 	Its purpose is to bring SQL expressive power to manipulating text data using the Linux command line.
 
 	Basic usage is q "<sql like query>" where table names are just regular file names (Use - to read from standard input)
-        Columns are named c1..cN and delimiter can be set using the -d (or -t) option.
+        When the input contains a header row, use -H, and column names will be set according to the header row content. If there isn't a header row, then columns will automatically be named c1..cN.
+
+	Column types are detected automatically. Use -A in order to see the column name/type analysis.
+
+	Delimiter can be set using the -d (or -t) option. Output delimiter can be set using -D
 
 	All sqlite3 SQL constructs are supported.
