-## Websocket Server for Arduino
+## Arduino Websocket Server for Door Controller Test Tool
 
-This library implements a Websocket server running on an Arduino. It's based on the [proposed standard][1] published December 2011 which is supported in the current versions (June 2012) of Firefox, Chrome, and Safari 6.0 beta (not older Safari, unfortunately) and thus is quite usable.

+The library is used by the Door Controller Test Tool.

+### Limitations
 
 The implementation in this library has restrictions as the Arduino platform resources are very limited:
 
 * The server **only** handles TXT frames.
 * The server **only** handles **single byte** chars. The Arduino just can't handle UTF-8 to it's full.
-* The server **only** accepts **final** frames with maximum payload length of 64 bytes. No fragmented data, in other words.
-* For now, the server silently ignores all frames except TXT and CLOSE.
-* The server **only** handles one client at a time. Trying to connect two at the same time will force the old client to disconnect.
-* There's no keep-alive logic implemented.
+* The server **only** accepts **final** frames with maximum payload length of 256 bytes. No fragmented data, in other words.
+* For now, the server silently ignores all frames except TXT, CLOSE and PONG.

-### Getting started
-
-Install the library to "libraries" folder in your Arduino sketchbook folder. For example, on a mac that's `~/Documents/Arduino/libraries`.
-
-Try the supplied echo example together with the the [web based test client][2] to ensure that things work.
-
-Start playing with your own code and enjoy!

-### Feedback
-
-I'm a pretty lousy programmer, at least when it comes to Arduino, and it's been 15 years since I last touched C++, so do file issues for every opportunity for improvement.
-
-Oh by the way, quoting myself:
-
-> Don't forget to place a big ***fat*** disclaimer in the README. There is most certainly bugs in the code and I may well have misunderstood some things in the specification which I have only skimmed through and not slept with. So _please_ do not use this code in appliancies where living things could get hurt, like space shuttles, dog tread mills and Large Hadron Colliders.
