+## Best practices
+
+- If you need to perform any sort of initialisation of your connection,
+  do it by catching `MG_EV_OPEN` event. That event is sent immediately
+  after a connection has been allocated and added to the event manager,
+  but before anything else:
+  ```c
+  static void fn(struct mg_connection *c, int ev, void *ev_data, void *fn_data) {
+    if (ev == MG_EV_OPEN) {
+      ... // Do your initialisation
+    }
+  ```
+- If you need to keep some connection-specific data, you have two options.
+  First, use `c->fn_data` pointer. That pointer is passed to the event handler
+  as last parameter:
+  ```c
+  static void fn(struct mg_connection *c, int ev, void *ev_data, void *fn_data) {
+    if (ev == MG_EV_OPEN) {
+      c->fn_data = malloc(123);       // Change our fn_data
+    } else if (ev == MG_EV_CLOSE) {
+      free(fn_data);  // Don't forget to free!
+    }
+    ...
+  }
+
+  // Every accepted connection inherit NULL pointer as c->fn_data, but we change
+  // it per-connection to something else
+  mg_http_listen(&mgr, "http://localhost:1234", fn, NULL);
+  ```
+  Another option is to use `c->label` buffer, which can
+  hold some amount of connection-specific data without extra memory allocation:
+  ```c
+  static void fn(struct mg_connection *c, int ev, void *ev_data, void *fn_data) {
+    if (ev == MG_EV_WS_OPEN) {
+      c->label[0] = 'W'; // Established websocket connection, store something
+      ...
+  ```
+- If you need to close the connection, set `c->is_draining = 1;` in your
+  event handler function. That tells the event manager to send all remaining
+  data in a send buffer ("drain" the connection), then close the connection.
+  If you need to close
+  the connection immediately without draining, use `c->is_closing = 1;`
+- Use `mg_http_reply()` function to create HTTP responses. That function
+  properly sets the `Content-Length` header, which is important. Of course
+  you can create responses manually, e.g. with `mg_printf()` function,
+  but be sure to set the `Content-Length` header:
+  ```c
+  mg_printf(c, "HTTP/1.1 200 OK\r\Content-Length: %d\r\n\r\n%s", 2, "hi");
+  ```
+  Alternatively, use chunked transfer enconding:
+  ```c
+  mg_printf(c, "HTTP/1.1 200 OK\r\nTransfer-Encoding: chunked\r\n\r\n");
+  mg_http_printf_chunk(c, "%s", "foo");
+  mg_http_printf_chunk(c, "%s", "bar");
+  mg_http_printf_chunk(c, "");  // Don't forget the last empty chunk
+  ```
+- On embedded environment, make sure that serving task has enough stack:
+  give it 2k for simple RESTful serving, or 4-8k for complex dynamic/static
+  serving. In certain environments, it is necessary to adjust heap size, too.
+  By default, IO buffer allocation size `MG_IO_SIZE` is 2048: change it to 512
+  to trim run-time per-connection memory consumption.

-Create a "pipe" connection which is safe to pass to a different task/thread
-and used to wake up event manager from a different task. These
-functions are designed to implement multi-threaded support, to handle two
-common use cases:
-
- There are multiple consumer connections, e.g. connected websocket clients.
-  A server constantly pushes some data to all of them. In this case, a data
-  producer task should call `mg_mgr_wakeup()` as soon as more data is produced.
-  A pipe's event handler should push data to all client connection.
-  Use `c->label` to mark client connections.
- In order to serve a request, a long blocking operation should be performed.
-  In this case, request handler assigns some marker to `c->label` and then
-  spawns a handler task and gives a pipe to a
-  handler task. A handler does its job, and when data is ready, wakes up a
-  manager. A pipe's event handler pushes data to a marked connection.
-
-Another task can wake up a sleeping event manager (in `mg_mgr_poll()` call)
-using `mg_mgr_wakeup()`. When an event manager is woken up, a pipe
-connection event handler function receives `MG_EV_READ` event.
+Wrap a given file descriptor `fd` into a connection, and add that connection

+`select()` syscalls, and be non-blocking. Mongoose will treat it as a TCP
+socket. The `c->rem` and `c->loc` addresses will be empty.

 Parameters:
+- `fd` - A file descriptor to wrap
 - `mgr` - An event manager
 - `fn` - A pointer to event handler function
 - `ud` - A user data pointer. It will be passed to `fn` as `fn_data` parameter

+Parameters:

-# 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 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
+- View and change server settings
+- All changes are propagates to all connected clients
+- Live interactive chat that demonstrates bi-directional data exchange
+
+# Screenshots
+
+This is a login screen that prompts for user/password
+
+![](screenshots/login.png)
+
+# Main dashboard
+
+A main dashboard page shows device settings form, and live chat

      <div id="info">
        Mongoose always buffers a full HTTP message before invoking
        MG_EV_HTTP_MSG event. Big POST request require of lot
-        of RAM to buffer everything. Therefore, in order to upload large
-        files on memory-constrained system, a large file should be send
-        in small chunks.
-        <br/><br/>
-        In this example, JavaScript code on this page sends uploaded
-        file in 2k chunks using an <code>/upload</code> endpoint.
-        Uploaded file is stored in <code>/tmp</code> directory by the helper
-				API function <code>mg_http_upload()</code>
+        of RAM to buffer everything.
+        <br><br>
+        In order to upload large files to a memory-constrained system, use
+        <code>MG_EV_HTTP_CHUNK</code> on a server side. It fires when
+        a partial HTTP message has been received (or a chunk-encoded chunk).
+        Use <code>mg_http_delete_chunk()</code> to release chunk memory.
+        When 0-sized chunk is received, that's the end of the message.
+        Use <code>MG_MAX_RECV_BUF_SIZE</code> build constant to limit
+        maximum chunk size on a server side.
+        <br><br>
+        In this example, JavaScript code uses "fetch()" browser API.
+        Uploaded file is not saved, but rather printed by server side.
