 Each BIP should have the following parts:
 
-* Preamble -- RFC 822 style headers containing meta-data about the BIP, including the BIP number, a short descriptive title (limited to a maximum of 44 characters), the names, and optionally the contact info for each author, etc.
+* Preamble -- Headers containing metadata about the BIP ([[#Preamble|see below]]).
 
-* Abstract -- a short (~200 word) description of the technical issue being addressed.
+* Abstract -- A short (~200 word) description of the technical issue being addressed.
 
-* Copyright/public domain -- Each BIP must either be explicitly labelled as placed in the public domain (see this BIP as an example) or licensed under the Open Publication License.
+* Copyright -- The BIP must be explicitly licensed under acceptable copyright terms ([[#TODO|see below]]).
 
-* Specification -- The technical specification should describe the syntax and semantics of any new feature. The specification should be detailed enough to allow competing, interoperable implementations for any of the current Bitcoin platforms (Satoshi, BitcoinJ, bitcoin-js, libbitcoin).

-* Motivation -- The motivation is critical for BIPs that want to change the Bitcoin protocol. It should clearly explain why the existing protocol specification is inadequate to address the problem that the BIP solves. BIP submissions without sufficient motivation may be rejected outright.

-* Rationale -- The rationale fleshes out the specification by describing what motivated the design and why particular design decisions were made. It should describe alternate designs that were considered and related work, e.g. how the feature is supported in other languages.

-* Reference Implementation -- The reference implementation must be completed before any BIP is given status "Final", but it need not be completed before the BIP is accepted. It is better to finish the specification and rationale first and reach consensus on it before writing code.

-* The final implementation must include test code and documentation appropriate for the Bitcoin protocol.
