 The Contiki Operating System
 
-Contiki is an open source, highly portable, multi-tasking operating
-system for memory-constrained networked embedded systems written by
-Adam Dunkels at the Networked Embedded Systems group at the Swedish
-Institute of Computer Science.
+Contiki is an open source operating system that runs on tiny low-power
+microcontrollers and makes it possible to develop applications that
+make efficient use of the hardware while providing standardized
+low-power wireless communication for a range of hardware platforms.
 
-Contiki is designed for embedded systems with small amounts of
-memory. A typical Contiki configuration is 2 kilobytes of RAM and 40
-kilobytes of ROM. Contiki consists of an event-driven kernel on top of
-which application programs are dynamically loaded and unloaded at
-runtime. Contiki processes use light-weight protothreads that provide
-a linear, thread-like programming style on top of the event-driven
-kernel. Contiki also supports per-process optional preemptive
-multi-threading, interprocess communication using message passing
-through events, as well as an optional GUI subsystem with either
-direct graphic support for locally connected terminals or networked
-virtual display with VNC or over Telnet.
+Contiki is used in numerous commercial and non-commercial systems,
+such as city sound monitoring, street lights, networked electrical
+power meters, industrial monitoring, radiation monitoring,
+construction site monitoring, alarm systems, remote house monitoring,
+and so on.
 
-Contiki contains two communication stacks: uIP and Rime. uIP is a
-small RFC-compliant TCP/IP stack that makes it possible for Contiki to
-communicate over the Internet. Rime is a lightweight communication
-stack designed for low-power radios. Rime provides a wide range of
-communication primitives, from best-effort local area broadcast, to
-reliable multi-hop bulk data flooding.
+For more information, see the Contiki website:
 
-Contiki runs on a variety of platform ranging from embedded
-microcontrollers such as the MSP430 and the AVR to old
-homecomputers. Code footprint is on the order of kilobytes and memory
-usage can be configured to be as low as tens of bytes.
-
-Contiki is written in the C programming language and is freely
-available as open source under a BSD-style license. More information
-about Contiki can be found at the Contiki home page:
