-This directory contains programs based on gr-gsm. Currently two are available:
-- airprobe_rtlsdr.py
-- airprobe_file.py
+This directory contains programs based on gr-gsm:
+* grgsm_decode     (old name: airprobe_decode.py) - program for decoding C0 channel 
+                    which is most close in terms of functionality to the old gsm-receiver 
+                    from Airprobe project, with ability to decode signalling channels and traffic channels with speech 
+                    (analysis of the data can be performed in Wireshark, decoded sound is stored to an audio file),
+* grgsm_livemon    (old name: airprobe_rtlsdr.py) - interactive monitor of a single C0 channel with analysis 
+`                   performed by Wireshark (command to run wireshark: sudo wireshark -k -f udp -Y gsmtap -i lo),
+* grgsm_scanner    (old name: airprobe_rtlsdr_scanner.py) - an application that scans GSM bands and prints 
+                    information about base transceiver stations transmitting in the area.
 
-- airprobe_usrp can be used but it will need to be customized in the gnuradio-companion for given configuration (for example address of the USRP will need to be changed).
+There are following helper programs for grgsm_decode program:
+
+* grgsm_capture    (old name: airprobe_rtlsdr_capture.py) - program for capturing GSM signal to a file 
+                    that can be later processed by grgsm_decode,
+* grgsm_channelize (old name: gsm_channelize.py) - splits wideband capture file into multiple files - each contain 
+                  single GSM channel.
