+# MeshCollectionGenerator
+
+## Overview
+
+The `MeshCollectionGenerator` creates a new mesh that is a collection of
+submeshes (provides in the `inputs` parameter`), The submeshes are not linked in
+any way and interaction between them only occurs due to contact or other
+constraints.

 ## Overview
 
-The `StitchedMeshGenerator` object allows for multiple mesh files to be "stitched" together to form a single mesh for use in a simulation.
+The `StitchedMeshGenerator` object allows for multiple mesh files to be
+"stitched" together to form a single mesh for use in a simulation. This
+generator will combine overlapping nodes and turn overlapping external sides
+into internal sides to form a connected mesh.
