 ## Abstract
 
 This CIP extends CIP-0009 to include the new protocol parameters that have been introduced for Alonzo, specifically those relating to the costing of Plutus scripts.  It describes the initial settings for those parameters.
 
-## Motivation
+## Motivation: why is this CIP necessary?
 
 We need to document the chain of changes to the protocol parameters.  This document describes precisely the changes that have been made from CIP-0009, allowing the differences to be determined.  It thus supplements rather than replaces CIP-0009.
 
 ## Specification

 ### New Updatable Protocol Parameters
 
 The new **updatable** protocol parameter values for Alonzo are given below (in JSON format).  Any of these parameters may be changed by submitting

 The majority of the parameters are needed to enable the use of Plutus scripts on-chain.  They relate to the fees calculations for
 transactions that include Plutus scripts.
