+# Build Attributes for the Arm® 64-bit Architecture (AArch64)
+
+## About this document
+
+The [Build Attributes for the Arm 64-bit Architecture](buildattr64.rst)
+describes the implementation of build attributes for the 64-bit
+Arm Architecture.
+
+## About the license
+
+As identified more fully in the [LICENSE](LICENSE) file, this project
+is licensed under CC-BY-SA-4.0 along with an additional patent
+license.  The language in the additional patent license is largely
+identical to that in Apache-2.0 (specifically, Section 3 of Apache-2.0
+as reflected at https://www.apache.org/licenses/LICENSE-2.0) with two
+exceptions.
+
+First, several changes were made related to the defined terms so as to
+reflect the fact that such defined terms need to align with the
+terminology in CC-BY-SA-4.0 rather than Apache-2.0 (e.g., changing
+“Work” to “Licensed Material”).
+
+Second, the defensive termination clause was changed such that the
+scope of defensive termination applies to “any licenses granted to
+You” (rather than “any patent licenses granted to You”).  This change
+is intended to help maintain a healthy ecosystem by providing
+additional protection to the community against patent litigation
+claims.
+
