 ## HDF5 Input ##
 
-The option to use HDF5 input instead of serial ASCII input is now
-available in branch `master` and Branches `mpi-sm-hdf5`. The
-Python-script `convert_to_hdf5.py` converts parts of the standard
-ASCII input file into and hdf5-file called `<input>_conv.h5`. Parts
-which are not converted to hdf5-arrays are stored in a new ASCII-file
-called `<input>_conv`. Due to changes in the SHEMAT-Suite reading
-routines, most of the input data is then read from the HDF5-file which
-is considerably faster than reading from the ASCII-file and has
-advantages of parallel I/O.
+# Input File Conversion to HDF5-format
 
-How to use it:
+The user input for SHEMAT-Suite is provided in an ASCII-file. For reducing the
+reading time of larger input files, SHEMAT-Suite provides the option to read 
+HDF5 input instead. Theresore, we provide a Python-script for converting the 
+ASCII input file, which is created by the user, into an HDF5 input file.
 
-1.) Copy the python code `convert_to_hdf5.py` from the code directory
-to your model directory.
+The script `convert_to_hdf5.py` converts parts of the standard ASCII input file
+into and HDF5-file called `<input>_conv.h5`. Those parts which are not converted
+to hdf5-arrays are stored in a new ASCII-file called `<input>_conv`. 
+Most of the input data, especially large arrays, is then read from the 
+HDF5-file, which is considerably faster than reading from the ASCII-file.
 
-2.) For using the converter, the Python module has to be loaded.
+**How to use it:**
 
-3.) Conversion of standard SHEMAT-Suite input file:
+0.) Prerequisite: Python
+
+1.) Download the python scipt `convert_to_hdf5.py` 
+from https://git.rwth-aachen.de/SHEMAT-Suite/shemat-suite_scripts-open
+
+2.) Conversion of standard SHEMAT-Suite input file:
 `./convert_to_hdf5.py <inputfile>`
 
-4.) The file shemade.job has to contain the name of the newly
-generated ASCII-file `<inputfile>_conv`
+3.) Write the name of the newly generated ASCII-file `<inputfile>_conv` 
+into the file `shemade.job `.
+
+4.) Execute SHEMAT-Suite.
 
-5.) Execute SHEMAT-Suite.
 
+**Important note:** 
 
-Important note: The input of multiple values for e.g. boundary
-conditions either has to be written in one line or the number of
-entries has to be defined by using the keyword records. Otherwise the
-converter will give an error!

-Please test the HDF5 input option with your models and report any
-difficulties like the one noted above, so that they can be adapted in
-the future.
