+that should be copied (manually or by using the convenience script) and modified,
+if needed, to meet the system configuration.
 On many systems they should work out of the box.
 
+By default, all applications will search for config files in the user's home
+directory (~/.srs) upon startup.
+
 Note that you have to execute the applications with root privileges to enable
 real-time thread priorities and to permit creation of virtual network interfaces.
 
-Also note that when you run the applications that all additional configuration files,
-for example the UE database file needed by srsEPC, reside in your current working directory.
-If that is not the case, you may need to specify the location of those files as
-command line arguments, for example using the --hss.db_file parameter in srsEPC.

 srsENB and srsEPC can run on the same machine as a network-in-the-box configuration.
 srsUE needs to run on a separate machine.

-config example and UE database file.

+will be assigned an IP in this network.
