+UHD Firmware and FPGA Images Builder
+===============================================================
+
+The images directory contains the following:
+* A Makefile for building firmware and FPGA images
+* A CMake file for building an images package
+
+This provides a clean and organized way to build all of the firmware and FPGA
+images, the source code for which is in the `firmware` and `fpga` directories
+one level above this.
+
+The Makefile and build systems for the images are *probably* Unix-specific.
+It's best to build the images on a Unix system with standard build tools.  The
+CMake package target will create an installable images package for your system.
+
+__To build the images (unix):__
+
+1. `make clean`
+2. `make images`
+
+__To build the package (unix):__
+
+1. `mkdir build`
+2. `cd build`
+3. `cmake -DCPACK_GENERATOR=<type> ../`
+4. `make package`
+
+The package generator types are described here:
+http://www.cmake.org/Wiki/CMake:CPackPackageGenerators
+
+__Fedora note:__
+
+The sdcc binaries are prefixed with "sdcc-" which breaks the build.
+However, /usr/libexec/sdcc contains properly named sdcc binaries.
+`export PATH=${PATH}:/usr/libexec/sdcc`
