I suggest that we expand the section about the datasets that constitue the ERG treebanks: https://github.com/delph-in/docs/wiki/RedwoodsTop
Currently, the wiki page refers the reader to Flickinger 2011 but that work is not easily available online (I don't think?) Furthermore, even if one has it, it is still not fully obvious how to map the datasets described there to the files in the ERG release (for some, it is obvious, for others, it is not).
