+### Overview
+This layer provides the support of Intel Software Guard Extensions
+(Intel SGX), which is an Intel technology for application developers
+seeking to protect select code and data from disclosure or modification.
+
+The Linux SGX software stack is comprised of the Intel SGX driver, the
+Intel SGX SDK, and the Intel SGX Platform Software.
+
+### Intel SGX Driver
+The recipe sgx-driver provides a out-of-tree driver for the Linux Intel
+SGX software stack, which will be used until the driver upstreaming process
+is complete.
+
+### Intel SGX SDK and PSW
+The recipes are still in development.
+
+### Hardware Support
+Please check [this site](https://github.com/ayeks/SGX-hardware) for the
+latest information.
+
+### Reference
