For programming tools like Workspace
For simple examples - Terse Guide to Squeak at
For Morphic GUI - John Maloney's
Search past archives of beginner's list for other recommendations.

Open an existing image, bring up the world menu and do a "save as" under a new

The grey sheet is your "world". When you start Squeak for the first time, you
are shown a blank project. You add code (changeset) to the world by
programming using Workspace or Class Browser. Usually the first step is to give
a name to the project.
Project current renameTo: 'Parrot'
When a new project is created, the parent project carries a thumbnail picture
of the new project. If you jump back to the parent from the Projects menu, you
can see this thumbnail. Click on this to re-enter it or press middle button to
get a menu to remove ("expunge") just the thumbnail or thumbnail along with
its attached project object.
You can create many projects and carry them in Squeak image itself. or you can
export ("save" or "publish") it to a file or remote server and import ("load")
Watch out for beginner's trap - The parent only contains a reference to the
new project object but not the whole project object. Saving the parent does
not save the new project.
