 # NQR Bloch Simulator for Python
 
-This is a Python implementation of an NQR Bloch Simulator.
+This is a Python implementation of an NQR Bloch Simulator. It can be used for simulating NQR spectroscopy signals in the time domain. The simulator is based on the paper [1].
 
 Right now the implementation is in a early stage and has not yet been tested and verified.
