+**Acknowledgement**  The development of this software is part of the scientific program of the EU MaX Centre of Excellence for Supercomputing Applications (Grant No. 676598) and has been partly funded through it.
 
-The file analysis.py is the main program, that can run from the command line with python 2.7.
-It executes all the parts of cepstral analysis producing the final result and a number of figures in a pdf output.
+### Usage
+The code can be used as a **library**, for example in a Jupyter notebook. 
+In the "example" folder you can find some examples. 
+
+Alternatively, you can run the code "analysis.py" from the **command line**.
+It can execute most of the cepstral analysis routines, writing the result in a series of data files and PDF plots.
 See help (python analysis.py --help) for more informations.
 
-The code can be used as a library, in a jupyter notebook for example, as shown in the example directory.
+### Requirements
+ - Python 2.7
+ - Numpy
+ - Scipy
+ - Matplotlib
