This page won't help you learn deep secrets of Squeak. What it will do is provide handy solutions for common problems. This page is just as editable as any other on the Wiki, so feel free to update a recipe or add a new one. If you think something is missing, feel free to add a question without an answer – someone will hopefully come along who can fill in the details.
Please read Squeak Cookbook Style before making significant changes, to see what others were thinking. Of course, feel free to improve on it.
