The easiest way to learn the library is to try it out. There’s no substitute for experimentation in a live image!
The code snippets in these pages cannot be as interactive as the real thing. It can be difficult to get a feel for the system without hands-on experience. Install the system to try it out.
If you prefer to load the completed tutorial classes, rather than
building them yourself while following along with each tutorial, you
can load the
ActorExamples package from SqueakSource:

Examples and demos
Besides the tutorial examples below, the library includes a handful of
demos and larger examples in the
The Counter tutorial goes over the basics, with a simple stateful actor.
