Workshop with Heiko Behrens and Moritz Eysholdt at EclipseCon 2010, Santa Clara, CA.

1. Setting Up the
Development Workbench
• Copy both to your local disk:
• the right archive for your platform
• the folder material
• Hand the USB stick to the attendee next to you.
• Unzip the archive and start the included Eclipse with a
fresh workspace.
• NOTE: On Windows systems, make sure you pick a short
directory name and everything gets extracted without
errors.

2. meets
Developing an editor
for the e4 workbench model
