Your OS will need to have the driver for the FTDI USB Serial converter. 
Ubuntu has this in the default install.  

Connect the LED OCD to the host machine using a USB cable, then look for the 
tty device to be created.

  dmesg | grep ttyUSB

Both the web server user and any user that wants to use the CLI app will need 
to be part of the dialout group so that they can 'talk' to the tty device.  For 
now, we'll only add our default user, and we'll add the web server after we 
install it. 

  sudo usermod -a -G dialout ledocd

You might need to install gcc to be able to compile stuff.

  sudo apt-get install gcc
  sudo apt-get install make

Compile and install the command line application

  cd ledocd_cli
  make
  sudo cp ledocd_cli /usr/bin/
  ledocd_cli -h

You should see usage information.  If not, something went wrong.

Install the web server.  If you're using Ubuntu, you can easily install Apache.

  sudo apt-get install apache2
  sudo usermod -a -G dialout www-data

You can test the server installation by using a web browser and going to:

  http://[IP OF SERVER]/index.html

You'll probably need to enable CGI.

  sudo ln -s ../mods-available/cgi.load /etc/apache2/mods-enabled/cgi.load
  sudo service apache2 restart

Copy the LED OCD files into their locations.  Some of the destinations will 
depend on your choice of OS.  Google is your friend.

  sudo cp ledocd_gui/gui/cgi/* /usr/lib/cgi-bin/
  sudo cp -r ledocd_gui/gui/script/www/* /var/www/html/
  sudo cp -r ledocd_gui/ /usr/share/ 

You might need to make the CGI files executable.

  sudo chmod +x /usr/lib/cgi-bin/*

If all went well, you should now be able to browse to the LED OCD Configuration
address:

  http://[IP OF SERVER]/cgi-bin/ledocd.html

Good luck.  I am happy to answer a few questions, but please try to keep them 
to a minimum.  For now, this is meant as more of a DIY project.
