 These simple scripts here are intended to help you understand the basics of the generated data from Cholla.
 
 ## Merging HDF5 files
-Multi-processor runs generate HDF5 files per-timestep per-processor.
-To treat each timestep together we want to merge those per-processor HDF5 files.
 
-| Script | Concatenate |
-| ------ | ----------- |
-`cat_dset_3d.py`    | 3D HDF5 datasets
-`cat_projection.py` | The on-axis projection data created when the -DPROJECTION flag is turned on
-`cat_rotated_projection.py` | The rotated projection data created when the -DROTATED_PROJECTION flag is turned on
-`cat_slice.py` | The on-axis slice data created when the -DSLICES flag is turned on
+Multi-processor runs generate HDF5 files per-timestep per-processor. Merging these per process output into a single file can be done with the concatenation scripts detailed in the "Outputs" section of the wiki.
 
 ## Plotting data
 We here present simple Python matplotlib-based scripts to plot density, velocity, energy, and pressure.
