_DESCRIPTION = """\
United States governmental agencies often make proposed regulations open to the public for comment. 
Proposed regulations are organized into "dockets". This dataset will use Regulation.gov public API 
to aggregate and clean public comments for dockets that mention opioid use. 

Each example will consist of one docket, and include metadata such as docket id, docket title, etc. 
Each docket entry will also include information about the top 10 comments, including comment metadata
and comment text.
