 #### Create the Hex Code
 
 Creating the hexcode that is necessary to serialize a script is both a simple translation and something that's complex enough that it goes beyond any shell script that you're likely to write. As with a few other aspects of P2SH scripts, it's something that you'll probably process through an API, not by hand.

 #### Create the Hex Code: A Multisig Example
 
 It may be easier to understand this by taking an existing hexcode and translating it back to Bitcoin Script. For example, look at the `redeemScript` that you used [§6.1](6_1_Sending_a_Transaction_to_a_Multisig.md):
