+Mongoose is a network library for C/C++.  It provides event-driven non-blocking
+APIs for TCP, UDP, HTTP, WebSocket, MQTT, and other protocols.  It is designed
+for connecting devices and bringing them online. On the market since 2004, used
+by 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, FreeRTOS, etc.
-- Supported embedded architectures: ESP32, NRF52, STM32, NXP, and more
-- Built-in protocols: plain TCP/UDP, HTTP, MQTT, Websocket
-- SSL/TLS support: mbedTLS, OpenSSL or custom (via API)
+- Cross-platform:
+  - works on Linux/UNIX, MacOS, Windows, Android
+  - 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, and other
 - Asynchronous DNS resolver
 - Tiny static and run-time footprint
 - Source code is both ISO C and ISO C++ compliant
-- Works with any network stack with socket API, like LwIP or FreeRTOS-Plus-TCP
-- Very easy to integrate: just copy `mongoose.c` and `mongoose.h` files to your build tree
-- Detailed [documentation](https://mongoose.ws/documentation/) and
-  [tutorials](https://mongoose.ws/tutorials/)
+- Easy to integrate: just copy [mongoose.c](https://raw.githubusercontent.com/cesanta/mongoose/master/mongoose.c)
+  and [mongoose.h](https://raw.githubusercontent.com/cesanta/mongoose/master/mongoose.h) files to your source tree
+- 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

-# Commercial use
+## 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"   // To build, run: cc main.c mongoose.c
+
+// HTTP server event handler function
+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 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_match(hm->uri, mg_str("/api/time/get"), NULL)) {
+      mg_http_reply(c, 200, "", "{%m:%lu}\n", MG_ESC("time"), time(NULL));
+    } else {
+      mg_http_reply(c, 500, "", "{%m:%m}\n", MG_ESC("error"), MG_ESC("Unsupported URI")); 
+    }
+  }
+}
+```
+
+MQTT client that subscribes to a topic `device1/rx` and
+echoes incoming messages to `device1/tx`:
+
+```c
+#include "mongoose.h"
+
+static const char *s_mqtt_url = "mqtt://broker.hivemq.com:1883";
+static struct mg_connection *s_mqtt_conn = NULL;
+
+// MQTT connection event handler function
+static void ev_handler(struct mg_connection *c, int ev, void *ev_data) {
+  if (ev == MG_EV_OPEN) {
+    MG_INFO(("%lu created, connecting to %s ...", c->id, s_mqtt_url));
+  } else if (ev == MG_EV_MQTT_OPEN) {
+    struct mg_mqtt_opts opts = {.qos = 1, .topic = mg_str("device1/rx")};
+    mg_mqtt_sub(c, &opts);
+    MG_INFO(("%lu connected, subscribing to %s", c->id, opts.topic.buf));
+  } else if (ev == MG_EV_MQTT_MSG) {
+    char response[100];
+    struct mg_mqtt_message *mm = (struct mg_mqtt_message *) ev_data;
+    struct mg_mqtt_opts opts = {.qos = 1, .topic = mg_str("device1/tx")};
+    mg_snprintf(response, sizeof(response), "Received [%.*s] / [%.*s]",
+                mm->topic.len, mm->topic.buf, mm->data.len, mm->data.buf);
+    opts.message = mg_str(response);
+    mg_mqtt_pub(c, &opts);
+  } else if (ev == MG_EV_CLOSE) {
+    MG_INFO(("%u closing", c->id));
+    s_mqtt_conn = NULL;
+  }
+}
+
+// Reconnection timer function. If we get disconnected, reconnect again
+static void timer_fn(void *arg) {
+  struct mg_mgr *mgr = (struct mg_mgr *) arg;
+  if (s_mqtt_conn == NULL) {
+    struct mg_mqtt_opts opts = {.clean = true};
+    s_mqtt_conn = mg_mqtt_connect(mgr, s_mqtt_url, &opts, ev_handler, NULL);
+  }
+}
+
+int main() {
+  struct mg_mgr mgr;  // Mongoose event manager. Holds all connections
+  mg_mgr_init(&mgr);  // Initialise event manager
+  mg_timer_add(&mgr, 3000, MG_TIMER_REPEAT | MG_TIMER_RUN_NOW, timer_fn, &mgr);
+  for (;;) {
+    mg_mgr_poll(&mgr, 1000);  // Infinite event loop
+  }
+  return 0;
+}
+```

-# A complete device dashboard
-
-This example is a demonstration of how Mongoose Library could be integrated
-into an embedded device and provide a complete device dashboard with the
-following features:
-
-- Authentication: login-protected dashboard
-- Multiple logins with different permissions (admin and user)
-- Web UI is fully embedded into the server/firmware binary, and does not
-  need a filesystem to serve it. UI is resilient to FS problems
-- Administrators can change server settings
-- All changes are propagates to all connected clients
-- A device is connected to the external MQTT server
-- Logged in clients can send/receive messages to a device which get
-  forwarded to MQTT
-
-# Screenshots
-
-This is a login screen that prompts for user/password
-
-![](screenshots/login.png)
-
-# Main dashboard
-
-A main dashboard page shows and interactive MQTT console

-  This device dashboard is developed using the modern and compact Preact framework,

-  a <a href="https://mongoose.ws/tutorials/http-server/">hybrid server</a> which
-  provides both static and dynamic content.  Static files, like CSS/JS/HTML
-  or images, are compiled into the server binary.
-
-  This UI uses the REST API implemented by the device, which you can examine
-  using  <code>curl</code> command-line utility:
-  </p>
-
-  <div><code>curl -u admin:pass0 localhost:8000/api/config/get</code> </div>
-  <div><code>curl -u admin:pass0 localhost:8000/api/config/set -d 'pub=mg/topic'</code> </div>
-  <div><code>curl -u admin:pass0 localhost:8000/api/message/send -d 'message=hello'</code> </div>
-
-  <p>
-  The device can send notifications to this dashboard at anytime. Notifications
-  are sent over WebSocket at URI <code>/api/watch</code> as JSON strings: <code>{"name": "..", "data": ...}</code>
-  <div>Try <code>wscat --auth user1:pass1 --connect ws://localhost:8000/api/watch</code></div>

-# An example ESP8266 application
-
-To build this application, follow these steps:
-
-1. Make sure you have Docker installed
-2. Clone whole mongoose repository on your machine:
-  ```sh
-  git clone https://github.com/cesanta/mongoose.git
-  ```
-3. Start command line or terminal, and go into the example's directory:
-  ```sh
-  cd mongoose/examples/esp8266
-  ```
-4. Run `make`. This invokes a Docker-based build. A firmware will be built
-  in the `src/build/` directory:
-  ```sh
-  make build
-  ```
-5. Flash your ESP8266. If you have esptool.py installed, the build process will end telling you the command to flash your device. You can just run `make` again to use Docker:
-  ```sh
-  make flash PORT=/your/serial
-  ```

-# Baremetal webserver on NUCLEO-F746ZG
-
-This firmware uses experimental TCP/IP stack of the Mongoose Network Library,
-which implements the following:
-
-- Implements HTTP server and SNTP time synchronisation
-- No dependencies: no HAL, no CMSIS, no RTOS
-- Hand-written [mcu.h](mcu.h) header based on a [datasheet](https://www.st.com/resource/en/reference_manual/rm0385-stm32f75xxx-and-stm32f74xxx-advanced-armbased-32bit-mcus-stmicroelectronics.pdf)
-- Interrupt-driven [driver_stm32.c](../../../mip/driver_stm32.c) ethernet driver
-- Blue LED blinky, based on SysTick interrupt
-- User button handler, turns off/on green LED, based on EXTI, interrupt-driven 
-- HardFault handler that blinks red LED
-- Debug log on UART3 (st-link)
-
-## Requirements
-
-- GNU make
-- [ARM GCC](https://developer.arm.com/tools-and-software/open-source-software/developer-tools/gnu-toolchain/gnu-rm) toolchain for build
-- [st-link](https://github.com/stlink-org/stlink) for flashing
-
-## Usage
-
-Plugin your Nucleo board into USB, and attach an Ethernet cable.
-To build and flash:
-
-```sh
-$ make clean flash
-```
-
-To see debug log, use any serial monitor program like `picocom` at 115200 bps and configure it to insert carriage returns after line feeds:
-
-```sh
-$ picocom /dev/ttyACM0 -i -b 115200 --imap=lfcrlf
-```
-
-## Benchmark
-
-A quick comparison is made with several other implementations.
-Note: `IP` in the table below is the IP address printed on the console after
-boot. The benchmark command is the same: `siege -c 5 -t 5s http://IP`
-
-|                     | Zephyr   | LWIP sockets | LWIP raw | MIP  |
-| ------------------- | -------- | ------------ | -------- | ---- |
-| Requests per second | 3        | 16           | 286      | 1080 |
-| Firmware size       | 117k (*) | 160k         | 114k     | 28k  |
-
-- Zephyr: uses Zehypr's RTOS and TCP stack, with Mongoose library on top,
-  [source code](https://github.com/cesanta/mongoose/tree/master/examples/zephyr/http-server).
-  (*) By default, Zephyr example is TLS-enabled. To compare sizes, a TLS-disabled
-  build was done by disabling TLS in `prj.conf` and `CMakeLists.txt`
-- LWIP sockets: uses FreeRTOS and LWIP with sockets support, with Mongoose
-  library on top, [source code](https://github.com/mongoose-examples/stm32-nucleo-f746z).
-  built with `#define MG` in `Core/main.c`
-- LWIP raw: uses FreeRTOS and LWIP without sockets, LWIP's httpd server,
-  [source code](https://github.com/mongoose-examples/stm32-nucleo-f746z).
-  built with `#define MG` line commented out in `Core/main.c`
-- MIP: this repository
