You should find all the documentation installed along with the RE installation under "C:\<YourInstallDir>\LiveCycle\ReaderExtensions\docs\EN".<br /><br />I think your best starting document would be "developer_guide.pdf" which provides sample code and everything you need to get started programming against the APIs.<br /><br />If you are just looking to start with a technology overview, go to
www.adobe.com, products, LiveCycle, and then Reader Extensions. There are plenty of white papers and data sheets to get you up to speed.<br /><br />Can you tell us what you are going to be doing specifically with RE?
