+## Introduction
+This Mbed TLS layer is ported from the open source Mbed TLS, and we only modified the needed parts
+to adapt to AliOS Things, so this layer provides the same APIs and features as the open source
+Mbed TLS. For details, please refer to https://tls.mbed.org/ .
+
+The major modification for porting Mbed TLS includes:
+- provides our network socket APIs in aos/library/net_sockets.c
+- provides our threading mutex APIs in aos/library/threading_alt.c
+- provides our memory management APIs in aos/library/platform.c
+- provides our configuration in include/mbedtls/config.h
