-This tool normalizes a VCF file annotated with the Variant Effect Predictor (VEP). 
+This tool modifies a VCF file annotated with the Variant Effect Predictor (VEP). 
 Since the VEP does not use INFO fields to annotate, but rather puts all its annotations in one big string inside a "CSQ" INFO tag it is necessary to normalize it. 
 
-This normalizer will use the information in the CSQ header to create INFO fields for each annotation field. 
-It has two modes: `standard` and `explode`. The `standard` mode will produce a VCF according to the VCF specification.

 This means that every VEP INFO tag will consist of the comma-separated list of values for each transcript.
 In case the value is empty, the VEP INFO tag will not be shown for that specific record
