@marc_aurel I'm not very familiar with it, and haven't used it myself, so unfortunately not. It seems like maybe there is an issue with the version of lxd in use on your system. Probably should ask about that separately.
But as I said, there isn't really much useful in terms of documentation in the unity8 tree. So for what you are looking for, is likely a waste of time to build it. Also, as scopes are going away, I suppose it doesn't make sense to publish the documentation. IIRC, most of the documentation is about widgets provided by Unity which scopes can "use" in their search results and previews.
