 /**
- * @mainpage Mbed Crypto v0.1.0 source code documentation
+ * @mainpage mbed TLS v2.17.0 source code documentation
  *
  * This documentation describes the internal structure of mbed TLS.  It was
  * automatically generated from specially formatted comment blocks in
  * mbed TLS's source code using Doxygen.  (See
  * http://www.stack.nl/~dimitri/doxygen/ for more information on Doxygen)
  *
- * Mbed Crypto provides an implementation of the PSA Crypto API. The library is
- * comprised of a number of independent modules, listed in the \ref
- * mainpage_modules "Modules section". This "Modules section" introduces the
- * high-level module concepts used throughout this documentation.
+ * mbed TLS has a simple setup: it provides the ingredients for an SSL/TLS
+ * implementation. These ingredients are listed as modules in the
+ * \ref mainpage_modules "Modules section". This "Modules section" introduces
+ * the high-level module concepts used throughout this documentation.\n
+ * Some examples of mbed TLS usage can be found in the \ref mainpage_examples
+ * "Examples section".
  *
  * @section mainpage_modules Modules
  *
- * Mbed Crypto provides the following modules:
+ * mbed TLS supports SSLv3 up to TLSv1.2 communication by providing the
+ * following:
+ * - TCP/IP communication functions: listen, connect, accept, read/write.
+ * - SSL/TLS communication functions: init, handshake, read/write.
+ * - X.509 functions: CRT, CRL and key handling
  * - Random number generation
  * - Hashing
  * - Encryption/decryption
  *
  * Above functions are split up neatly into logical interfaces. These can be
- * used separately to provide any of the above functions or to mix-and-match.
+ * used separately to provide any of the above functions or to mix-and-match
+ * into an SSL server/client solution that utilises a X.509 PKI. Examples of
+ * such implementations are amply provided with the source code.
  *
+ * Note that mbed TLS does not provide a control channel or (multiple) session
+ * handling without additional work from the developer.
+ *
+ * @section mainpage_examples Examples
+ *
+ * Example server setup:
+ *
+ * \b Prerequisites:
+ * - X.509 certificate and private key
+ * - session handling functions
+ *
+ * \b Setup:
+ * - Load your certificate and your private RSA key (X.509 interface)
+ * - Setup the listening TCP socket (TCP/IP interface)
+ * - Accept incoming client connection (TCP/IP interface)
+ * - Initialise as an SSL-server (SSL/TLS interface)
+ *   - Set parameters, e.g. authentication, ciphers, CA-chain, key exchange
+ *   - Set callback functions RNG, IO, session handling
+ * - Perform an SSL-handshake (SSL/TLS interface)
+ * - Read/write data (SSL/TLS interface)
+ * - Close and cleanup (all interfaces)
+ *
+ * Example client setup:
+ *
+ * \b Prerequisites:
+ * - X.509 certificate and private key
+ * - X.509 trusted CA certificates
+ *
+ * \b Setup:
+ * - Load the trusted CA certificates (X.509 interface)
+ * - Load your certificate and your private RSA key (X.509 interface)
+ * - Setup a TCP/IP connection (TCP/IP interface)
+ * - Initialise as an SSL-client (SSL/TLS interface)
+ *   - Set parameters, e.g. authentication mode, ciphers, CA-chain, session
+ *   - Set callback functions RNG, IO
+ * - Perform an SSL-handshake (SSL/TLS interface)
+ * - Verify the server certificate (SSL/TLS interface)
+ * - Write/read data (SSL/TLS interface)
+ * - Close and cleanup (all interfaces)
