+# Chapter Six: Expanding Bitcoin Transactions
+
+Basic bitcoin transactions: (1) send funds; (2) to a single P2PKH or SegWit recipient; (3) immediately. However, all three parts of this definition can be expanded using more complex Bitcoin transactions, which can alternatively send data, which can send to a group of recipients, or which can send at a later time. These three options represent further empowerment of Bitcoin and also the furthest boundaries of what you can do with the basic `bitcoin-cli` command.
+
+## Objectives for This Section
+
+After working through this chapter, a developer will be able to:
+
+   * Create Multisignature Bitcoin Addresses
+   * Create Transactions with Locktimes
+   * Create Transactions with Data
+   
+Supporting objectives include the ability to:
+
+   * Understand How to Spend Funds Sent to a Multisignature
+   * Plan for the Power of Multisignatures
+   * Understand the Different Sorts of Timelocks
+   * Plan for the Power of Locktime
+   * Plan for the Power of OP_RETURN
+

+# 6.7: Using a Partially Signed Bitcoin Transaction
+
+> :information_source: **NOTE:** This is a draft in progress, so that I can get some feedback from early reviewers. It is not yet ready for learning.
+
+[intro]
+
+> :warning: **VERSION WARNING:** This is an innovation from Bitcoin Core v 0.17.0. Earlier versions of Bitcoin Core will not be able to work with the PSBT while it is in process (though they will still be able to recognize the final transaction).
+
+## Use a PSBT to MultiSig
+
+## Use a PSBT to Pool Money
+
+## Use a PSBT to CoinJoin
+
+## Summary: Using a Partially Signed Bitcoin Transaction
+
+> :fire: ***What's the power of a PSBT?***
+
+## What's Next?
+
+Move on to "Bitcoin Scripting" with [Chapter Seven: Introducing Bitcoin Scripts](07_0_Introducing_Bitcoin_Scripts.md).
