+== Requirements ==
+The AmbientTalk/2 interpreter is written in pure Java and requires a regular J2SE Java Virtual Machine supporting version 1.3 or higher.
 == Installation and Usage ==
-To run the interactive shell, it suffices to launch the included **iat** shell script. IAT is a simple read-eval-print loop: statements are typed at the command line, evaluated and the result is printed to standard output. Note that the log and error traces are piped to the console.

-<note>We advise you to add **iat** to the **$PATH** environment variable, such that **iat** can be invoked from any directory. </note>
+The system library shipped with the build can be found in the ''at/'' directory. It includes, among others, some demo applications and additional language constructs (most notably future-type asynchronous message sends). Also, the file ''at/init/init.at'' is loaded by default in each actor created at runtime to intialize that actor's global scope.

 For a full overview of the supported features, open the Bundles > Bundle Editor > Show Bundle Editor menu and select the AmbientTalk 2 bundle in the bundle editor. All available actions, together with their hotkey are listed there.
+== Versions ==
+Currently, AmbientTalk/2 requires a J2SE JVM to run. We are planning to port AT/2 to J2ME (CDC) as soon as possible. This would allow AT/2 to run on PDAs and high-end cellular phones. A port to J2ME CLDC is currently not planned.
 == Documentation ==
+A tutorial describing AmbientTalk/2 will be available shortly.
 The [[http://prog.vub.ac.be/amop/at2doc|Javadoc of the Interpreter]] is also online. It provides documentation about the implementation of the interpreter. A design document describing the design of the interpreter will follow soon.
