+twinkl-client
+=============
+
+Compile
+-------
+```
+git clone git@github.com:LongHairedHacker/twinkl-client.git
+cd twinkl-client
+git submodule init
+git submodule update
+make
+```
+
+Usage
+-----
+```
+twinkle-client <twinkl server> <priority>
+```
+
+* **twinkle server**: The ip or hostname of the twinkl-server
+* **priority**: Priority of your packet 0 is highest 7 is lowest
+
+twinkl-client reads a list of channel value pairs from stdin.
+One pair per line in the format `<channel> : <value>`.
+Channels range from 0 to 511 while values range from 0 to 255.
+Both can be entered in decimal or hexadecimal (prefix with *0x*).
+An empty line sends the twinkl packet containing all values since the last empty line.
+An EOF (Ctrl-D) also sends the twinkel packet and terminates the client.
+
+Only channels that have been assigned a value before sending the packet will
+be reserved for usage by your priority level.
+This implies that if you want a channel to stay at 0 without a lower priority level
+being able to override it you have to set it to 0 in every packet you send.
+It is also a good Idea to send an empty packet (newline directly followed by a EOF) 
+before killing the client, as it will clear any leftover reserved channels
+for your priority level.
