 ### Transform the Hex to Binary
 
 To complete your serialization, you translate the hexcode into binary. On the command line, this just requires a simple invocation of `xxd -r -p`. However, you probably want to do that as part of a a single pipe that will also hash the script ...
 
+## Run The Integer Conversion Script

+A complete script for changing an integer between -2147483647 and 2147483647 to a little-endian signed-magnitude representation in hex can be found in th e[src code directory](src/10_2_integer2lehex.sh). You can download it as `integeer2lehex.sh`.

 ## Analyze a P2SH Multisig
 
 To better understand this process, we will reverse-engineer the P2SH multisig that we created in [§6.1: Sending a Transaction to a Multisig](06_1_Sending_a_Transaction_to_a_Multisig.md). Take a look at the `redeemScript` that you used, which you now know is the hex-serialized version of the locking script:
