 ===Specification===
 
+New BIPs may be accepted with the following licenses. Each new BIP must identify at least one acceptable license in its preamble. The License header in the preamble must be placed after the Created header. Each license must be referenced by their respecitve abbreviation given below.
+
+For example, a preamble might include the following License header:
+
+    License: PD
+             CC-0
+             MIT
+

 In addition, it is recommended that literal code included in the BIP be dual-licensed under the same license terms as the project it modifies. For example, literal code intended for Bitcoin Core would ideally be dual-licensed under the MIT license terms as well as one of the above with the rest of the BIP text.
