-vast number of open source and commercial products - it even runs on the
 International Space Station!  Mongoose makes embedded network programming fast,
 robust, and easy. Features include:
 
 - Cross-platform:
   - works on Linux/UNIX, MacOS, Windows, Android
-  - works on STM32, NXP, ESP32, NRF52, TI, Microchip, and other
+  - works on ST, NXP, ESP32, Nordic, TI, Microchip, Infineon, Renesas and other chips
   - 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
+- Built-in protocols: plain TCP/UDP, SNTP, HTTP, MQTT, Websocket, and other
-- SSL/TLS support for mbedTLS and OpenSSL
 - 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
+- Easy to integrate: just copy [mongoose.c](https://raw.githubusercontent.com/cesanta/mongoose/master/mongoose.c)
-  [exact steps](https://mongoose.ws/documentation/#2-minute-integration-guide)

-- Works in any environment with socket API, like LwIP, Zephyr, Azure
 - Built-in TCP/IP stack with drivers for bare metal or RTOS systems
    - Available drivers: STM32F, STM32H; NXP RT1xxx; TI TM4C; Microchip SAME54; Wiznet W5500
-   - A complete Web device dashboard on bare metal
+   - A complete Web device dashboard on bare metal ST Nucleo boards is only 6 files

-- Built-in TLS 1.3 server-side support
+- Can run on top of an existing TCP/IP stack with BSD API, e.g. lwIP, Zephyr, Azure, etc
+- Built-in TLS 1.3 ECC stack. Also can use external TLS libraries - mbedTLS, OpenSSL, or other
 - Does not depend on any other software to implement networking

+- Built-in firmware updates for STM32 H5, STM32 H7
-- Detailed [user guide, API reference and tons of tutorials](https://mongoose.ws/documentation/)
 
-## 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"
+#include "mongoose.h"   // To build, run: cc main.c mongoose.c
-
-int main(void) {
-  struct mg_mgr mgr;  // Declare event manager
-  mg_mgr_init(&mgr);  // Initialise event manager
-  mg_http_listen(&mgr, "http://0.0.0.0:8000", fn, NULL);  // Setup listener
-  for (;;) {
-    mg_mgr_poll(&mgr, 1000);  // Run an infinite event loop
-  }
-  return 0;
-}
 
 // HTTP server event handler function
-void fn(struct mg_connection *c, int ev, void *ev_data) {
+void ev_handler(struct mg_connection *c, int ev, void *ev_data) {
   if (ev == MG_EV_HTTP_MSG) {
     struct mg_http_message *hm = (struct mg_http_message *) ev_data;
     struct mg_http_serve_opts opts = { .root_dir = "./web_root/" };
     mg_http_serve_dir(c, hm, &opts);
   }
 }
+
+int main(void) {
+  struct mg_mgr mgr;  // Declare event manager
+  mg_mgr_init(&mgr);  // Initialise event manager
+  mg_http_listen(&mgr, "http://0.0.0.0:8000", ev_handler, NULL);  // Setup listener
+  for (;;) {          // Run an infinite event loop
+    mg_mgr_poll(&mgr, 1000);
+  }
+  return 0;
+}
 ```
 
 HTTP server implements a REST API that returns current time. JSON formatting:
 ```c
-static void fn(struct mg_connection *c, int ev, void *ev_data) {
+static void ev_handler(struct mg_connection *c, int ev, void *ev_data) {
   if (ev == MG_EV_HTTP_MSG) {
     struct mg_http_message *hm = (struct mg_http_message *) ev_data;
-    if (mg_http_match_uri(hm, "/api/time/get")) {
+    if (mg_match(hm->uri, mg_str("/api/time/get"), NULL)) {
       mg_http_reply(c, 200, "", "{%m:%lu}\n", MG_ESC("time"), time(NULL));
     } else {
