 About OpenBSC
 =============
 
-OpenBSC is a minimalistic implementation of the GSM Network, with particular
-emphasis on the functionality typically provided by the BSC, MSC, HLR, VLR.

-Its only current interface is a mISDN based E1 interface utilizing the A-bis
-protocol between BSC and BTS.  In other words, you can connect an existing
-GSM Base Transceiver Station (BTS) through E1 to OpenBSC.
+Its currently supported interfaces towards the BTS are:
 
-So far, it has only been tested with the Siemens microBTS BS-11.  Test reports
-with other BTS are appreciated!

 This project is still in its early days, and there are lots of areas where it
 doesn't behave as per GSM spec.

+libosmocore
+===========
+
+Please note that as of March 2010, OpenBSC has a dependency to a library
+called "libosmocore".  You can obtain that library from
