+ESP-TLS
+=======
+
+Overview
+--------
+
+The ESP-TLS component provides a simplified API interface for accessing the commonly used TLS functionality. 
+It supports common scenarios like CA certification validation, SNI, ALPN negotiation, non-blocking connection among others. 
+All the configuration can be specified in the esp_tls_cfg_t data structure. Once done, TLS communication can be conducted using the following APIs:
+* esp_tls_conn_new(): for opening a new TLS connection
+* esp_tls_conn_read/write(): for reading/writing from the connection
+* esp_tls_conn_delete(): for freeing up the connection
+Any application layer protocol like HTTP1, HTTP2 etc can be executed on top of this layer.                       
+
+Application Example
+-------------------
+
+Simple HTTPS example that uses ESP-TLS to establish a secure socket connection: :example:`protocols/https_request`.
