 Identifying USRPs
 ------------------------------------------------------------------------
-Every device has several ways of identifying it on the host system:
+Devices are addressed through key/value string pairs.
+These string pairs can be used to narrow down the search for a specific device or group of devices.
+Most UHD utility applications and examples have a --args parameter that takes a device address;
+where the device address is expressed as a delimited string.
+See the documentation in types/device_addr.hpp for reference.
 
-* **Serial:** A globally unique identifier.
-* **Address:** A unique identifier on a network.
-* **Name:** An optional user-set identifier.

 Device discovery via command line
 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-A "find devices" utility application comes bundled with the UHD.
-The find devices application will search for all devices on the host system and print the results.
+Devices attached to your system can be discovered using the "uhd_find_devices" program.
+The find devices program scans your system for supported devices and prints
+out an enumerated list of discovered devices and their addresses.
+The list of discovered devices can be narrowed down by specifying device address args.

+Properties of devices attached to your system can be probed with the "uhd_usrp_probe" program.
+The usrp probe program constructs an instance of the device and prints out its properties;
