+    - wolfcrypt unit test application
+- zephyr/samples/crypto/wolfssl_tls_sock
+    - socket based sample of TLS
+- zephyr/samples/crypto/wolfssl_tls_thread
+    - socket based sample of TLS using threads
+
+## How to setup
+
+### delopy wolfssl source to mynewt project
+Specify the path of the mynewt project and execute  `wolfssl/IDE/mynewt/setup.sh`.
+
+```bash
+./IDE/zephyr/setup.sh　/path/to/zephyrproject
+```
+
+This script will deploy wolfssl's library code and samples as described in the Overview to the zephyr project.
