 `dim` - the dimension they are to be stacked along, can be either `x`, `y`, or `z`. If the argument `none` is passed then the cells are just overlaid. Future options will include a delete overlap command.
 
+**Additional options:**
+
+**Shift**
+
+```
+shift x y z
+```
+
+If the shift command is passed to mode merge then each file after the first file in the merge command is displaced by the vector `[x, y, z]`. This is additive so if you are merging three files and this command is passed then the second file is shifted by `[x,y,z]` and the third file is shifted by `2*[x,y,z]`. 
+
+Example: `cacmb --merge z 2 Cu.mb Cu2.mb Cu3.mb Cumerged.mb shift 2 0 0` will shift the atomic and element positions in the `Cu2.mb` file by `[2,0,0]` and the positions in `Cu3.mb` by `[4,0,0]`.
+
+**Wrap**
+
+```
+wrap
+```
+
+This will wrap atomic positions back inside the box. Effectively as if periodic boundary conditions are applied so that atoms which exit from one side of the simulation cell enter back in through the other.

 ## Options
 
 Options are additional portions of code which have additional functionality. Options are performed in the order that they appear in the argument list and can be added to any mode. If wanting to use strictly options use `--convert` to specify input and output files.
