I thought you might appreciate some feedback from a complete newbie on the installation instructions.
I followed the instructions on: http://www.eclipse.org/xtend/download.html. The first hurdle is that the update site offers a lot of options, and the download page doesn't say anything about which of them I need. I guessed "Xpand/Xtend All-In-One", but shouldn't the documentation be more explicit about this rather fundamental question?
There also seems to be a gap in the documentation between installing the SDK and actually creating an Xtend class? I figured out that you need to create a Java project (I wasted a minute or two looking for the option to create an Xtend project), and then go to "New -> Other..." and find the Xtend Class option.
It would also be really useful to have a tutorial about how to set up an Xtend Maven project. There is some information on the Download page, but it's not really a walk-through, and it's not really clear to me how exactly Eclipse interacts with Maven as it relates to Xtend.
I think it would really help the project if more attention was given to some introductory tutorials that walked the user through creating a new Xtend project, and perhaps any setup of the IDE to make Xtend easier to use.
Hope that feedback is useful,
Ian.
