+Building UHD Applications using CMake
+=====================================
+
+This directory contains a tiny example of a UHD-based application.
+Unlike the other examples, it is completely independent of the UHD
+source tree and can be compiled from any path as long as UHD is
+currently installed on the current machine.
+
+To try it out, run these commands:
+$ mkdir build/ # Creates a new build directory
+$ cd build/
+$ cmake ..
+$ make
+
+This will find the UHD libraries, and link and compile the example
+program. Include header directories and library names are automatically
+gathered.
+
+See the CMakeLists.txt file to figure out how to set up a build system.
