CSV flat file to IS Document

CSV files does not have any record identifiers, right? can some one explain me how to define records in FFDictionary for CSV and also about FF schema for CSV.
Here my point is how we can define record defination in Dictionary.
how the parser will identify the record.

CSV files can have record identifiers.

Follow the information in the Flat File Schema Developer’s Guide for defining records in a dictionary.

When defining the schema, you will specify which record definition to use for recordsWithNoID.

A record identifier for a flat file (e.g. csv) ist any arbitrary field which contains a value unique for that record type. This value must match the recordname in the dictionary to be properly assigned. All records which are not identified this way become a recordsWithNoID in the parsed document.
All necessary details in the guide Rob pointed out.
