 ### Parser and configuration
 
 Pasrer can take several parameters like that:
 
 ```
-	definition, file_path_or_data, ignore_blank_line=false
+	definition, file_path_or_data, ignore_blank_line: false
 ```
 
 in file_path_or_data attribute you can pass directly an Array of data (Array with 2 dimensions) really useful for testing, if you don't care about blank lines in your CSV you can ignore them.
