace. You can clone into a subdirectory by setting this Task's
+    subdirectory param. This Task also supports sparse checkouts. To perform
+    a sparse checkout, pass a list of comma separated directory patterns to
+    this Task's sparseCheckoutDirectories param.
