+Each file of the form

+in the current directory is a configuration file used to
+import transactions from a financial institution.
+Like all
+.Xr pta 1
+input files, it is an

+text file using strings of one or more space characters
+as the field delimiter and using the hash character
+.Pq Sq #
+in the first column to mark lines as ignored.
+.Pp
+Each file contains one line beginning with

+and is followed by whitespace and then an account number.
+.Pp
+Each file contains lines of the form
+.Pp
+.Ar selector account_number booking_identifier
+.Pp
+The
+.Ar selector
+is a string consisting of regular expressions
+separated by commas.
+Its fields correspond to header fields in the financial
+institution's CSV file and is used to classify transactions
+that match the search pattern.
+The first selector that
+matches a transaction wins.
+.Pp
+The
+.Ar account_number
+corresponds to an account number in

+The
+.Ar booking_identifier
+is defined by the user to classify

 Add journal entries to a journal file using a CSV file generated by
 a financial institution:
 .Pp
-.Dl "$ pta_import MyCreditCard1234.csv >> journal.txt"

+.Dl Transaction Date,Post Date,Description,Category,Type,Amount
 .Pp
-to reflect that the account they are importing is 1234 in
-.Pa ./accounts.txt .
+Then this
+.Ar selector
+ignores the transaction date, post date, description, type, and amount.
+It matches the

+category and maps transactions to account
