 This demo script exercises a Pay to <glossary:Multisig> contract written in SimplicityHL by performing a real transaction to and from this contract on the Liquid Testnet. Most commands are printed as they are run. You can look at the contents of `p2ms-demo.sh` to understand more about the steps it performs, or use it as a basis for performing Liquid Testnet transactions with other Simplicity contracts. At the end of the process, you'll see a link to the <a href="https://blockstream.info/">Explorer</a> to look at the details of the resulting transaction.
