Building This Manual
This FPGA manual is available on the web at http://files.ettus.com/manual/md_fpga.html for the most recent stable version of UHD. If you wish to read documentation for a custom/unstable branch you will need to build it and open it locally using a web browser. To do so please install Doxygen on your system and run the following commands:
$ cd docs
$ make
$ sensible-browser html/index.html
