Very nice introduction to Xtext. It would be very helpful showing how to install Xtext as well. Thanks Paul.

@selcuk263 Thank you. It is a good point because installing xtext was originally a little complicated, but the last few times it has worked from the update site.

hey, I downloaded the whole eclipse that includes Xtext and it worked fine for me

@AgileJStructureViews Yes, I've tried installing Xtext from Indigo update site. And now it works perfectly. The only issue was running MWE2 workflow which requires downloading Antlr3. I've got an exception there that was previously posted as a bug. But following instructions led me solve it.

I have one more question. I would like create a dsl which will control a workflow using a Java API. The documentation says I have to resolve the AST and call appropriate methods. Is it the only way doing so?
