     insulin ingest </path/to/on_track_export_file.csv>
 
 This will take that file, parse it, and push the JSON into a number of collections in a MongoDB database called 'insulin'. You can view them with something like

+Currently the only supported output operation is

+    insulin day DATE

+to show stats for date DATE (in YYYY-MM-DD format) - defaults to 'today' if no date supplied. Note that insulin considers events that occur up to 04:00 as part of the previous actual day (because sometimes we stay up late, right?). Output will look something like

 You can also run the tests, if you're into that sort of thing:
 
     bundle exec rspec
 
-There's also some Postfix voodoo I've been using to extract the CSVs from incoming mail, which I'll document here soon.
+Postfix setup
+=============
+
+OnTrack allows you to mail the exported CSV files to an email address. [This page](http://tech.jeffri.es/2010/09/automatic-ripping-and-saving-email-attachments-with-postfix/) explains how to configure Postfix to extract those files. I now have this set up so that I mail from OnTrack to [e-mail], the CSVs get dropped into a directory, and then 'insulin ingest' runs periodically on the newest file in that directory.
