No documentation for title.akas.tsv.gz

In the Interfaces page (https://www.imdb.com/interfaces/?ref_=helpms_ih_gi_siteindex), there is not listing of the fields and descriptions for the title.akas.tsv.gz file.  While the field names in the file are essentially self-evident, it would be helpful to have the documentation available so users can be certain of the data in the file.
