So how do you write a more complex Bitcoin Script? The answer is in that last sort of standard transaction, the P2SH. You can put any sort of long and complex script into a P2SH transaction, and as long as you follow the standard rules for embedding your script and for redeeming the funds, you'll get all the benefits of Bitcoin Scripting.

> **VERSION WARNING:** Arbitrary (non-standard) P2SH scripts only became standard as of Bitcoin Core 0.10.0. Before that only P2SH Multisigs were allowed.

You already saw a P2SH transaction when you created a multisig in [6.1: Sending a Transaction to a Multisig](6_1_Sending_a_Transaction_to_a_Multisig.md). Though multisig is one of the standard transaction type, `bitcoin-cli` actually simplifies the usage of its multisigs by embedding them into P2SH transactions, as described more fully in the next section.
