The Suneido download includes the same documentation as the on-line manual. You can access it from the IDE windows via the Help menu or by pressing F1. If you want a standalone copy of the documentation use Edit a Book from the IDE menu, and choose “suneidoc”. From BookEdit use Export Single Html File or Export Multiple Html Files (on the File menu). You can then access these files using a browser such as Internet Explorer, Firefox, Chrome, Opera, or Safari.
