What you need for this book

To create projects using the Scratch 2 project editor, you need a relatively recent web browser (Chrome 7 or later, Firefox 4 or later, or Internet Explorer 7 or later) with Adobe Flash Player Version 10.2 or later installed. Scratch 2 is designed to support a screen resolution of 1024 x 768 or larger. If your computer doesn't meet these requirements, you can try downloading and installing Scratch 1.4, which you can still use to share projects to the Scratch 2 website.

An offline Scratch 2 editor is also available. You can also still use Scratch 1.4. Note that you can have both Scratch 1.4 and 2 on your computer.

The software to download are as follows:

• The Scratch 2 offline editor can be downloaded from the following link: http://scratch.mit.edu/scratch2download
• The Scratch 1.4 editor can be downloaded from the following link: http://scratch.mit.edu/scratch_1.4
