+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 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, 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
+   - A complete Web device dashboard on bare metal ST Nucleo boards is only 6 files
+   - For comparison, a CubeIDE generated HTTP example is 400+ files
+- 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
 
+See https://mongoose.ws/ for complete documentation, videos, case studies, etc.
 
-# 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_http_match_uri(hm, "/api/time/get")) {
+      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:
-
-- Multiple logins with different permissions (admin and user)
-- Login screen for non-authenticated connections
-- A [preact](https://preactjs.com/)-based dashboard with multiple pages
-- Internal variables
-- A form that changes those variables
-- All changes are propagates to all connected clients
-- Live log stream
-- Live video stream
-
-
-In essence, this example is a combination of several other examples
-pulled together (multiple-logins, dashboard, live-log, video-stream).
-
-# Screenshots
-
-This is a login screen that prompts for user/password
-
-![](screenshots/login.png)
-
-# Main dashboard
-
-A main dashboard page shows internal data, live video stream, and a form
-
-![](screenshots/dashboard.png)
-
-A live log page shows live log stream coming from device

+# 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 possibly different permissions)
+- The Web UI can be fully embedded into the firmware binary, then not
+  needing a filesystem to serve it; so being resilient to FS problems
+- All changes are propagated to all connected clients
+
+See a detailed tutorial at https://mongoose.ws/tutorials/device-dashboard/
