 # pixelvloed
 PixelVloed udp / binary transport PixelFlut version
+
+You will find a bunch of files in this project, most noteworthy, A client, and 
+a server for the pixelvloed protocol.
+
+The server can be run on most machines and uses pygame or SDL to display the 
+received pixels on the screen.
+
+To start a server on a linux machine start:
+  vloed.py
+
+To start a server on a machine which has trouble getting Pygame to intall, eg a 
+Mac OSX computer, start:
+  sdlvloed.py
+  
+Both have a series of options:
+  Options:
+  -h, --help    show this help message and exit
+  -v (displays the version)
+  -i IP (The UDP listen ip address)
+  -p PORT (The UDP listen port)
+  -x WIDTH (The width of the display)
+  -y HEIGHT (The height of the display)
+  -m MAXPIXELS (the max amount of pixels people can send in one packet)
+  -f FACTOR (an optional pixel zoom factor, received pixels will be zoomed by this factor)
+  
+If you want to run a pixelvloed server on a raspberry PI (zero) you can start:
+  vloed
+
+Which can be compiled doing:
+  gcc vloed.c -o vloed
+  
+  
+On the client side:
+
+You can use the python version which can be started with:
+  client.py
+  
+You can also use the javascript/node version:
+  client.js
+  
+These by default try to find a pixelvloed server and start sending random pixels
+Both clients also present options to set a static IP.
+
+It is left as en exercise to the reader to code new fancy effects that target 
+one or more screens.
