-# 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;
+}
+```

-
-  <p>
-  This device dashboard is developed using the modern and compact Preact framework,
-  in order to fit on very small devices. This is
-  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 ${devaddr}/api/config/get</code> </div>
-  <div><code>curl -u admin:pass0 ${devaddr}/api/config/set -d 'pub=mg/topic'</code> </div>
-  <div><code>curl -u admin:pass0 ${devaddr}/api/message/send -d 'message=hello'</code> </div>
-
-  <p>
-  The device can send notifications to this dashboard at anytime. Notifications
-  are sent over WebSocket at URI <code>/api/watch</code> as JSON strings: <code>{"name": "..", "data": ...}</code>
-  <div>Try <code>wscat --auth user1:pass1 --connect ws://${devaddr}/api/watch</code></div>

+# File Transfer
+
+This example contains minimal HTTP client and server.
+
+The client uploads a file to the server in a single POST, shaping traffic to send small data chunks.
+
+The server manually processes requests in order to be able to write as soon as data arrives, to avoid buffering a whole (possibly huge) file not fitting in RAM.
+
+Uploads are authenticated using Basic Auth. Both client and server have a default user/pass and can be configured using the command line. Only authenticated users can upload a file.
+
+The server can also accept regular uploads from any HTTP client, for example curl:
+
+```sh
+	curl -su user:pass  http://localhost:8090/upload/foo.txt --data-binary @Makefile
+```
+
+- Follow the [Build Tools](../tools/) tutorial to setup your development environment.
+- Start a terminal in this project directory; and build the example:
+
+  ```sh
+  cd mongoose/examples/file-transfer
+  make clean all
+  ```
+
+- Manually start the server, either in background (to reuse the same terminal window) or in foreground; in which case you'll need another terminal to run the client. The server will listen at all interfaces in port 8090
+
+  ```sh
+  ./server
+  6332b7 2 server.c:157:main              Mongoose version : v7.12
+  6332b7 2 server.c:158:main              Listening on     : http://0.0.0.0:8090
+  6332b7 2 server.c:159:main              Web root         : [/home/mongoose/examples/file-transfer/web_root]
+  6332b7 2 server.c:160:main              Uploading to     : [/home/mongoose/examples/file-transfer/upload]
+  ```
+
+- Manually run the client to send a file, default is to send it as "foo.txt" to the server in localhost at port 8090
+
+  ```sh
+  ./client -f Makefile
+  ok
+  ```
+
+Default operation is to assume hardcoded username and password. Call both server and client with no arguments to see usage instructions
