 ## Introduction
 
-The tool `AddTopLayer` adds one layer of elements with a specified thickness `thickness` on top of an existing mesh `input-mesh` and returns the newly generated mesh `output-mesh` that has an new top layer.
+The tool `AddLayer` adds one layer of elements with a specified thickness
+`thickness` on either on top or bottom of an existing mesh `input-mesh` and
+returns the newly generated mesh `output-mesh` that has an new layer.
 
-One might want to take care that the material groups are reduced, eg. material groups should not be [0,2,5], but [0,1,2]. The new layer will have the material group number of the highest material group +1.
+One might want to take care that the material groups are reduced, eg. material
+groups should not be [0,2,5], but [0,1,2]. The new layer will have the material
+group number of the highest material group +1. With the switch
+`--copy-material-ids` the MaterialIDs of the extruded layer will be kept.
 
 The tool requires the [OGS-6 node ordering](http://doxygen.opengeosys.org/index.html) in the elements. A different node ordering may lead to unexpected results. In case one might try to change the ordering using the tool `NodeReordering`.
 
 ## Usage
 
 ```bash
-AddTopLayer -i <input-mesh> -o <output-mesh> [-t <thickness>]
+AddLayer -i <input-mesh> -o <output-mesh> [-t <thickness>]
 ```
