  - works on STM32, NXP, ESP32, NRF52, TI, Microchip, and other
  - write code once - and it'll work everywhere
  - ideal for the unification of the network infrastructure code across company
- Built-in protocols: plain TCP/UDP, SNTP, HTTP, MQTT, Websocket
- SSL/TLS support for mbedTLS and OpenSSL
+- Built-in protocols: plain TCP/UDP, SNTP, HTTP, MQTT, Websocket, and other
 - Asynchronous DNS resolver
 - Tiny static and run-time footprint
 - Source code is both ISO C and ISO C++ compliant
- Very easy to integrate: just copy `mongoose.c` and `mongoose.h` files to your source tree. See
-  [exact steps](https://mongoose.ws/documentation/#2-minute-integration-guide)
- Works in any environment with socket API, like LwIP, Zephyr, Azure

-## Usage
+See https://mongoose.ws/ for complete documentation, videos, case studies, etc.
+
+## Usage Examples
+
+Below are quick snippets that should give an idea how simple the API is and
+how easy it is to create applications with it.

 Create a simple web server that serves a directory. The behavior of the
 HTTP server is specified by its event handler function:

 ```c
-#include "mongoose.h"
-
-int main(void) {
-  struct mg_mgr mgr;  // Declare event manager
-  mg_mgr_init(&mgr);  // Initialise event manager
